This symbol indicates helpful tips, useful or important
information about the product or its additional uses. It does

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
be severely injured or killed. If you do have to tighten something, you
willndacompletelistoftherequiredtorquesettingsinSection
10. Torque settings P. EN-86, which must be strictly followed.
Only use original replacement parts. Replacement parts from other
manufacturers can impair the function of your pedelec. It can result in
serious accidents.

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
willndacompletelistoftherequiredtorquesettingsinSection
10. Torque settings P. EN-86, which must be strictly followed.
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.
