I.II The Impulse 2.0 pedelec
Your Impulse 2.0 pedelec is an electrically power assisted cycle (EPAC).
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 5.4 Changing
assist mode P. EN-34. The drive assistance is dependent on the force and
speed of your pedalling and the speed you are travelling. The motor
assistance stops as soon as you stop pedalling and when the battery is
discharged or if you reach a speed of 25 km/h. If you want to travel faster
than 25 km/h it is therefore necessary to pedal harder.

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. It can result in
serious accidents and falls.
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 the
helmet is correctly positioned.
Keep your hands and other body parts and clothing away from moving
parts,otherwiseyoucouldcatchyourselfinthem,falloand/or
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 are unsure about
a situation.
Only use the bicycle for its intended purpose VI. Intended purpose
P. EN-10, otherwise it can lead to component failure. If that happens
while you are riding the bike you could be severely injured or killed.
DANGER
Inspect your pedelec before every trip, and after each time it has
been transported anywhere or has been left unattended 4. Before
every trip P. EN-30. If wear and damage are not detected in good time,
components may fail. If that happens while you are riding the bike
you could be severely injured or killed. Due to the additional power,
wearing parts on a pedelec are subject to more stress than a normal
bike. Have worn, damaged or bent components replaced before you
use the bike again.
Do not exceed the total weight of the pedelec, because it can lead to
the fracture or failure of safety-relevant parts VII.I Total weight
P. EN-11. If this happens while you are riding the bike, it can lead to
severe falls – with fatal consequences.
Contact your cycle dealer when it is necessary to replace wearing
parts and other II.III Service book P. EN-6 components. We recom-
mend that all assembly and adjustment work is carried out by your
DCW/RU dealer, as incorrect assembly could cause components to
become loose. If that happens while you are riding the bike you could

IMPORTANT
Always park your pedelec so that it cannot tip over. If the bike tips
over components can be damaged. If your bike is not equipped with a
kickstand,onecanberetrotted.PleaseaskyourDCW/RUdealer.
Do not clean the pedelec with a water hose or high pressure washer.
Although the components are sealed, you could damage the bike.
Clean the pedelec with a soft damp cloth.
DANGER
Ask your DCW/RU dealer to show you the operation and features of the
components. Please also read the component guides. We recommend
that all assembly and adjustment work is carried out by your DCW/
RU dealer, as incorrect assembly could cause components to become
loose. If that happens while you are riding the bike you could be
severely injured or killed. If you do have to tighten something, you

WARNING
Do not ride in unfavourable lighting conditions (fog, rain, dusk,
darkness) without adequate lighting V.II.I Lighting P. EN-9; it can
lead to accidents and serious injuries.
Always remove the battery before starting to work on the pedelec.
The pedelec could switch on unexpectedly and you could be seriously
injured.
CAUTION
Do not attempt to open the motor, display, battery or charger;
you could injure yourself. Furthermore, parts may be destroyed,
invalidating the warranty. If problems arise please contact your DCW/
RU dealer.

2. Protection from theft, manipulation and loss
DANGER
Protect your pedelec from unauthorised access. If third parties alter
components (e.g. the brakes) without your knowledge, you could
be seriously injured. Inspect your pedelec before every trip, and
after each time it has been transported anywhere or has been left
unattended 4. Before every trip P. EN-30. If your bike is damaged, do
notrideitagainbeforethedamagehasbeenrectied.Ifyourbikeis
lost or stolen it will not be replaced under the warranty.
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 are only leaving
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. The
pedelec must also be secured with a lock when it is parked
outside the home (e.g. sheds, basement).
Do not park your pedelec in deserted locations – especially
for long periods. If possible, park your pedelec in manned
private or communal garages or individual bike lockers.
Attachthe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. That way the wheel cannot be
stolen. Alternatively, the quick-release levers can be
replaced by an anti-theft device. For questions about this
please contact your DCW/RU dealer.
Use a high quality bike lock: you should invest
approximately 10% of the purchase price of the bike in
locks.YourDCW/RUdealerwillbeabletotasuitable
frame lock if your bike does not already have one.
Alternatively, you can also use other types of bike locks. Ask
your DCW/RU dealer for advice.
Make a note of the important details of your pedelec (e.g.
in the service book II.III Service book P. EN-6, bike
passport) and get it registered with the police. This makes it
easier to identify if it is stolen.
Have the police encode your pedelec; the address and
initials of the owner are engraved on the frame in an
encrypted form. Encoding makes the illegal resale of the
bikemoredicultanddetersthieves.Anencoded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.

3.9 Gears
The gears are operated by controls on the handlebars (gear lever, twist
grips, ...). The gear shift allows you to adjust the gear of your bicycle and
the transmission to the current situation. 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hillwithlittle
eort.Selectthegearssothatyourlegsarealwaysmovingatasteady
pace.
Derailleur*
With this system the chain is lifted on to
a sprocket when changing gear. 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 you must
therefore keep pedalling forwards, never
backwards! – but at the same time ped-
alling lightly and without force.
Hub gear*
Here the change of gear takes place in-
side the rear wheel hub. Space is very
tight inside the hub, therefore it is sen-
sible to pedal lightly when changing
gear.

On some suspension forks it is possible to
alter the air pressure. To do that you will
need the assistance of your DCW/RU dealer–
orifyoufeelcondentofdoingityourself
– a suspension fork pump with a pressure
gauge and the suspension fork manufactur-
er's installation 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
Have damaged components (tears, cracks etc.) replaced before you
use the bike again. If not, important components may fail, causing you
tofallo.
Do not ride the pedelec if it is not in a technically satisfactory
condition. If you are not sure, have it checked out by your DCW/RU
dealer.
Inspect your pedelec before every trip, and after each time it has been
transported anywhere or has been left unattended. Use the following
checklist to help you.
3.11.1 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 exam-
ple, if you are riding up a hill or if you
are standing up from the saddle when
accelerating. To switch the suspension
toxed,turntherotarycontrolonthe
right hand side of the fork to 'LOCK' (or
alternatively: $). To reactivate the sus-
pension, turn the control to the 'OPEN'
position.

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 definitely charge it before
the first long trip 8.3.1 Charging the battery P. EN-75,
because for technical reasons, the battery is supplied only
partially charged (approximately 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. 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. Important: As soon as the
battery switches to sleep mode the learning cycle is interrupted.

6.8.2.10 Climb assist
Path: Device settings I Drive I Climb assist
The power sensor in the motor registers your pedalling force as you ride.
The motor controller interprets the pedalling force signals and responds
according to the climb assist 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.

6.9 Tips
6.9.1 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.
Furthermore, the battery can fall out of the docking station and
become 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 VII.I Total weight P. EN-11, 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, which
must be protected from water ingress. Water ingress can damage the
motoranditscomponents.Youcanndsuitableprotectionatyour
DCW/RU dealer or in the online shop.
Bus, train and plane: Find out from your travel company
well in advance if their regulations allow you to take your
pedelec with you.
6.9.2 Trailer bikes and trailers
The use of trailer bikes and trailers is generally permitted for the Impulse
2.0 pedelec, but please observe the following safety instructions:
DANGER
Do not exceed the total weight of the pedelec, because it can lead
to the fracture or failure of safety-relevant parts. If this happens
while you are riding the bike, it can lead to severe falls – with fatal
consequences VII.I Total weight P. EN-11.
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 is 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. Cycle trailers should also be designed and have been
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 the child. If you are interested in purchasing a
trailer bike or trailer please consult your DCW/RU dealer.

IMPORTANT
Only use the battery to operate this pedelec, otherwise there is a risk
of damage to the device.
Batteries are subject to the dangerous goods regulations.
Private users are permitted to transport them on the road
without further conditions. If transported by commercial
third parties (e.g by air freight, hauliers or logistics
companies) special conditions apply to packing and
labelling. For questions about transporting batteries, please
contact your DCW/RU dealer.
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. Class D extinguishers (for use on metal
res)arebettersuitedforthis.Ifitispossibletotakethebattery

that the battery beneath you could explode while you are riding in the
rain – it is protected from ingress of moisture and condensation.
IMPORTANT
Batteries must not be subjected to mechanical impact. This poses a
risk of damage. A battery can still be damaged after a drop or impact
even if there are no visible signs of damage. Even apparently perfect
batteries should be inspected. Please ask your DCW/RU dealer.
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. Please perform a learn cycle every six months or 5,000
kilometres. When the battery becomes older and you do not repeat
thecyclefromtimetotime,thedierencebetweenactualbattery
capacity and charge level display will become greater and greater.
Important: As soon as the battery switches to sleep mode the learning
cycle is interrupted.

7.3.1.2 Capacity
Capacity indicates the quantity of electric charge that a
battery can deliver or store. It is given in ampere hours
(Ah). Even when used properly, capacity diminishes over
time due to chemical reactions (ageing). So it reduces with
every charging cycle. 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.

7.5 Tips
7.5.1 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.
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 down hill 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.
Riding style: A low cadence (pedalling rate) combined with high gears
consumes the most battery power.
EN-70 Original User Guide | Impulse 2.0 Pedelec Version 3
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 VII.I Total weight P. EN-11.
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signicantlyreducedoperatingtimeaftercharging
indicates that the battery has lost a considerable amount of capacity
7.3.1.2 Capacity P. EN-66.
The battery may have to be replaced. To discuss the next
steps speak to your DCW/RU 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.
7.5.2 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 0 to 20 °C.
IMPORTANT
The battery should not be stored in a fully charged state. A charge
level of 50–70% (

) is ideal. Since the battery loses charge very
slowly, you should only recharge it when only one or two LEDs come
on, but after six months at the latest.
7.5.3 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.

IMPORTANT
Do not spray the battery with a water hose or wash it with a high-
pressure cleaner. Althoughthecomponentsaresealedo,damageto
the battery may still result. 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.

The range appears too short a) The range depends on:

» Assist mode
» Tyre pressure
» Riding style
» Physical condition

» Smartphone charging via display
a) The are many reasons why the range may seem low 7.5.1 Range Page EN-69.
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. 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. Important: As soon as the battery switches to
sleep mode the learning cycle is interrupted.
