5 Explanation of terminology
The following terms are used in this user manual:
5.1 Pedelec/EPAC
Contrary to the official standard, EPACs (electric power-assisted cycles) are referred to in
this user manual as pedelecs (from “pedal electric cycle”).
The following paragraph is only applicable for Europe:
Pedelecs are cycles with an electric auxiliary motor that provides assistance up to a maxi-
mum of 25 km/h (15.5 mph) when you pedal.
Depending on the cycle model, there may be a pushing aid which can accelerate the cycle
up to 6 km/h (4 mph) depending on what gear the shifting system is in.
Guide Explanation of terminology
5
The following paragraph is only applicable for the USA:
Pedelecs are cycles with an electric auxiliary motor that provides assistance up to a max-
imum of 20 mph when you pedal. By law, pedelecs are class 1 (see the “Explanation of
symbols” chapter). There may be a pushing aid depending on the cycle model. How this
functions is described in more detail in the drive system user manual enclosed with the
cycle.
Pedelecs are cycles that are legally classed as bikes in most countries. Acquaint yourself
with the national and regional regulations and classification in your country.
5.2 S-pedelec/S-EPAC
Contrary to the official standard, S-EPACs (speed electric power-assisted cycles) are re-
ferred to in this user manual as S-pedelecs (from “speed pedal electric cycle”). The follow-
ing paragraph is only applicable for Europe:
S-pedelecs are cycles with an electric auxiliary motor that provides assistance up to a
maximum of 45 km/h (28 mph) when you pedal. Depending on the model, all-electric op-
eration up to a maximum of 18 km/h (11 mph) may also be possible.
The following paragraph is only applicable for the USA:
S-pedelecs are cycles with an electric auxiliary motor that provides assistance up to a
maximum of 28 mph when you pedal. There may be a pushing aid depending on the cycle
model. How this functions is described in more detail in the drive system user manual
enclosed with the cycle. By law, S-pedelecs are class 3 (see the “Explanation of symbols”
chapter). In some countries, S-pedelecs are classed as motor vehicles. Acquaint yourself
with the national and regional regulations and classification in your country.
5.3 Children’s bikes
Children’s bikes are pedal-powered category 0 cycles for children, with 12" and 16"
wheels.
GuideExplanation of terminology
6
5.4 Balance bikes
Balance bikes are category 0 cycles without pedals for children aged 3 years and up. Bal-
ance bikes are pushed along as the child moves.
5.5 Crankset
A crankset (sometimes known as a chainset) is an assembly consisting of chainrings, ped-
als and cranks.
1 Chainring
2 Pedal
3 Crank
Illustr.: Crankset using the example of a derailleur shifting system with 3 chainrings
5.6 Sag
Sag is the amount of compression in suspension elements which is caused by the rider’s
body weight. Depending on the model of the suspension fork or suspension, and depend-
ing on the intended use, the sag is adjusted to a value between 15 % and 40 % of the total
suspension travel.
5.7 Lockout
The lockout feature locks the suspension fork. This can reduce bob or squat in the front
fork, e.g. where the suspension sinks when pedalling hard.
Depending on the cycle model, the rear suspension may also be equipped with a lockout
feature (see the “Suspension” chapter in the cycle user manual).

1 Basics
1.1 Reading and storing the user manual
This user manual is part of your cycle. The cycle user manual refers to bikes, racing
bikes, pedelecs, S-pedelecs, children’s bikes and balance bikes collectively as cy-
cles. The user manual contains important information about adjustment and use.
Read the entire user manual carefully, paying particular attention to the safety
notes, before using the cycle. Also carefully and thoroughly read the supplemen-
tary user manuals depending on the cycle model and cycle category. Failure to
follow this user manual may result in serious injury or damage to the cycle. Keep
the user manual to hand. If passing the cycle on to a third party, it is essential that
you include this user manual along with it.
1.2 Proper use
Neither the manufacturer nor the dealer accept any liability for damage caused due to im-
proper use. Use the cycle only as described in this user manual. Any other use is deemed
improper and may result in accidents, serious injury or damage to the cycle.
Converting a cycle into a pedelec or S-pedelec through retrofitting is not permitted.
Manipulating the drive unit on pedelecs and S-pedelecs is prohibited.
Changes or conversions to the vehicle that change the characteristics of the vehicle (e.g.
ski runners, load transport attachments, sidecars) are not permitted.
Warranty claims may be endangered and may expire if the vehicle is not used as intended.
The cycle is designed for use by one person, with the seating position adjusted to suit their
height (see the “Basics / Seating position” chapter).
The use of child seats, child trailers and other bicycle trailers (load and dog trailers) is not
permitted for vehicles in vehicle categories 0 and 6. If a child seat or a trailer is used with
a vehicle of category 2, 3, 4 or 5, the driver must comply with the intended use of catego-
ry 2. The specified instructions for use remain valid for category 1.
The use of child seats, child trailers and other bicycle trailers is not permitted for:
Vehicles with a carbon rear triangle, unless it has a special mount for securing the
trailer hitch
S-pedelec cycles
Children’s and junior bikes with size 12", 16", 20" or 24" wheels.
For further information, please read the chapter "Safety / Notes on bringing along chil-
dren" and pay attention to special instructions for use on your vehicle. Contact your dealer
before using child trailers or child seats. Racing bikes and fitness bikes are designed solely
for use on roads and paths with a smooth asphalt, concrete or paved surface. Any use on

unsurfaced paths may cause the cycle to break down. The installation of a luggage rack,
child seat or trailer is not permitted.
A racing bike / fitness bike is defined as a cycle
with drop handlebars (racing bike) or flat handlebars (flat bar on a fitness bike)
with narrow tyres with very little or no tread
with a rigid frame
which requires a stretched out seating position, as in cycle sports

xHave the seating position correctly adjusted by your dealer.
CAUTION
Limited ability to reach controls due to an incorrectly adjusted seat-
ing position.
Risk of accident and injury!
xHave the seating position correctly adjusted by your dealer.
The optimum seating position depends on the size and shape of the cycle frame, the size
of the rider, and how the handlebars and saddle are adjusted. Optimum seating position
adjustments require expertise.
The optimum seating position can also depend on how the cycle is used, e.g. primarily for
sports.
The main characteristics of an optimum seating position are:
When one pedal is up, the arms and the top knee are all at a 90° angle. The lower leg
is slightly bent (see “Illustr.: Optimum seating position (A)”).

about how to put the cycle into use.
4.1 Quick releases
NOTE
Material breakage due to handling components incorrectly.
Risk of damage!
xOnly pull a quick release lever by hand. Never use tools or other
implements to pull the lever.
A quick release is a clamping device that al-
lows cycle components to be fitted, removed
or adjusted quickly and without tools. An ec-
centric mechanism creates tension when the
quick-release lever is pulled. Quick releases
consist of two main elements: the quick-re-
lease lever and the quick-release adjusting
nut.
Quick releases often have two additional
springs and sometimes a separate pulley un-
der the lever.
If no tension is created when the quick-re-
lease lever is operated, the quick release
must be readjusted.
xScrew the quick-release adjusting nut
clockwise onto the axle until you notice that tension is created when you pull the
quick-release lever.

4.2.1 Adjusting the saddle height
The cycle may be equipped with a rigid seat post or a
telescopic seat post, depending on the model. Both
types of seat post can be fastened using either a seat
post clamp with a clamp bolt, or a quick-release seat
post clamp. The seat post clamp allows the height of
the saddle to be adjusted.
For some cycle models, it is not possible to completely
lower the seat post into the seat tube. If the seat post
hits an obstacle in the seat tube, pull the seat post up-
wards approximately 5 mm/0.2" from this point and
fasten it there.
If you are unable to achieve an optimum seating posi-
tion in this way, have a shorter seat post installed by
your dealer if necessary.
xFor more information about telescopic seat posts, read the “Telescopic seat post”
chapter.
If your cycle has a seat post clamp with a clamp bolt:
1. Hold the saddle firmly and loosen the clamp bolt by turning it anticlockwise until the
seat post can be moved in the seat tube.
2. Pull the seat post out to the desired height.
xFollow the minimum insertion depth and minimum pull-out height specifications.
3. Tighten the clamp bolt by turning it clockwise to fasten the seat post clamp.
xObserve the permitted torque (see the “Safety / Notes on torques” chapter).
4. Check whether the saddle is correctly positioned. It must not twist.

Risk of accident and injury!
xSwitch on lighting in poor visual conditions and in the dark.
WARNING
Inattention on the road due to switching on lighting.
Risk of accident and injury!
xDo not switch on lighting while riding. Always stop to switch on
the lighting.
WARNING
Certain standard pre-assembled lighting devices can develop a
good deal of heat, especially when stationary, and cause burns if
touched.
Risk of injury!
xDo not touch the lighting during or shortly after operation to
avoid burns.
In order to ride on the road, lighting and reflectors must meet national and regional regu-
lations.
xRefer to and follow national and regional regulations on lighting equipment.
xAcquaint yourself with these before your first ride. Retrofit your cycle to meet the
regulations if necessary. Contact your dealer about this.
Lighting consists of a headlamp, rear lamp and reflectors, and ensures better visibility in
poor visual conditions and at night.
The cycle may be equipped with hub dynamo fixed lighting or battery-powered clip-on
lighting, depending on the cycle model.
Cycle Basic adjustments
55
4.7.1 Hub dynamo
The hub dynamo, to which the headlamp is connected, is located in the front wheel hub.
The rear lamp is linked to the headlamp. The hub dynamo supplies the lighting with power
as soon as the front wheel is turned.
With a hub dynamo, the lighting is generally switched on directly from the headlamp or
from the handlebars. When the switch is operated, the rear lamp is switched on along
with the headlamp.
xSwitch the lighting on and off by operating the switch.
Depending on the lighting model, there may be an integrated light sensor. In automatic
mode, the headlamp and rear lamp are switched on and off automatically depending on
the light conditions.
xAdjust to automatic mode to switch on the light sensor.
Depending on the lighting model, the rear lamp on your cycle may have a standing light
feature which allows the rear lamp to remain lit for several minutes even when you stop
riding. This feature does not need to be switched on separately.
There are various types of headlamp with different switch options. Have
your dealer explain how they are operated and how they function.
4.7.2 Battery-powered and rechargeable lighting
Depending on the lighting model, the headlamp and rear lamp may be equipped with dif-
ferent switches and need to be operated independently of each other.
xSwitch the lighting on and off by operating the relevant switch.
xRefer to the information enclosed by the manufacturer about operating and fitting
battery-powered and rechargeable lighting.

4.7.3 Headlamp
1. Switch on the headlamp.
2. Adjust the headlamp so that, at a dis-
tance of 5 m/16.4 ft in front of the head-
lamp, the light beam reaches a point only
half as high as at its starting point (see
“Illustr.: Adjusting the headlamp”).
xAn incorrectly adjusted headlamp can
dazzle other road users.
4.7.4 Rear lamp
A rear lamp must be installed in an easily visible location at the back of the cycle.
xCheck that the rear lamp is functional and unobscured before riding off.
4.7.5 Reflectors
Reflectors must be installed in an easily visible location on the cycle and must not be ob-
scured. Generally, reflectors are located on the pedals, the tyres, the rear lamp and the
headlamp.
xCheck that all reflectors are undamaged and visible before riding off.
4.8 Suspension
This chapter contains information for the following cycle categories:
WARNING

5 Brake
5.1 Basics
The cycle is equipped with at least two independent brakes. Depending on the cycle mod-
el, the following brakes may be installed:
Coaster brake
Rim brake
Disc brake
5.1.1 Coaster brake
Cycles with hub shifting systems and cycles
without gear shifting systems are frequently
equipped with a coaster brake. This is inte-
grated in the cycle’s rear wheel hub and oper-
ated using the pedals (see “Illustr.: Coaster
brake”).
5.1.2 Brake lever
The brakes are operated using the brake levers. Force is transmitted mechanically or hy-
draulically. In the case of a mechanical design, the force from the brake lever is transmit-
ted to the brake via a cable. In the case of a hydraulic design, the force from the brake lever
is transmitted to the brake via brake lines which contain brake fluid.
If the cycle is equipped with just one brake lever, this operates the front brake. The rear
brake is the coaster brake.
If the cycle is equipped with two brake levers,
the left-hand brake lever is generally for the
front brake while the right-hand brake lever is
for the rear brake (see “Illustr.: Brake lever ar-
rangement”).
xNote that the arrangement of the brake
levers may vary. Familiarise yourself with
the brake lever arrangement before set-
ting off. Contact your dealer if you would
like to have the brake lever arrangement
changed.
Illustr.: Coaster brake (example)

5.1.2.1 Disc brake
The brake discs are fastened to the wheel
hubs, with the corresponding brake calliper
fastened to the frame or front fork (see “Illus-
tr.: Disc brake”). The brake pads are located
inside the brake calliper. When the brake lever
is operated, the brake pads are pressed
against the brake disc and brake the wheel.
5.1.2.2 Rim brake
Rim brakes are fastened to the front fork or rear frame. When operated, the brake block
holders are pressed against the braking surface of the rim sidewall to brake the wheel
(see “Illustr.: Mechanical rim brakes” and “Illustr.: Hydraulic rim brake”).
Depending on the brake design, mechanical rim brakes may be equipped with a brake
force modulator. The brake force modulator partially regulates the brake lever force at the
front and prevents the front wheel locking up. The brake force modulator is installed be-
tween the brake lever and rim brake.

5.2 Operation
WARNING
Risk of overturning due to pulling the front brake.
Risk of accident and injury!
xUse the front brake lever carefully at high speeds to prevent
overturning.
xAlways brake using both brakes simultaneously for optimum
brake power.
xAdapt the braking force from the brakes to suit the riding situ-
ation, road conditions and weather so that you avoid locking up
the wheels.
xUse the rear brake carefully when cornering to prevent the rear
wheel locking up.
WARNING
Longer braking distance due to reduced brake power in the wet.
Risk of accident and injury!
xAdapt your riding style and speed to suit the weather and road
conditions.
5.2.1 Operating the brake lever
xTo operate a brake lever, pull it towards
the handlebar grip with your fingers.

5.2.2 Operating the coaster brake
WARNING
No coaster brake action where the chain has dropped off the chain-
ring.
Risk of accident and injury!
xIf the coaster brake has no effect, brake carefully using the front
brake lever and also the rear brake lever if applicable.
The coaster brake only functions when riding forwards. The coaster brake
is operated most effectively if the pedals are in a horizontal position with
the downward force acting on the rear pedal. Operate the brake levers when
rolling backwards.
The coaster brake is operated by back-pedal-
ling, and brakes the rear wheel (see “Illustr.:
Operating the coaster brake”).
xEnsure that the crankset is functional, as
the braking force is transmitted via the
chain.
xTo operate the coaster brake, pedal coun-
ter to the direction of travel.
5.3 Bedding in disc brakes
New brakes must be bedded in before they can reach their full brake power.
xKeep off the road while bedding in the brakes.
xBrake in a controlled manner to prevent the wheels locking up.
xOperate both brake levers simultaneously.
xBedding in consists of around 30 short periods of braking. Brake from around
25 km/h/15.5 mph down to a stop. The bedding-in process is complete when a con-
sistent brake action is produced upon steadily operating the brake lever.
Illustr.: Operating the coaster brake (example)
Cycle Brake
63
5.4 Maintaining braking force
Diminished brake action in disc brakes due to the brake system overheating is known as
“fading. When the temperature at the point of contact between the brake pads and brake
disc rises, e.g. due to continuous braking, the brake power drops.
xAvoid long periods of continuous braking.
xAllow the brake pads to cool down regularly.
xDo not use the cycle if the brake power is reduced due to warming.
xOnly use the cycle again once full brake power is restored.
5.5 ABS system
It is possible that an ABS system is installed on your vehicle.
The ABS system works in such a way that when the brakes are applied, sensors on the
front wheel detect the critical tightening pressure, limit it and thus stabilise the vehicle.
Once the vehicle has been stabilised, the ABS system continuously builds up the applica-
tion pressure of the brakes until the front wheel is brought back to the locking limit. If the
front wheel locks again, the pressure is released again. The process is repeated to keep
the front wheel at the limit of adhesion at all times, thus keeping the friction between the
tyres and the road surface at an optimum level.
All further information on the ABS system can be found in the additional instructions sup-
plied.

5.6 Adjustments
The grip width must be custom-adjusted so that the brake lever can be op-
erated easily and safely (see the “Basic adjustments / Brake lever / Adjust-
ing the grip width” chapter).
5.6 .1 Adjusting the brake cable tension in mechanical brakes
WARNING
Loss of brake action due to worn brake pads and cables.
Risk of accident and injury!
xReplace worn brake pads and cables.
xIf you lack the necessary expertise and the tools required to re-
place these, contact your dealer.
With mechanical brakes, minor brake pad wear is offset via the brake cable tension.
Changing the brake cable tension alters the distance between the rim and the brake block
holders. The position of the lock nut and knurled screw may vary depending on the cycle
model.
1. Loosen the lock nut by giving it one turn
anticlockwise.
2. To increase the cable tension, gradually
turn the knurled screw anticlockwise until
the distance between the brake block
holders and the rim is 1–2 mm/0.04–
0.08" on each side.
xEnsure that the brake block holders
meet the rim simultaneously on both
sides.
xEnsure that the wheel turns smooth-
ly (see the “Wheels and tyres / Rims
and spokes” chapter).
Illustr.: Lock nut and knurled screw position

3. Tighten the lock nut by turning it clockwise.
xIf the brake cannot be adjusted through the cable tension, have the brake adjust-
ed by your dealer.
5.6.2 Adjusting the pressure point
With hydraulic brakes, minor break pad wear
is offset via the pressure point adjustment
screw (see “Illustr.: Adjustment screw posi-
tion”). The adjustment screw is generally lo-
cated on the brake lever. Brakes without an
adjustment screw have the distance adjusted
automatically.
The distance between the rim and brake pad
is increased or decreased depending on the
turning direction.
xFor rim brakes, gradually turn the adjust-
ment screw until the distance between the rim and each brake pad is 1–2 mm/0.04–
0.08".
xEnsure that the brake block holders meet the rim simultaneously on both sides.
xEnsure that the wheel turns smoothly (see the “Wheels and tyres / Rims and
spokes” chapter).
xFor disc brakes, gradually turn the adjustment screw until the desired pressure point
is reached.

6 Derailleur shifting system
6.1 Basics
Usually all modern cycles have a gear shifting system installed; this depends on the cycle
model. Exceptions include children’s bikes, which may only have one gear depending on
the model.
The gear shifting system on a cycle consists of a variable gear unit and the corresponding
controls. As a result, the power provided by the rider is adapted to suit the riding speed
and route conditions.
A derailleur shifting system consists of 1 to 3 chainrings on the crankset and 6 to 12
sprockets on the rear wheel (see “Illustr.: Components of a derailleur shifting system”).
Separate controls on the right and in some cases the left-hand side of the handlebars are
generally used to shift sprockets and chainrings (see the “Derailleur shifting system / Op-
eration” chapter).
Adjustments to the gear shifting system require expertise.
xIf you lack the necessary expertise and the tools required, contact your dealer.
6.1.1 Mechanical derailleur shifting system
xWhen shifting gear, pedal only gently.
The theoretical number of gears is deter-
mined with a “chainrings × sprockets” calcu-
lation (see the “Derailleur shifting system /
Basics / Gear combinations” chapter).
The smaller the sprocket, the higher the se-
lected gear and the lower the cadence.
The larger the sprocket, the lower the select-
ed gear and the higher the cadence.
The smaller the chainring, the higher the ca-
dence.
xUse a low gear on inclines.
xUse a high gear for higher speeds on flat
routes.

6.1.2 Electronic derailleur shifting system
An electronic derailleur shifting system is powered by a rechargeable battery which pro-
vides electricity for the front and rear derailleurs. It functions the same way as a mechan-
ical derailleur shifting system. The shifter buttons can be pressed in quick succession. The
shifting system registers how many times they have been pressed, then moves the chain
quickly and precisely. The shifting system automatically prevents an excessively crossed
chain line.
The cycle, generally a racing bike or MTB, may have an electronic shifting
system depending on the model.
Gears are shifted up or down by pressing the relevant shift lever. The electronics ensure
that the gears are changed quickly.
xContact your dealer for further information and if you have any questions, or refer to
the manual enclosed with the electronic derailleur shifting system.
6.1.3 Gear combinations
NOTE
Incorrect use of gear combinations.
Risk of damage!
xNever combine the small chainring with the smallest sprockets
or the large chainring with the largest sprockets.
CycleDerailleur shifting system
68
With incorrect gear combinations, a crossed
chain results in increased wear on the chain-
rings, sprockets and chain.
Proper use only allows for certain gear com-
binations (see “Illustr.: Gear combinations”).
xUse the gear combinations in such a way
that the chain runs parallel to the direc-
tion of travel.
xUse the smallest chainring on inclines
and the largest chainring for higher
speeds on flat routes.
xIf you are unsure about operating the
gear shifting system, have your dealer
give you instructions.
6.2 Operation
WARNING
Inattention on the road.
Risk of accident and injury!
xFamiliarise yourself with the features of the gear shifting sys-
tem before your first ride.
xOnly operate the gear shifting system if it will not take any of
your attention off the road.
xStop if you cannot operate the gear shifting system safely, e.g.
in the event of a malfunction.

xAlways start riding in a low gear (lower third of the available
gears), e.g. at maximum gears 1-3 if 9 gears are available.
xIf you are not familiar with gear shifting systems, have your dealer explain how the
shifting system is operated.
6.2 .1 Shifting sprockets
The arrangement of the shift levers (top or bottom of the handlebars) and their operation
may vary depending on the model. The gear-shifting control for the sprocket cassette is
located on the handlebars, to the right (see “Illustr.: Handlebar control for shifting sprock-
ets and chainrings”).
xTo shift onto the next largest sprocket, press the lower shift lever.
xSome models offer the possibility of shifting down multiple gears at once. To do
this, press the shift lever further.
xTo shift onto the next smallest sprocket, press the upper shift lever.
xSome models offer the possibility of shifting up a gear by pulling the shift lever in
the opposite direction with your index finger.

ter as well.
6.2.5 Operating the shift levers on a racing bike
Racing bikes with curved handlebars are usually equipped with a racing-bike shift brake
arm. The racing bike’s shift levers are built into the brake handle. Depending on the model
of the gear shifting system, gears may be shifted by moving the brake lever or by operat-
ing shift levers. On straight handlebars, the shift levers are located underneath the han-
dlebars as with other types of cycle; see the “Derailleur shifting system” chapter.
Ask your dealer how the shift levers are operated. Keep off the road while
you practice shifting gears to familiarise yourself with how the shift levers
function.

Cycle Pinion gearbox
83
8 Pinion gearbox
A Pinion gearbox is a bottom bracket shifting
system. A Pinion gearbox can be used with a
chain or a belt drive (not illustrated). The Pin-
ion gearbox has a twist-grip control fastened
to the handlebars for shifting gears. In a Pin-
ion gearbox, the chain is adjusted with a chain
adjuster (see “Illustr.: Pinion gearbox with
chain drive”) or with movable fork ends (not il-
lustrated). For belt tensioning, see the “Belt
drive / Checking the belt tension” chapter. The
Pinion gearbox is an oil-bath gearbox (see the
“Pinion gearbox / Oil change” chapter). It is not
possible to use a coaster brake with a Pinion
gearbox.
8.1 Before every ride
WARNING
Component failure.
Risk of accident and injury!
xObserve the maximum rider weight limit of 110 kg/243 lbs (in-
cluding luggage and/or backpack).
xOnly use your Pinion gearbox cycle in ambient temperatures be-
tween –15 °C and 40 °C/5 °F and 104 °F.

WARNING
Chain or belt motion while the crank is stationary.
Risk of accident and injury!
xBefore every ride, make sure that the sprockets and rear wheel
hub can freewheel smoothly.
xTurn the crank backwards. The chain must not revolve when the
sprockets and rear wheel hub are freewheeling.
xStop if damage occurs to the Pinion gearbox or unusual noises
are produced.
8.2 Shifting gears with a Pinion gearbox
Note that the shifting behaviour of a Pinion gearbox, both with a chain and
with a belt drive, is different to that of a derailleur shifting system. Keep
off the road while you familiarise yourself with the Pinion gearbox and the
change in shifting behaviour.
The marking (“>>”) on the fixed part of the twist-grip control shows the selected gear, for
example between 01 and 18.
xTo shift into a higher or lower gear, first move the twist-grip control slightly in the
direction you want to shift, then quickly shift in the desired direction.
It is possible to shift through multiple gears at once, such as from 02 to 06.
Gears can be shifted while at a standstill and while the crank is stationary or turning
backwards.
There is limited potential for shifting down under load, for example from 18 to 17.
To protect the Pinion gearbox, gears are not shifted when the pressure on the
crank or pedal is too strong, such as when riding out of the saddle.
xOnly shift down when there is not a heavy load on the crank or pedal.
Cycle Pinion gearbox
85
There is potential for shifting up under load, for example from 02 to 03.
Exceptions to this are gear changes from 06 to 07 and from 12 to 13, as the gear-
box needs to double-shift for these gear changes.
xOnly shift from 06 to 07 or from 12 to 13 when there is not a heavy load on the crank
or pedal.
It is not possible to shift directly from the lowest gear to the highest or from the high-
est gear to the lowest.
xIf the gears no longer shift precisely after running in or after longer use, contact your
dealer.
8.3 Troubleshooting
A Pinion gearbox generally runs quietly with no disturbing noises. If any
noises are produced and the gears shift properly, then the noises have an-
other cause.
Troubleshooting when using a Pinion gearbox
Fault Possible cause Solution
With a belt drive
Grinding noises Belt Alter the belt tension
Belt tension varies in the
course of a revolution
Front pulley is not centred,
chainring bolts do not hold the
front pulley central

9 Belt drive
In addition to the commonplace chain drive, there are also belt drives available for cycles.
xIf you lack the necessary expertise and the tools required to adjust or maintain a belt
drive, have the drive checked and adjusted by your dealer.
9.1 Belt drive structure
A belt drive consists of a front and a rear pul-
ley, plus a belt which may be made from vari-
ous plastics depending on the belt model. To
prevent the belt running off the pulleys, each
pulley has a side flange. On the front pulley,
the side flange is located on the outside. On
the rear pulley, the side flange is located on
the inside. Belt drives are compatible with hub
shifting systems and coaster brakes, but not
with derailleur shifting systems.
9.2 Using the belt drive
NOTE
Damage to the belt due to incorrect handling.
Risk of damage!
xEnsure that the belt is not creased, twisted, bent backwards,
turned inside out, tied or used as a strap wrench.
xDuring fitting, the belt must not be rolled up with the front pul-
ley chainring or levered on e.g. with a screwdriver.
For belt drives, the force applied by the rider is transmitted via a belt. A cycle with a belt
drive can be used in all cycling-friendly weather conditions.

Cycle Belt drive
91
9.3 Checking the belt tension
In order for the belt drive to function properly,
the belt needs to be correctly tensioned. Have
the belt tension regularly checked by your
dealer.
9.4 Belt drive wear
To minimise wear with a belt drive, it is important for the belt to run parallel between the
side flanges. Depending on the model of the belt drive, there should be
a maximum deviation of 3 mm/0.1" measured at the centre of the belt’s running
surface
and/or a maximum angular misalignment of 0.5° between the pulleys.
xIf you find wear on the belt drive but you lack the necessary expertise and the tools
required to replace it, have the belt drive or worn parts replaced by your dealer.
9. 4.1 Visually inspecting the belt for wear
The belt is subject to a certain degree of wear, depending on distance travelled and riding
conditions.
xVisually inspect the belt regularly for signs of wear.
If, for example, you find pointed, torn or miss-
ing teeth (see “Illustr.: Belt wear), then the
belt is worn.

10 Wheels and tyres
The wheel consists of a hub, sprocket cas-
sette, sprocket or pulley, and, if applicable, a
brake disc, spokes and a rim. Tyres are fitted
to the wheel rim. Depending on the cycle
model, the tyre may contain an inner tube.
The front tyre is part of the front wheel and
the rear tyre is part of the rear wheel.
If an inner tube is used, rim tape is placed
on the rim to protect the inner tube from
the rim surface and the spoke nipples.
If no inner tube is used, “tubular” tyres
are used for racing bikes or UST (univer-
sal system tubeless) tyres for MTBs.
Wheels are exposed to considerable loads due
to the weight of the rider and luggage, as well
as bumps in the road.
xHave the wheels checked and re-centred
by your dealer after breaking in the cycle
(no longer than 300 km / 186 mi of riding, 15 hours of operation or 3 months, which-
ever comes first).
xCheck the wheels regularly after breaking in.
xIf you lack the necessary expertise and the tools required, have your dealer check the
wheels and centre them if necessary.

CycleWheels and tyres
96
The tyres allow the cycle to grip the road, transmit the drive and brake forces to the road
surface, and provide cushioning when the road is uneven. Various types of tyre may be
fitted depending on how the cycle is used.
Tyre size is indicated on the sidewall of each tyre. A variety of specifications may be re-
corded here, such as:
The ETRTO size, which is given in millimetres. If 52-559 is indicated on the tyre, then
the inflated tyre is 52 mm wide with an internal diameter of 559 mm. (ETRTO stands
for the European Tyre and Rim Technical Organisation).
The size in inches. If 26 × 2.35 is indicated on the tyre, then the inflated tyre is 2.35"
wide with an internal diameter of 26".
With the exception of tubular tyres and UST tyres, the tyre and rim alone are not airtight.
An inner tube is used to keep air inside the tyre, and this is filled via a valve.
10.1.1 Valve types
Cycles may be equipped with one of the following valve types (see “Illustr.: Valve types”):
Presta valve (PV): secured with a tappet
in the valve, rim hole 6.5 mm/0.26".
Dunlop valve (DV): secured with a union
nut, rim hole 8.5 mm/0.33".
Schrader valve (SV): secured with a tap-
pet in the valve, rim hole 8.5 mm/0.33".
All three valve types have a valve cap to pre-
vent the valve getting dirty.

10.1.2 Tyre pressure
WARNING
Inner tube blow-out or tyre jumping off the rim due to excessively
high tyre pressure.
Risk of accident and injury!
xObserve the tyre pressure.
xUse a pump with a pressure display when inflating the tyres.
NOTE
Damage to the inner tube due to insufficient tyre pressure.
Risk of damage!
xDo not ride over sharp edges if the tyre pressure is too low.
xObserve the tyre pressure.
xUse a pump with a pressure display when inflating the tyres.
Tyre pressure is indicated on the sidewall of the tyre. The tyre pressure is given in bar or
psi (pounds per square inch). See the “Tyre pressure conversion” table.
The lower tyre pressure limit is suitable for light riders and uneven ground, and provides
more comfortable suspension with greater rolling resistance. The upper tyre pressure
limit is suitable for heavy riders and even ground, and provides low rolling resistance with
less comfortable suspension.
If there is an indication of the tyre inflation pressure on the rim in addition to the tyre side
wall, the lower of the two values determines the maximum tyre inflation pressure.
xAlways ride with the prescribed tyre pressure.
xCheck the tyre pressure regularly.
xInflate the tyres with air to at least the lower tyre pressure limit and no more than the
upper limit.
xUse a pump with a pressure display when inflating the tyres.

10.2 Rims and spokes
Spokes with uniform tension are required in order for a wheel to run true. The tension of
individual spokes may be altered by riding too quickly over obstacles such as kerbs, or if a
spoke nipple comes loose. Wheel trueness and rim stability are reduced when individual
spokes are damaged or no longer taut.
WARNING
Risk of falling due to locked up rim brakes or wobbly wheels in the
event of rim run-out.
Risk of accident and injury!
xOnly use true-running wheels.
xHave loose spokes tensioned by your dealer.
xHave your dealer centre untrue wheels immediately.

lease axles, thru-axles or conventional axles with hub axle nuts.
xIf you lack the necessary expertise and the tools required to adjust quick-release
axles, contact your dealer.
The cycle may be equipped with conventional
thru-axles, lever-type thru-axles or quick-re-
lease axles. The axles can be replaced with
anti-theft axles.
Axles pass through the wheels and are fas-
tened between the fork ends of the cycle. The
fork ends may be open or closed depending
on the front fork model. These have different
fitting and removal methods.
There is a large variety of fastening systems
on the market. Have your dealer demonstrate
and explain how the fastening systems on
your cycle function.
Thru-axles and quick-release ax-
les can be fitted with anti-theft
devices or replaced with axles
that feature integrated anti-theft protection. Wheels may be secured in var-
ious ways depending on the model:
Some models cannot be unfastened while the cycle is in an upright position.
With some models, a dedicated tool is required to loosen the hub axle nut or quick-re-
lease adjusting nut.

11.3 Adjustments
11.3.1 Adjusting the cable tension
If your cycle has a mechanical remote control:
The cable tension for the telescopic seat post remote control must be adjusted in the
event of a malfunction, for example if the saddle height cannot be adjusted or if the saddle
height changes despite not operating the lever or button.
xRefer to information from the manufacturer about adjusting the cable tension.
11.3.2 Adjusting the extension speed
The extension speed for the telescopic seat post is generally adjusted using the speed
adjustment screw on the remote control. The extension speed is reduced or increased de-
pending on the turning direction.
xRefer to information from the manufacturer about adjusting the extension speed.
11.3.3 Telescopic seat post remote control position
The position of the telescopic seat post remote control must be custom-adjusted so that
the lever or button can be operated easily and safely (see “Illustr.: Remote control posi-
tion”).
xIf you lack the necessary expertise or the tools required, have your dealer adjust the
remote control position to suit your needs.
3. Loosen the remote control screw by
turning it anticlockwise.
4. Position the remote control so that the
lever or button is easily accessible while
riding.
5. Tighten the remote control screw by
turning it clockwise.
11.3.4 Adjusting a pneumatic telescopic seat post
Air pressure influences factors such as the extension speed and the force that must be
exerted in order to lower the telescopic seat post. The air pressure inside the pneumatic
telescopic seat post is pre-set by the manufacturer and only needs to be adjusted in the
event of a malfunction.
xHave the telescopic seat post adjusted by your dealer.

Cycle Suspension
109
12 Suspension
This chapter contains information about the basics of suspension elements, as well as
their adjustment and operation.
If suspension elements are too soft, they will no longer provide cushioning against bumps
and the suspension will bottom out.
Suspension elements must be adjusted or tuned to prevent bottoming out. If a suspension
element frequently bottoms out, it (and often the frame too) will become permanently
damaged.
xIf you lack the necessary expertise and the tools required for the adjustments, have
suspension elements adjusted by your dealer.
12.1 Suspension seat post
Depending on the cycle model, the cycle may
be equipped with a suspension seat post.
Suspension seat posts increase comfort and
safety when riding over uneven ground. The
suspension seat post must be adjusted to
the rider’s body weight. This requires exper-
tise, and it may be necessary to replace the
springs.
12.2 Suspension fork and rear suspension
12.2.1 Basics
Depending on the cycle model, the cycle may be equipped with a suspension fork and/or
rear suspension.
Illustr.: Suspension seat post (example)

CycleSuspension
110
Suspension forks absorb impacts to the front
wheel and increase comfort as well as safety
when riding over uneven ground. The suspen-
sion fork must be tuned to the intended use
and the rider’s weight.
Rear suspension, which is installed centrally
between the front and rear frame, absorbs
impacts to the rear wheel and increases com-
fort as well as safety when riding over uneven
ground. The rear suspension must be tuned
to the intended use and the rider’s weight.
Rear suspension increases comfort when rid-
ing over uneven ground.
xIf your cycle is equipped with adjustable
rear suspension, refer to the adjustment
information enclosed by the manufacturer.

12.2.2 Operation
NOTE
Increased wear due to lockout use.
Risk of damage!
xOnly use the lockout on even roads.
xOnly use the lockout if it improves handling.
xRefer to the information enclosed by the manufacturer about operating suspension forks.
xTo lock the suspension fork, turn the knob anticlockwise until it stops.
xTo unlock the suspension fork, turn the knob clockwise until it stops (see “Illustr.: Sus-
pension fork lockout control”).
xCheck whether the rear suspension can be locked. If necessary, ask a professional
how the rear suspension is locked and unlocked.
Illustr.: Suspension fork lockout control (top view, example).
On models with a mechanical suspension element:
xTo increase the spring preload and so adjust the Sag to a lower level, turn the knob on
the suspension fork or rear suspension in the “+” direction (see “Illustr.: Suspension
fork knob”).
xTo reduce the spring preload and so adjust the sag to a higher level, turn the knob on
the suspension fork in the “–” direction.
xIf you lack the necessary expertise and the tools required to optimally adjust the sag,
have the suspension adjusted by your dealer.
CycleSuspension
112
Illustr.: Suspension fork knob (top view, example).
On models with air chambers:
xTo adjust the spring preload, increase or reduce the air pressure in the suspension
fork.
xTo increase or reduce the suspension fork air pressure, you will need a dedicated
damper pump.
xIf you lack the necessary expertise and the tools required for the adjustments, have
suspension elements adjusted by your dealer.
Cycle Suspension
113
12.2.3 Adjustments
The following adjustment options are generally available:
Compression and rebound
Sag (compression under body weight)
Lockout (suspension locking feature)
12.2.3.1 Compression and rebound
Adjusting the compression and rebound influences the damping or response behaviour of
the suspension fork or rear suspension. The ratio between compression and rebound is
crucial. Depending on the cycle model, the suspension may only be equipped for rebound
adjustment. The ratio between compression and rebound is determined by the condition
of the road. A correctly adjusted ratio ensures optimum contact between the wheels and
the ground.
xHave the compression and rebound adjusted by your dealer.
12.2.3.2 Sag
Sag is the amount of compression caused by the rider’s body weight. Depending on the
model of the suspension fork or rear suspension, and depending on the intended use, the
Sag is adjusted to a value between 15 % and 40 % of the total suspension travel.
Sag is influenced by the spring preload. When the sag is optimally adjusted, the suspen-
sion will compress by 15 % to 40 % of its travel when the rider sits on the cycle.
The sag is determined by the spring preload or by the adjustable air pressure in the sus-
pension fork or damper. The spring preload or the air pressure therefore determine the
stiffness of the suspension and whether the chassis is hard or soft.
xHave your dealer adjust the suspension fork or rear suspension to your body weight
and riding style.
Have your dealer adjust the suspension fork / damper sag to suit your body
weight and riding style. This is usually dealt with through air pressure or by
replacing suspension elements.
Cycle
Suspension
114
12.2.3.3 Lockout
The lockout feature locks the suspension fork. This can reduce bob or squat in the front
fork, e.g. where the suspension sinks when pedalling hard.
Depending on the cycle model, the rear suspension may also be equipped with a lockout
feature.
Bumps cause the suspension fork to compress slightly even when locked.
This is for technical reasons and protects the front fork against damage.

the cycle forwards and backwards. The
fork stem must not move in the head
tube as you do this.
xIf there is still play in the headset,
repeat steps 1 to 5.
7. Check how freely the handlebars move. If
the steering is heavier than before, then
the headset adjustment screw is too tight.
Start again at step 1 and turn the inner
adjustment screw a fraction anticlockwise.
8. Check whether the handlebar stem is secure by fixing the front wheel in place be-
tween your legs and attempting to turn the handlebars relative to it.
9. Check the handlebar position after adjusting the headset (see the “Basic adjust-
ments / Handlebars and handlebar stems / Aligning the handlebars” chapter).

xHave the rim checked by your dealer.
Especially with hollow chamber rims and rims made of composite
materials and aluminium, damage can occur that is not visible.
xSqueeze the spokes together gently with your thumb and fingers, checking whether
the tension is the same for all spokes.
xIf the tension varies or spokes are loose, have the spokes tensioned by your
dealer.
14.9.2 Rim wear indicator with rim brakes
The wear indicator is a groove in the surface of the rim where the brake pads are pressed.
The wear limit is reached when the surface groove can no longer be felt, i.e. has been worn
away through braking.
xCheck whether there is a wear indicator
on the rims of your cycle (see “Illustr.:Rim
with a wear indicator”).
1. If your cycle rims have an indentation,
check whether the wear limit has been
reached.
2. Stroke your fingernail vertically across
the indentation.

2. Check the tyres for cracks and damage from foreign bodies.
3. Check whether you can clearly feel the tyre tread.
xIf a tyre is cracked or damaged, or the tread depth is too low, have the tyre re-
placed by your dealer.
The following sentence is only applicable for Europe:
xOn an S-pedelec, ensure that the profile depth does not fall below 1 mm.
4. Check whether the valves are firmly in place and tighten the lower knurled nut if nec-
essary by turning it clockwise.
5. Check whether the valves have a protective cap.
xReplace missing protective caps so that dust and dirt cannot get into the valves.
14.10 Flat tyre
A flat tyre is the most frequent cause of cycling breakdowns. A flat tyre need not end your
ride if you carry the necessary tools and a replacement inner tube or repair kit.
For detailed instructions on repairing a flat tyre, see the “Maintenance / Removing the
wheel” chapter.
14.11 Removing the wheel
Before you remove a wheel, read the “Wheels and tyres” chapter. If you lack
the necessary expertise and the tools required, contact your dealer.
xOn cycles with a derailleur shifting system, shift to the smallest sprocket in the cas-
sette at the back. This will position the rear derailleur on the outside and prevent it
hindering the removal process.
xTo facilitate wheel removal, fix the cycle in place using a suitable work stand if neces-
sary.

prevent damage to the inner tube.
14.11.6 Fitting clincher or folding tyres
When fitting a tyre, ensure that no foreign bodies such as dirt or sand get
inside and that you do not damage the inner tube.
To fit clincher or folding tyres, follow these steps:
1. Place one edge of the rim inside the tyre.
2. Press the sidewall of the tyre fully over the edge of the rim with your thumbs.
3. Insert the inner tube valve vertically through the valve hole in the rim so that it points
directly at the wheel axle.
4. Inflate the inner tube slightly so that it becomes round, and place it completely inside
the tyre.
5. Use your thumbs to press the tyre over the edge of the rim as far as it will go.
6. Push the inner tube inside the tyre with your index fingers so as not to trap the inner
tube between the tyre and the rim.
7. Work your way evenly around the circumference of the tyre from both sides.
8. Finish by giving the tyre a firm tug downwards to move the previously fitted section
down into the deep rim base.
9. Check the position of the inner tube and press the tyre over the edge of the rim (see
“Illustr.: Fitting clincher or folding tyres (A)”).
xIf this is not possible, use the blunt end of the tyre lever to move the tyre over the
edge of the rim (see “Illustr.:Fitting clincher or folding tyres (B)”).
10. Press the valve into the inside of the tyre.
11. Realign the valve if necessary.
xIf this is not possible, detach part of the tyre sidewall and realign the inner tube.
12. Move the semi-inflated tyre back and forth several times in a sideways direction to
check that the inner tube is positioned in the tyre correctly with no pinching.
13. Inflate the inner tube to the desired tyre pressure. The maximum tyre pressure is
indicated on the sidewall of the tyre.

14.11.7 Fitting UST tyres
No separate inner tube is needed with UST (universal system tubeless) tyres. The tyre and
rim are connected in such a way that no air can escape.
UST tyres may only be used with a UST rim or a UST wheel. Have UST tyres
fitted by your dealer only. Do not fit UST tyres yourself unless you have the
necessary expertise.
xOnly fit UST tyres by hand. Do not use a tyre lever.
xRemove dirt and lubricant before fitting. UST tyres must be free of dust and grease
inside and around the tyre bead.
xMoisten the tyre bead with soap or tyre fitting lubricant before fitting so as not to
damage the UST tyre.
1. Using your hands, press the UST tyre onto the rim from outside.
2. First lift one tyre bead completely over one rim flange, then the other.
3. Centre the UST tyre in the rim well.

This chapter applies to models with a coaster brake or hub shifting system.
1. Set the cycle on the kickstand.
2. Press the chain upwards or downwards
and check whether you can press it
through a distance of between 10 and
15 mm/0.4–0.6" (see “Illustr.: Chain
tension”).
xIf you can press the chain upwards or
downwards by less than 10 mm/0.4"
or more than 15 mm/0.6", or if the
chain is grinding against the all-round
chain guard, have the chain tension adjusted by your dealer.
14.16.1 Adjusting the chain tension with hub gears
1. Loosen the screw connection of the rear wheel with a suitable tool. If a coaster brake
is installed in the hub, the screw connection of the torque arm to the frame must also
be removed.
1. Tension the chain by pulling the rear wheel backwards evenly in the dropout. Make
sure that the rear wheel is aligned straight in the frame. The optimum chain tension
is achieved when you can push the chain up and down a minimum of 10 mm and a
maximum of 15 mm.
1. After adjusting the chain tension, retighten the screws on the rear wheel. If necessary,
remount the torque arm of the coaster brake on the frame.
If you do not have the necessary expertise and tools for installation, contact your dealer.

14.16.2 Chain tension in derailleur shifting systems
On cycles with a derailleur shifting system, the chain is tensioned by the chain adjuster on
the gear shifting system’s rear derailleur.
1. Set the cycle on the kickstand or fix the
cycle in place with a suitable work stand
and check whether the chain is sagging.
2. Gently press the chain adjuster forwards
and check whether it moves back by
itself (see “Illustr.: Chain adjuster on the
rear wheel”).
xIf the chain is sagging or the chain adjust-
er does not move back by itself, have the
chain adjuster repaired by your dealer.
14.16.3 Shift cables
1. Check that the outer casings and inner wires are undamaged.
2. Operate the gear shifting system and check whether the shift cables move freely.
xHave faulty shift cables replaced by your dealer.
14.16. 4 Derailleur shifting system
1. Using a suitable work stand, hang the cycle up by its frame or the seat post.
2. Turn the crankset in the direction of travel.
3. Shift through all the sprockets and chainrings (see the “Derailleur shifting system”
chapter).
4. Check that all the gears shift correctly and whether any unusual noises are produced
in the process.
xIf the gears do not shift correctly or if you hear unusual noises when shifting gear,
contact your dealer.
5. Oil the gear shifting system (see the “Cleaning / Gear shifting system” chapter).

If the cycle will not be used for a prolonged period, the following points must be noted
with regard to storage:
xClean the cycle (see the “Cleaning” chapter).
xStore the cycle in a dry, frost-free place where it is protected against major fluctua-
tions in temperature.
xTo prevent tyre deformation, store the cycle hanging by its frame.
xOn a cycle with a derailleur shifting system, shift to the small chainring at the front
and the smallest sprocket at the back to take as much strain as possible off the ca-
bles.
After storage, shift the chainring and cassette back to a gear combination
designed for riding before using the cycle again (see the “Derailleur shifting
system / Basics / Gear combinations” chapter).

1 Basics
1.1 Reading and storing the user manual
Contrary to the official standard, EPACs (electric power-assisted cycles) and
S-EPACs (speed electric power-assisted cycles) are referred to below as
pedelecs (from “pedal electric cycle”) and S-pedelecs (from “speed pedal elec-
tric cycle”) as these terms are in common use.
This user manual is a supplement. It assumes that you have read the “Cycle”
user manual. Read all the warnings and notes in this user manual carefully
before putting the pedelec or S-pedelec into operation. This user manual is an
integral part of the pedelec or S-pedelec. Store this user manual carefully so
that it is available at all times. If passing the pedelec or S-pedelec on to a third
party, include the user manual along with it.
Also refer to and follow the manuals enclosed with the pedelec/S-pedelec
drive system.
1.2 Identification of warnings
The following signal symbols and signal words are used in this user manual to warn against
personal injury or damage to property.
Warnings are intended to draw attention to possible dangers. Failure to follow a warning
may result in injury to yourself or other people, as well as causing property damage. Read
and follow all warnings.
DANGER
This warning identifies a hazard with a high degree of risk, resulting in serious
injury or death if not avoided.
WARNING
This warning identifies a hazard with a moderate degree of risk, resulting in seri-
ous injury if not avoided.
Pedelec/S-pedelec Basics

1.5 Notes on screw turning directions
NOTE
Material damage due to handling screw joints incorrectly.
Risk of damage!
xObserve the turning direction of screws, thru-axles and nuts.
xTighten screws, thru-axles and nuts by turning them clockwise.
xLoosen screws, thru-axles and nuts by turning them anticlockwise.
In the event of any deviation from this rule, the change in turning direction will
be indicated in the respective chapter. Refer to the relevant notes.
1.6 Pedelec and S-pedelec differences
1.6.1 Pedelec
The following paragraph is only applicable for Europe:
Pedelecs are cycles with an electric auxiliary motor that provides assistance up to a maxi-
mum of 25 km/h (15.5 mph) when you pedal.
Depending on the cycle model, there may be a pushing aid which can accelerate the cycle
up to 6 km/h (4 mph) depending on what gear the shifting system is in.
The following paragraph is only applicable for the USA:
Pedelecs are cycles with an electric auxiliary motor that provides assistance up to a maxi-
mum of 20 mph when you pedal. By law, pedelecs are class 1 (see the “Explanation of sym-
bols” chapter). There may be a pushing aid depending on the cycle model. How this func-
tions is described in more detail in the drive system user manual enclosed with the cycle.
Pedelecs are cycles that are legally classed as bikes in most countries. Acquaint yourself
with the national and regional regulations and classification in your country.
xFind out what category your pedelec falls into in your country. Note that regulations
vary from country to country.
xAcquaint yourself with the applicable national and regional road regulations.
xContinually acquaint yourself with changes in the content of applicable regulations.
xNote that tampering with the pedelec speed can not only have legal consequences,
but may also lead to accidents.

1.6.2 S-pedelec
The following paragraph is only applicable for Europe:
S-pedelecs are cycles with an electric auxiliary motor that provides assistance up to a max-
imum of 45 km/h (28 mph) when you pedal. Depending on the model, all-electric operation
up to a maximum of 18 km/h (11 mph) may also be possible.
The following paragraph is only applicable for the USA:
S-pedelecs are cycles with an electric auxiliary motor that provides assistance up to a maxi-
mum of 28 mph when you pedal. There may be a pushing aid depending on the cycle model.
How this functions is described in more detail in the drive system user manual enclosed
with the cycle. By law, S-pedelecs are class 3 (see the “Explanation of symbols” chapter). In
some countries, S-pedelecs are classed as motor vehicles. Acquaint yourself with the na-
tional and regional regulations and classification in your country.
Note national and regional differences with regard to:
Minimum age limits for using S-pedelecs
Driving licenses
Compulsory insurance and registration if applicable
Operating licenses
Compulsory helmet use
Provisions regarding use on bike paths, woodland trails and forest roads
xNote that tampering with the S-pedelec speed can not only have legal consequences,
but may also lead to accidents.
1.7 Differences between a pedelec/S-pedelec and bike
CAUTION
Unexpected pedelec/S-pedelec behaviour due to sharp accelera-
tion.
Risk of accident and injury!
xFrost, rain, sand or leaves on the road can lead to accidents, par-
ticularly with pedelecs/S-pedelecs that have front-wheel drive.
xUse the cycle’s gear shifting system and always ride in a low
gear.
Pedelec/S-pedelec Basics
11
The components of the electric drive are the main differences between a conventional bike
and a pedelec/S-pedelec.
Due to the significantly higher weight and change in weight distribution, a pedelec/S-
pedelec handles differently.
The drive has a significant impact on braking behaviour.
Pedelecs/S-pedelecs require more braking force. This can increase wear.
On pedelecs/S-pedelecs with a central motor, there are significantly higher forces
acting on the drive train. This increases wear.
Electrical assistance may increase riding speed. Careful riding is required as other road
users may need to adjust to the higher speed of the pedelec/S-pedelec.
The handling and braking behaviour requires appropriate expertise, as does use of the
rechargeable battery and charger.
xFamiliarise yourself with the characteristics of the pedelec/S-pedelec even if you
already have experience with electrically assisted cycles (see the “Basic adjustments /
Before the first ride” chapter).
1.8 EC certificate of conformity for S-pedelecs
The following paragraph is only applicable for Europe:
CoC = certificate of conformity
This document is enclosed with your S-pedelec and uniquely assigned to this one cycle. The
CoC confirms that the cycle corresponds to the approved type. You need the CoC to insure
the cycle, and to register it if applicable. Acquaint yourself with national and regional regula-
tions before your first ride.
Please note:
Keep the CoC in a safe place. You need it to insure the cycle. The CoC will also be required
by the buyer in the event that you sell the cycle. There is great effort and significant cost
involved in producing a duplicate CoC at a later date.
Non-EU countries:
In countries outside the European Union, the EC certificate of conformity supplied may not
be sufficient. In Switzerland, for example, separate type approval and a cycle registration
document are required.
Pedelec/S-pedelecBasics

1.9 CE marking and declaration of conformity for pedelecs
The following paragraph is only applicable for Europe:
With the CE marking on the pedelec and the declaration of conformity, the manufacturer of
your pedelec confirms that the product meets all requirements* and other relevant provi-
sions in directives 2006/42/EC, 2014/30/EC and standards ISO 4210 and DIN EN 15194,
as well as other relevant directives and standards if applicable. You can find the declaration
of conformity enclosed with your pedelec.
*Status at the time of publication.
1.10 Function
The drive only assists with riding when you are also pedalling. The amount of assistance is
adjusted automatically according to the selected gear, depending on the system or model
installed, pedal force, load and speed:
Depending on the design of your pedelec, the drive may assist up to a speed of
25 km/h (15.5 mph). The pushing aid can accelerate the cycle up to 6 km/h (4 mph)
depending on what gear the shifting system is in.
Depending on the design of your S-pedelec, the drive may assist up to a speed of
45 km/h (28 mph). The starting aid can accelerate the cycle up to 18 km/h (11 mph)
depending on what gear the shifting system is in.
In terms of the maximum speed with pedal assistance, a tolerance of 10 % is permitted and
possible when riding.
1.11 Range
The drive is an auxiliary motor. To obtain the longest possible range, the following points
must be noted:
The motor works most efficiently at a cadence of 50–80 crank revolutions/minute.
xShift to a lower or higher gear before inclines and descents to avoid excessively fast or
slow cadences.
xOperate the gear shifting system as if you were riding without assistance.
xUse the smaller gears in your gear shifting system on inclines, in headwinds and with
heavy loads.
Starting in the lowest gear increases the range.
xAlways ride in a low gear and pedal as hard as possible.
xOn models with hub shifting systems, you can shift into 1stgear while stationary.
On models with derailleur shifting systems, you should shift into the lowest gear
while you are still stopped.
Pedelec/S-pedelec Basics
13
Riding uphill reduces the range, as does frequent stopping and starting.
xShift down to a lower gear in good time before inclines.
xLook ahead and anticipate while riding so that you can avoid unnecessary stops.
Riding on unsurfaced ground reduces the range.
xWhere possible, ride on surfaced roads and paths.
A high gross weight (cycle + rider + luggage) increases energy consumption.
xDo not transport unnecessary loads.
You can get the most kilometres out of a new and fully charged battery.
Neglected cleaning and maintenance can reduce the range.
xTake care of the pedelec/S-pedelec on a regular basis and check the tyre pressure
regularly.
xContinually test the functionality of the pedelec/S-pedelec and check for wear, as well
as referring to all notes on the rechargeable battery in this user manual and in the
drive system manual.
xObserve maintenance intervals.
High average speeds reduce the range.
The stronger the assistance mode, the shorter the range.
Ambient temperatures below +10 °C/50 °F and above +40 °C/104 °F can reduce the
range.
Particularly high and particularly low ambient temperatures can permanently speed
up battery wear or even damage the rechargeable battery.
xStore the rechargeable battery at room temperature before a ride to ensure an opti-
mum temperature for use.
xRefer to the notes on storing the rechargeable battery correctly.
xDo not insert the rechargeable battery in the holder until just before the ride.
Because the range is dependent on a variety of factors such as the level of assistance,
speed, shifting behaviour, tyres and tyre pressure, age and condition of the rechargeable
battery, route profile and conditions, headwind and ambient temperature as well as the
weight of the cycle, rider and luggage, it is not possible to accurately predict the range be-
fore setting off or during a ride.
In general, however:
If the level of assistance remains the same, then the less force you need to apply to
reach a particular speed (e.g. through optimum shifting behaviour), the less energy the
drive will consume and the longer the range from the battery charge.
If all other conditions are the same, then the higher the selected level of assistance,
the shorter the range.

1.12 Road use
The following paragraph is only applicable for Europe:
Depending on the design, pedelec assistance may be effective up to a speed of 25 km/h
(15.5 mph). With an S-pedelec, the assistance is switched off at a speed of 45 km/h
(28 mph).
The following paragraph is only applicable for the USA:
Depending on the design, pedelec assistance may be effective up to a speed of 20 mph.
With an S-pedelec, the assistance is switched off at a speed of 28 mph.
xFind out before your first ride whether your pedelec/S-pedelec is equipped in accord-
ance with requirements for use on the road. Note that national and regional regula-
tions may vary. For example:

xRecharge an empty battery straight away.
Pedelecs/S-pedelecs are usually equipped with a lithium-ion (li-ion) rechargeable battery.
With proper use, li-ion batteries are safe. Lithium-ion batteries have high energy density.
For this reason, a great deal of caution must be taken when handling these rechargeable
batteries. For rider safety, reliable operation and a long service life, it is essential to note the
following:
After the first full charge, the battery can be partially charged. Partially charging the
battery will not damage it, as lithium-ion rechargeable batteries do not have a mem-
Pedelec/S-pedelecOperation
34
ory effect.
Partial charges are rated proportionally to their capacity (a charge of 50 % corresponds
to half a charge/discharge cycle).
Temperature limits must be observed for the rechargeable battery to function properly.
xRefer to the information enclosed by the manufacturer about the rechargeable bat-
tery as well as the enclosed drive system manuals.
Note that ambient temperatures below +10 °C/50 °F and above +40 °C/104 °F can
reduce the range.
Particularly high and particularly low ambient temperatures can permanently speed
up battery wear or even damage the rechargeable battery.
xThe battery is subject to a certain amount of wear. For details about the charging
cycles and the corresponding power losses, refer to the information in the system
operation manual of the associated drive system.
xIf you experience excessive power loss, e.g. operating time is significantly short-
ened, have the rechargeable battery checked by a dealer.
xNever make any alterations to the rechargeable battery yourself.
4.4.1 Safety feature
CAUTION

7 Disposal
7.1 Cycle
Do not dispose of your cycle in household waste. Take it to a municipal collection point or a
recycling centre.
Alternatively, there are also collections organised by local councils and private organisa-
tions. Contact your local council about this or refer to postal information.
7.2 Electrical elements, single-use batteries and rechargeable
batteries
Pedelecs, S-pedelecs and bikes with electric shifting systems
or electric damper systems must have all single-use and re-
chargeable batteries removed first, along with any detachable
controls containing batteries. This means the rechargeable
batteries from the drive system, displays with built-in re-
chargeable batteries, rechargeable batteries for shifting or
damper systems that are built into or onto the frame, etc. Re-
movable displays with built-in rechargeable batteries or displays that continue to offer an
active display after removal from their brackets and do not appear to have a battery com-
partment on the back side must be disposed of completely. Only externally accessible bat-
tery compartments (generally for button cell batteries) may be opened. The display housing
must not be opened to remove a fixed rechargeable battery.
Fixed rechargeable batteries in displays are generally lithium-ion batteries and therefore
hazardous waste. They must not be disposed of in household waste, and must be taken to
a municipal collection point or a recycling centre instead.
This also applies to replaced batteries which can no longer be used due to wear or a defect.
Please also refer to the “Safety notes / Rechargeable battery safety notes” chapter in the
supplementary user manual Pedelec, S-Pedelec.
Commercially available single-use batteries can be taken to a municipal collection point or a
recycling centre, and can also placed in battery collection boxes which are available in vari-
ous shops or stores.
After removing any single-use or rechargeable batteries, the remainder of the cycle is
classed as waste electrical and electronic equipment and must be sent for recycling sepa-
rately.
Your dealer, the municipal collection point or a recycling centre can assist you here.
Pedelec/S-pedelecDisposal
44
7.3 Electronic components and accessories
Replaced or defective LED headlamps, LED rear lamps or hub dynamos, as well as accesso-
ries such as bike computers or navigation devices, must also be disposed of separately.
Take parts and devices of this kind to a municipal collection point or a recycling centre.
7.4 Packaging
Any kind of packaging must be disposed of separately. Add cardboard and paperboard to
the waste paper and foils in the recyclable waste collection or ask your dealer for disposal.
7.5 Tyres and inner tubes
Tyres and inner tubes must not be disposed of in household waste.
Ask your dealer whether they take care of collection and disposal, or take these items to a
recycling centre or municipal collection point.
7.6 Lubricants and care products
Do not dispose of lubricants and care products in household waste, into the sewer system
or into the environment. They must be taken to a hazardous waste collection point.
