indicates a potentially dangerous situation. Failure to comply with
this safety instruction can result in damage to the pedelec and its
components.
This symbol indicates helpful tips, useful or important
information about the product or its additional uses. It does
not indicate a dangerous or harmful situation.
I.II The Impulse Evo / Impulse Evo Next pedelec
Your Impulse Evo / Impulse Evo Next pedelec is an EPAC (electrically
power assisted cycle). When the assist mode is switched on, the electric
motor provides assistance as long as you are pedalling. You can control
the degree of assistance, which is adjusted using various assist modes
5.5 Changing assist mode Page EN-40. The drive assistance is dependent
on the force and speed of your pedalling and the speed you are travelling.
Motor assist stops as soon as you stop pedalling and when the battery
is discharged or if you reach a speed of 25 km/h. So pedalling harder is
required if you want to travel faster than 25 km/h.

DANGER
Check that the brakes work and that the handlebars can move freely
before every ride. Do not use the bike if it is not in perfect technical
condition. If you are unsure, ask your cycle dealer to check it over.
Inspect your pedelec before every trip, and after each time it has been
transported anywhere or left unattended 4. Before every trip Page
EN-36. Components might fail if wear and damage are not detected
early enough. Should this happen whilst you are cycling, you could
injure yourself very seriously or even die. The additional power means
higher loads are applied to wearing parts on a pedelec than on a
normal cycle. Replace any worn, damaged or bent components before
using the bike again.
Do not exceed the overall weight permitted for the pedelec because
parts important for safety might fracture or fail VI.I Overall weight
Page EN-10. If this happens while you are riding the bike, severe falls
might result – with fatal consequences.
Contact your cycle dealer when wearing parts and other components
need to be replaced. We recommend having your cycle dealer assem-
ble and adjust the bike.
Otherwise components could become loose due to incorrect assembly.
If this happens whilst you are cycling, you could injure yourself very
seriously or even die. If you do have to tighten something yourself,
a full list of torque settings is in Section 12. Torque settings Page
EN-103 (strict adherence to which is a requirement).
1. General safety information
Comply with the safety and user instructions at the start of the following
sections.
DANGER
We discourage allowing children under the age of 14 years to ride
pedelecs. They may not be able to cope with the speed. Serious
accidents and falls might result.
Wear a cycle helmet. While there is no legal obligation to wear one,
you should always wear a suitable cycle helmet for your own safety. A
cycle helmet can protect you from severe injuries. Make sure that the
helmettsproperly.
Keep your hands and other body parts and clothing away from moving
parts, otherwise you can become ensnared, have a serious fall and
injure yourself.
Adaptyourridingstyletotheprevailingtracconditions,otherwise
youcouldfalloandinvolveyourselfandothersinaserious
accident. Take into consideration the longer braking distances needed
on wet or icy roads. Think ahead, anticipating the actions of other
road users and reduce your speed. Avoid sudden jerky movements of
the handlebars and braking actions. Dismount if you ever feel unsafe.
Only use the bicycle for its intended purpose V. Intended use Page
EN-9, otherwise component failure may result. Should this happen
whilst you are cycling, you could injure yourself very seriously or even
die.
EN-14 Original User Guide | Pedelec Impulse Evo / Impulse Evo Next Version 4
CAUTION
Do not open up the motor, display, battery or charger as you could
injure yourself. Parts might also be damaged beyond repair,
invalidating the warranty. Contact your cycle dealer when problems
arise.
IMPORTANT
Always park your pedelec so that it cannot tip over. Components can
be damaged if the bike tips over. If your bike is not equipped with
akickstand,onecanbettedifrequired.Pleasecontactyourcycle
dealer.
Do not clean the pedelec with a water hose or high pressure washer.
Although the components are sealed, damage to the cycle may still
result. Clean the pedelec with a soft damp cloth.
DANGER
Only use original replacement parts. Replacement parts from other
manufacturers can impair the function of your pedelec. Serious acci-
dents can result.
Ask your cycle dealer to show you how to use, and explain, the special
features of the components. Please also follow the component guides.
We recommend having your cycle dealer assemble and adjust the bike.
Otherwise components could become loose due to incorrect assembly.
If this happens whilst you are cycling, you could injure yourself very
seriously or even die. If you do have to tighten something yourself,
a full list of torque settings is in Section 12. Torque settings Page
EN-103 (strict adherence to which is a requirement).
WARNING
Do not ride in unfavourable lighting conditions (fog, rain, dusk,
darkness) without adequate lights IV.II.I Lights Page EN-8. Failure
to do so can result in accidents and serious injuries.
Always remove the battery before starting work on the pedelec. The
pedelec could switch on unexpectedly and you could be seriously
injured.
Original User Guide | Pedelec Impulse Evo / Impulse Evo Next Version 4 EN-15
2. Protection from theft, manipulation and loss
DANGER
Protect your pedelec from unauthorised access. Serious injury may
result if third parties modify components (e.g. the brakes) without
your knowledge. Inspect your pedelec before every trip, and after
each time it has been transported anywhere or left unattended 4.
Before every trip Page EN-36. If your bike is damaged, only ride it again
oncethedamagehasbeenrectied.Yourbikewillnotbereplaced
under warranty if lost or stolen.
The following measures can help you to protect your pedelec from theft
and manipulation and to recover it if it has been stolen:
Always lock the bike and battery even if you leave it for
a short while. Ideally, the lock(s) should block the wheel
powered by the motor. Do not leave the key in. To be on the
safe side, you can also remove the battery. A pedelec must
also be secured with a lock when parked outside residential
areas (e.g. in a shed or basement).
Do not park your pedelec in deserted locations –
especially for long periods. If possible, park your pedelec
in private or communal garages or individual bike lockers
which have surveillance.
Attachyourpedelectoaxedobject(suchasatree,street
lamp or fence) so that it cannot be carried away.
Quick-releasewheelsshouldbeattachedtoaxedobject
together with the frame. This prevents the wheel from
being stolen. Alternatively, the quick-release levers can be
replaced by an anti-theft device. Contact your cycle dealer if
you have questions on this.
Use a high-quality bike lock. Invest about 10% of the
purchase price of the bike in locks. Your cycle dealer will be
abletotasuitableframelockifyourbikedoesnotalready
have one. You can also use other types of bike lock. Ask
your cycle dealer for advice.
Make a note of the important details of your pedelec (e.g.
in the service book II.III Service book Page EN-6, bike
passport) and have it registered by the police. This makes it
easier to describe and identify if stolen.

DANGER
Adjusting the pedelec to your height. If the bike is not correctly
adjusted to your height, you can lose control of the bike and fall
badly.
Practise braking and riding with the assist function in a safe place
beforeventuringintotrac.If you do not familiarise yourself with the
operation and higher speed of your pedelec, you could cause a serious
accident.RideinECOmodeuntilyoufeelcondentenoughtotrythe

3.1 Attaching the pedals
1. Screw the right-hand pedal (marked ‘R’) into the right-hand pedal
crank in a clockwise direction.
2. Screw the left-hand pedal (marked ‘L’) anticlockwise into the left-hand
pedal crank.
DANGER
Screw the pedals in straight, otherwise you could damage the thread
on the pedal crank; if this happens when you are cycling, a severe fall
could result.
3. Tighten both pedals towards the front wheel to a torque of 40 Nm.
Have the police code your pedelec; the address and initials
of the owner are engraved on the frame in an encrypted
form.Codingmakestheillegalresaleofabikemoredicult
and deters thieves. A coded bike also makes it easier to
identify the owner.
Bicycle theft is often covered by household contents
insurance. Check the terms of your insurance policy as soon
as possible.
3. Beforeyourrstride
Make sure that your pedelec is adjusted to your height and ready to use.
Familiarise yourself with the basic functions of your pedelec.
DANGER
Ask your cycle dealer to show you how to use, and explain, the special
features of the pedelec and its components. Please also follow the
component guides. We recommend having your cycle dealer perform
all assembly and adjustment work. Otherwise components could
become loose due to incorrect assembly. If this happens whilst you
are cycling, you could injure yourself very seriously or even die. If you
do have to tighten something yourself, a full list of torque settings is

When you are cleaning the belt, ensure that no water enters the motor.
Water ingress can damage the motor beyond repair.
3. Leave it to dry.
3.10 Gears
The gears are operated by controls on the handlebars (gear lever, twist
grips, buttons, ...). The gear shift allows you to adjust the gears of your
bicycle, and so the transmission, to current riding conditions. On a straight
level stretch, a higher gear is sensible to achieve and maintain a higher
speed without having to pedal too much. As soon as you start going uphill,
alowergearisbenecialbecauseitisimportanttobeabletoclimbthe

Derailleur*
This system lifts the chain on to a spro-
cket when the gear is changed. The
chain must continue moving so that the
teeth of the sprocket can engage with
the chain links easily and smoothly. For
a successful gear change, therefore, you
must keep pedalling forwards, never
backwards – but at the same time pedal
lightly without force.
Hub gear*
Here the change of gear takes place in-
side the rear wheel hub. Space is very
tight inside the hub, so it is sensible to
pedal lightly when changing gear.

WARNING
Look out for deep grooves on both rims.
The rims could fracture and cause a fall.
Replace rims as soon as you detect signs
of wear. Many rims have a wear indica-
tor. If it can no longer be felt at a certain
point, the rim is worn.

3.12.1 Lockout system
Ifyoursuspensionforksarettedwitha
lockout system, it is possible to lock the
suspension. There are some riding situa-
tions where that can be useful: for ex-
ample, if you are riding up a hill or if
you are standing up from the saddle
when accelerating. To switch the sus-
pensiontoxed,turntherotarycontrol
on the right-hand side of the fork to
‘LOCK’ (or alternatively: $). To reactiva-
te the suspension, turn the control to
the ‘OPEN’ position.
LOCK/$ Suspension locked
OPEN Suspension activated
DANGER
Do not ride over rough terrain with the suspension locked. It can
damagethesuspensionforks.Abrokenforkcouldcauseyoutofallo
and seriously injure yourself.
3.11.5 Tyres
DANGER
Donoteitheroverinateorunderinatethetyres. If the air pressure
is too high, this could lead to a worst-case scenario of the tyres
bursting and you could fall. On the other hand, if the air pressure
is constantly too low, the tyre can wear prematurely. The maximum
permissible pressure is marked on the side of the tyre in bar and psi
(pounds per square inch). You can measure the tyre pressure yourself
by using a tyre gauge. Alternatively, you can contact your cycle dealer.
3.12 Suspension fork*
The suspension forks support the front wheel.
The distance travelled by the wheel between its unloaded
and fully loaded positions is called the total suspension
travel.

Inspect your pedelec before every trip, and after each time it has been
transported anywhere or left unattended. Use the following checklist to
help you.
Checklist
Type Characteristics
Frame / forks Check the frame and forks for visible warping, cracks and
damage.
Handlebars / front stem Check they are seated securely.
Check that the bell is working and attached correctly and
securely.
Saddle / seatpost Check that the quick-release skewers / through-axles (if
available) are secure.
Wheels Check the condition (damage, foreign bodies), concentricity and
pressures of the tyres.
The maximum permissible pressure is marked on
the side of a tyre in bar and psi (pounds per square
inch).Tyresshouldnotbeinatedaboveorbelowthis
pressure.
Check the valves are seated securely.
Visually inspect the rims for damage and wear.
Check that the quick-release skewers / through-axles (if
available) are secured correctly.
Chain or belt Check the chain, belt, pinions and sprockets for wear and
damage.
Brakes Check that the brake system (including brake levers) is working
and attached correctly and securely.
Visual inspection of the brake pads/disks.
3.12.2 Air system*
On some suspension forks it is possible to
alter the air pressure. You will need assis-
tance from your cycle dealer to do this, or if
youfeelcondentofdoingityourself,asus-
pension fork pump with a pressure gauge
and the suspension fork manufacturer's ins-
tallation manual. The valve with cap (e.g.
marked ‘AIR’) is usually located on the left-
hand side of the fork.
4. Before every trip
DANGER
Replace any damaged (e.g. cracks, grooves) or bent components
before using the bike again. Not doing so can lead to essential parts
failing and cause a serious fall.
Do not use the bike if it is not in perfect technical condition. If you are
unsure, ask a cycle dealer to check it over.
We recommend asking your cycle dealer to assemble and adjust the
bike. Otherwise, components could become loose due to a faulty as-
sembly. If this happens whilst you are cycling, you could injure your-
self very seriously or even die.

5. Quick-start guide
5.1 Charging the battery
If you only want to go for a quick test run, you do not need
to charge the battery. You should charge it before your first
longer cycle ride however, 10.3.1 Charging a battery
Page EN-93, because the battery is only partially charged
(production regulations dictate that batteries are supplied
partially charged by approx. 50 %).
IMPORTANT
Perform a ‘learning cycle’: You should completely run down a new,
fully charged battery once until the drive assistance stops and
without recharging it in between. In that way, the battery ‘learns’ its
capacity, and the actual capacity will agree with the level indicated on
the battery status display. As soon as the battery enters Sleep mode,
press the battery button for one second. Then the learn cycle can be
continued. Please perform a learn cycle every six months or 5,000
kilometres. If you do not repeat this from time to time, the actual
capacity of the battery will increasingly diverge from the value on the
battery status display.

6.3.3 Battery charge level and remaining range
The battery charge level and remaining range are shown in the top of the
display. A battery-shaped icon shows the remaining range, telling you how
long the Impulse Evo system can continue to assist you. The lower the
battery charge level, the shorter the black part in the battery. The range
also shows a lower value. When the charge level of the battery falls below
a minimum, motor assist also cuts out.

Measurements are taken whilst the cycle is being ridden.
The display calculates an average value from the readings
of the last 20 kilometres ridden. This value is then used as
the basis for the remaining range. So the remaining range
displayed is heavily dependent on the riding style over the
last 20 kilometres.

6.3.5 Enabling push assist
Push assist helps you when pushing the bike.
WARNING
Push assist may only be used when pushing the pedelec. Otherwise
you could seriously injure yourself. Push assist is not designed to
provide assistance when someone is sitting on the pedelec. On back
pedal models, the pedal crank also turns.
Push assist helps you when pushing the bike (up to max.
6 km/h). This is particularly helpful when you want to push
your pedelec uphill.
1. Press and hold the button. The
push assist is activated after three
seconds. A warning is sounded at the
same time on the Impulse Evo (Smart)
display. Note (1/1) Push assist or
Note | Push assist is shown.
Keep the button pressed until you no
longer need push assist.

result of a serious accident.
6.4.3.15 Shift sensor
Path: Settings | Device settings | Drive | Shift sensor
The shift sensor detects gear changes and interrupts the motor assist for
a fraction of a second (ms = milliseconds). This enables smoother and
quicker gear changes especially with a hub gear. This makes the shift
process more gentle for the pedelec. The higher the value selected, the
longer the interruption to the motor assist and the more time the gear has
to change.
1. Navigate to “Shift sensor” as described in 6.4.1 Configuring settings
in the main menu Page EN-54.

6.4.3.16 Climb assist
Path: Settings | Device settings | Drive | Climb assist
The power sensor in the motor registers your pedalling force as you ride.
The motor controller interprets the pedal power signals and responds
(dierentlydependingontheclimbassistvaluesetting).Thelowerthe
set value (e.g. 1), the more sluggish the reaction of the motor when assist
is enabled. With a high value (e.g. 7), the motor reacts very responsively
to the pedal force. When riding uphill it can be an advantage if the power
sensor does not react so sensitively, so as to provide the motor assist as
evenly and smoothly as possible.

6.5 Tips
6.5.1 Transporting your pedelec
WARNING
Remove panniers and other attachments during transport, as they can
comeoandcauseseriousaccidents.
Always remove the battery before transporting the pedelec.
There is a risk of injury due to accidental activation of the button.
The battery could also fall from the docking station and be damaged.
Use a special battery bag that protects the battery from heat, shocks
and impacts.
By car: The bike rack must be designed for the higher weight of the
pedelec VI.I Overall weight Page EN-10, otherwise it can break and
cause a serious accident. It is imperative to follow the guidance of
the bike rack manufacturer.
IMPORTANT
Pedelecs carried on a rear-mounted bike rack must have suitable
weather protection. This applies particularly to the docking station,
which must be protected from water ingress. Water ingress can
damage the motor and its components.
Bus, train and plane: Find out from your travel company
well in advance if their regulations allow you to take your
pedelec with you.
6.5.2 Trailer bikes and trailers
The use of trailer bikes and trailers is generally permitted for the Impulse
Evo / Impulse Evo Next pedelec, but please observe the following safety
instructions:
DANGER
Do not exceed the overall weight of the pedelec because parts
important for safety might fracture or fail. If this happens while
you are riding the bike, it can lead to severe falls – with fatal
consequences VI.I Overall weight Page EN-10.
Trailer bikes and trailers alter the riding characteristics. Adapt your
riding style accordingly. If you do not adapt your riding style, you
could seriously injure or kill yourself or the child in the trailer. The
braking distance becomes longer, so you have to start braking earlier,
and the steering response becomes more sluggish. Practise starting,
braking, going round corners, and up and down hills, starting with an
empty trailer bike or trailer.
Only use trailer bikes and trailers that conform to the relevant
national regulations. In addition, they should be designed and tested
in accordance with DIN EN 15918. Otherwise components could
break while you are riding the bike; resulting in serious or even fatal
injuries for you and/or your child. Please consult your cycle dealer if
you want to purchase a trailer bike or trailer.

6.5.4 Storage
1. Remove the battery from the pedelec.
2. Store the battery in a dry, not excessively warm room. The battery
should not be exposed to direct sunshine. The recommended storage
temperaturerangeis18to23˚C.
6.5.5 Cleaning
WARNING
Remove the battery before cleaning the pedelec. Accidental activation
of the button can result in severe injuries.
IMPORTANT
Do not clean the pedelec and its components with a water hose or high
pressure washer. Althoughthecomponentsaresealedo,damage
may still result. Clean the bike with a soft damp cloth.
Do not immerse the drive unit or components into water. Damage may
still result even though the components are sealed.
Do not use any cleaners which contain alcohol or solvent, or which
scour. No coarse sponges or brushes may be used either. They leave
scratches and cause the surface to become matt. Clean the bike with a
soft damp cloth.

9.3.1.2 Capacity
Capacity indicates the quantity of electric charge that a
batterycandeliverorstore.Itisspeciedinamperehours
(Ah). Even when used properly, capacity diminishes over
time due to chemical reactions (ageing). So it reduces
with every charging cycle for example. A battery also ages
slightly when it is not used.
A charging cycle is the complete charging of a battery from
0 to 100% capacity. It follows that not every charging
process equates to a charging cycle. For example, a charge
from 50 to 100% capacity is only half a charging cycle.
1. Pressthebatterybuttonforveseconds.Themaximumavailable
capacity (state of health) of the battery will be displayed.
Display Description Battery charge level
100%  3 – 5 LEDs light up The battery has a capacity

The battery may need to be replaced when fewer than
3 LEDs light up. Discuss how to proceed with your cycle
dealer.

9.4 Tips
9.4.1 Range
Various factors determine how far you can go with your battery:
When you go on a long trip it is worth taking a spare battery
or battery charger with you.
Rideprole:Youneedthemostpowerinthehighestrideprole
(Dynamic). The range becomes shorter.
Selecttherideproleinlinewiththeroutesyouride.For
a leisurely tour with friends at the weekend, the “Relax”
assist level is the right choice. If you often cycle at greater
speed (such as to work), the “Dynamic” setting can inject
the necessary pace.
Assist mode: You consume the most battery power in the highest assist
mode. The range decreases, the higher the selected assist mode.
Vary the assist modes you use. If there is a tailwind when
going downhill or on the level, you can still go fast with a
lower assist mode.
Tyre pressure: If the tyre pressure is too low it is harder for the tyres to
rotate. The drive unit needs to provide more assistance and the range
decreases.
Seat tube battery: Seat tube battery:

Removing the battery
Original User Guide | Pedelec Impulse Evo / Impulse Evo Next Version 4 EN-89
Charging a smartphone: Connecting a smartphone to your Impulse Evo /
Impulse Evo Next Smart display to charge it also requires power.
9.4.2 Storage
1. Remove the battery from the pedelec.
2. Store the battery in a dry, not excessively warm room. The battery
should not be exposed to direct sunshine. The recommended storage
temperaturerangeis18to23˚C.
IMPORTANT
The battery should not be stored in a fully charged state. A charge
level between 50 and 70% () is ideal. Since the battery loses
charge very slowly, you should recharge it when only one or two LEDs
come on, but after six months at the latest.
Riding style: A low pedalling speed combined with high gears results in
high power consumption.
Change down in good time to maintain constant cadence,
especially when starting.
Yourtnesslevel:Thetteryouare,thelessassistanceyouwillneed.
Total weight: The lower the total weight supported by the bike, the easier
it will be to ride VI.I Overall weight Page EN-10.
Outside temperatures: The lower the outside temperatures (e.g. cold in
winter), the shorter the range.
Insertthebatteryjustbeforestartingowithyourpedelec.
This way you prevent low temperatures shortening the
range.
Battery capacity: A much shorter service life after the charging process
indicates that the battery has lost considerable capacity. 9.3.1.2
Capacity Page EN-85.
The battery may have to be replaced. Discuss how to
proceed with your cycle dealer.
Route selected: You need to pedal harder when cycling uphill or against
strong head wind. This is registered by the power sensor, which in turn
requires the motor to work harder.

9.4.3 Cleaning
DANGER
If you wipe the battery avoid touching the contacts, otherwise there is
the risk of an electric shock.
WARNING
Remove the battery from the pedelec before cleaning. Unintentionally
pressing the button represents a risk of injury.
CAUTION
Batteries must not be immersed in water. This presents a risk of
explosion. Do not extinguish a burning battery with water, only the
surroundingburningmaterial.Fireextinguisherswithmetalre
powder (Class D) are more suitable. If it is possible to take the battery
safelyoutside,smothertherewithsand.Butyouneednotbeafraid
of the battery exploding under you when you ride the cycle through
rain. The battery is sealed to prevent moisture and spray water from
entering.
IMPORTANT
Do not spray the battery with a water hose or wash it with a high-
pressure cleaner. Damage to the battery may still result even though
the components are sealed. Clean the battery with a soft, damp cloth.
Do not use any cleaners which contain alcohol or solvent, or which
scour. No coarse sponges or brushes may be used either. They leave
scratches and cause the surface to become matt. Clean the battery
with a soft, damp cloth.
Do not allow dirt to dry out. It is best to clean the battery
immediately after your ride.
1. Remove the battery from the pedelec.
2. Clean the casing with a slightly damp, soft cloth.
3. If the battery terminals are dirty, clean them with a dry, soft cloth.

10.1 Safety information
DANGER
Battery chargers are not a toy and must not be used by children
undertheageof8years.Olderchildrenmustbesucientlytrained
on how to use the battery charger. People who, because of their
physical, sensory or intellectual capabilities, or because of their lack
of experience or knowledge, are unable to use battery chargers, are
prohibited from using them unless supervised or under the instruction
of a responsible person. Otherwise there is a risk of mishandling with
consequential very serious injuries.
WARNING
Only use the correct, original charger to charge the battery. The use of
otherbatterychargerscancauseexplosions,seriousburnsandres.
Further consequences can include malfunctions and a limited battery
life.Youcanndalistofpermittedchargersin 11.3 Charger Page

b) A learning cycle has not been carried out. Perform a ‘learning cycle’: A new, fully charged battery should be run down once until the
motor assist stops and without recharging in between. In that way the battery ‘learns’ its
capacity, and the actual capacity will agree with the level indicated on the battery status
display. As soon as the battery enters Sleep mode, press the battery button for one second.
Then the learn cycle can be continued. Please perform a learn cycle every six months or
5,000 kilometres. If you do not repeat this from time to time, the actual capacity of the
battery will increasingly diverge from the value on the battery status display.

DANGER
Only use appropriate tools to tighten screws and bolts. Observe
thespeciedtorquesetting.Thecomponentmanufacturer'storque
settings take precedence (where available). Failure to comply can
result in screws/bolts becoming loose, tearing away or fracturing. If
that happens while you are riding the bike, components may come
oandyoucouldhaveaseverecrash.Ifscrewsareovertightened,
components can also be damaged. Tighten all screws and bolts
that are relevant for safety with a torque wrench. This indicates the
corresponding torque in newton metres (Nm).
If no values are shown on the component or component manuals, use the
torque settings from the following table.
