Introduction

Thank you for choosing the Pedelec Impulse Speed 2.0

om Derby Cycle. This S-Pedelec (= fast Pedelec) is

equipped with an innovative electric drive that assists you

when you are cycling. This will make your trip much more

enjoyable if you are riding up hills, carrying loads or rid-

ing into the wind. You can decide yourself how much you

want to use it.

Although the S-Pedelec looks like a normal bike, it is

classed as an L1e moped, so there are a number of im-

portant dierences: In Germany, you will need a moped

test certicate (if you were born aer 01.04.1965) and an

insurance plate ➠ Chapter 1.2 “Statutory requirements”.

tains or repairs this S-Pedelec.

1 Safety

The User Manual contains the following symbols that de-

note dangers or important information. Read all the safety

information. Failure to observe the instructions can cause

electric shock, re and/or serious injury.

WARNING

regarding possible physical injury, increased

risk of falls or other injuries.

IMPORTANT ADDITIONAL INFORMATION

or special information on using the S-Pe-

delec.

NOTE

regarding possible damage to property or the

environment.

1.1 General

If children are present, keep a close eye on them,

especially if there is a possibility they could insert

objects into the motor through apertures in the

housing. This poses the danger of fatal electric

shock.

If you have reason to suspect a safety problem

with your Pedelec, do not ride it, and make sure

nobody else can use it until you have it checked by

a specialist cycle shop. Safe use is not possible if

electrical components or the battery shows signs

of damage.

Never ride with no hands! This poses an acute risk

of falling.

Take the battery out of the S-Pedelec before begin-

ning work on the S-Pedelec.

Observe the maximum permitted gross weight of

your S-Pedelec, as this could otherwise lead to

breakage or failure of safety-relevant components

➠ Chapter 12 “Technical data”.

It is not permitted to carry children in a bike

trailer pulled by an S-Pedelec. Trailers themselves

are permitted, provided the trailer coupling used

has the national type approval (ABE) required for

motor vehicles.

If you wish to make any adjustments to the ride

characteristics of your S-Pedelec, please consult

your specialist cycle shop.

Original User Manual | Pedelec Impulse Speed 2.0 5

1.2 Statutory requirements

The S-Pedelec is classed om a legal point of view

as an L1e moped. In some EU countries it must,

like all other motorcycles and motor vehicles,

comply with certain regulations, for example the

Road Trac Licensing Regulation in Germany

(StVZO). Please observe the relevant explanations

and general information provided in the “Original

User Manual | General” (CD).

The following statutory requirements apply for an

S-Pedelec:

•When riding with the power assist only, the S-

Pedelec must not travel faster than 20 km/h. You

will therefore reach a speed of between 15 and

18 km/h on the at.

•The power assist switches itself o once you

have reached a speed of roughly 45 km/h. This

requires around 700 watts of power, which can-

not be supplied by the electric motor alone. You

can reach speeds of 35-45 km/h by combining

the motor's output of 350 watts with your own

physical eort.

1.2.1 Requirements for the rider

You are legally required to wear a helmet. You

should wear a suitable helmet (e.g. a bicycle hel-

met).

You are legally required to have a driving license.

The moped test certicate is mandatory. If you

have a German driving licence, you are automati-

cally exempt om this requirement.

In Germany, if you were born before 1 April 1965,

you may also ride an S-Pedelec without a driving

licence.

You are legally required to have insurance. In Ger-

many, you can obtain the small registration mark

om any insurance company.

Use on cycle paths is restricted. When you use

your S-Pedelec as a normal bike, i.e. without as-

sistance om the electric motor, you can ride on

all cycle paths without restriction. When you use

the motor, restrictions apply in some EU countries.

In Germany an amendment to the Road Trac

Ordinance (StVO) states that: Outside built-up

areas, you must ride your S-Pedelec on cycle

paths, as also applies to mopeds. In exceptional

cases where this is not permitted, the cycle path

will be marked with the sign “No mopeds” in ac-

cordance with Paragraph 2 Section 4 of the Road

Trac Ordinance (StVO). Inside built-up areas, on

the other hand, you can only use your Pedelec on

cycle paths if there is a sign to indicate that it is

permitted in accordance with Paragraph 41,

Sec. 2, No. 5.

These regulations apply to you wherever you are

in the European Union. It is possible that dierent

regulations exist in other countries, also inside

the EU in individual cases. Before using your

S-Pedelec abroad, nd out about the applicable

legislation in the relevant country.

1.3 Battery

The battery contains chemical substances, which

could cause dangerous reactions if the safety in-

formation given here is not adhered to.

Avoid contact with liquid leaking om a damaged

battery. In case of contact, rinse o the liquid with

water. In case of eye contact, consult a doctor

aer rinsing.

Never attempt to repair your battery. Batteries

must not be dismantled, opened or crushed. The

improper opening or damaging of the battery

poses the risk of serious injury. Opening the bat-

tery voids the warranty claim. If your battery is

damaged, contact your specialist cycle shop for

advice.

Batteries must not be exposed to heat (e.g. radia-

tor) or naked ames. External heat can cause the

battery to explode. In addition, high temperatures

shorten battery life. When charging, always ensure

there is adequate ventilation.

6 Original User Manual | Pedelec Impulse Speed 2.0

A battery must not be short-circuited. It is dan-

gerous to store batteries a box or drawer where

they can short-circuit one another or can be short-

circuited by other conductive materials (paper

clips, coins, keys, nails, screws). A short circuit

between the battery contacts can cause burns or

re. Short-circuit damage caused in this way voids

all guarantee claims.

Batteries must not be exposed to mechanical

shocks. Even if a battery shows no visible signs

of damage aer falling or being knocked, it may

be damaged. For this reason, even batteries that

seem ne must be taken to a specialist dealer for

inspection. Damaged batteries must neither be

charged nor used for another application.

Keep batteries away om children.

Use the battery solely for your S-Pedelec.

Ideally, take the battery out of your S-Pedelec

when not in use.

Batteries not designed for the Pedelec must not be

used.

Never transport damaged batteries. The safety of

damaged batteries cannot be guaranteed.

Lithium reacts very strongly upon direct contact

with water. Never put the battery into water. Cau-

tion is therefore also required in the case of dam-

aged batteries which have become wet, as they

may catch re.

In case of re, water can be used to extinguish any

ames in the vicinity, but never the battery itself.

Powder re extinguishers for metal res (Class D)

are better suited to this task. If the battery can be

safely moved outdoors, the re can also be suo-

cated using sand.

The S-Pedelec operates at low voltage (36volts).

Never attempt to operate the Pedelec using power

om a source other than a genuine Pedelec bat-

tery. The designations of approved batteries are

listed in ➠ Chapter 12 “Technical data”.

1.4 Charger

The charger may only be used to charge the bat-

tery supplied. Use of the charger for other pur-

poses is not permitted. Any kind of manipulation

of the charger or battery housing is forbidden!

The mains voltage must correspond to the voltage

given on the type plate of the charger. The supply

voltage of the charger is given on the type plate on

the back of the device.

The charger is only intended for use indoors. The

battery may only be charged in a dry, non-amma-

ble environment. During the charging process, the

battery and charger must be placed on a at, non-

ammable surface. Battery and charger must not

be covered. There must be no highly combustible

materials in the immediate vicinity. This also ap-

plies when charging the battery on the S-Pedelec.

In this case, you must place the S-Pedelec so as

to prevent any re om spreading quickly (avoid

carpeted oors!).

Ingress of water and damp in the charger must

be avoided at all costs. In case of ingress of wa-

ter, immediately disconnect the charger om the

mains and have it checked by a specialist.

The battery may heat up during charging. A maxi-

mum temperature of 45°C may be reached. If the

battery becomes any hotter than this, stop the

charging process immediately. Such a battery may

no longer be used, and you must have it inspected

by the dealer.

A battery that displays a fault must not be

charged.

The battery must not be le unattended while

charging.

Damaged batteries must not be charged (risk of

explosion!).

Do not attempt to modi or take apart the charger.

Have repairs carried out only by specialists.

A charger with a damaged mains plug or mains ca-

ble must not be connected to the mains and must

be replaced by a specialist. The same applies for

extension cables that are not in perfect condition.

Original User Manual | Pedelec Impulse Speed 2.0 7

live. Maintenance or repairs on the motor when it

is open must only be carried out by a professional

bike workshop.

1.6 Adjustments/maintenance/repair

When carrying out adjustments and maintenance

or when cleaning, avoid crushing cables or damag-

ing them with sharp edges.

Please have all installation and adjustment work

carried out by your specialist cycle shop. In case

you have to fasten something in place or change

something yourself, you will nd an exhaustive list

at the end of the “Original User Manual | General”

(CD) detailing the tightening torques which must

always be adhered to.

Do not charge batteries for an extended period if

they will not be used.

If you detect smoke or an unusual smell, immedi-

ately unplug charger at the wall socket and discon-

nect the battery om the charger.

No chargers other than those specically intended

for use with the battery may be used. The use of a

dierent charger may cause malnctions, short-

ened service life, re or explosion.

Do not use damaged batteries or chargers (plug,

housing, cable).

Do not replace the mains cable. This poses the risk

of re and explosion.

Condensation may form on the charger if the

temperature changes suddenly om cold to hot.

In case of condensation, wait approximately one

hour before connecting the charger to the mains,

until it has warmed up to the temperature of the

room. Ideally, avoid such situations by storing the

charger in the place where it is operated.

Only charge the battery at ambient temperatures

of between 0°C and 45°C. You can maximise a

battery's service life, however, by charging it at an

ambient temperature of between 10°C and 30°C.

1.5 Motor

If children are present, keep a close eye on them,

especially if there is a possibility they could insert

objects into the motor through apertures in the

housing. This poses the danger of fatal electric

shock.

Bear in mind that the motor can heat up on long

ascents. Be carel not to touch it with your hands,

feet or legs. You could burn yourself.

Live parts may be exposed when you open covers

or remove parts. Connection points may also be

1.7 Transportation of the S-Pedelec

For the transportation of your S-Pedelec, we rec-

ommend removing the battery om the S-Pedelec

and packaging it separately. A suitable transport

container can be obtained om your specialist

cycle shop.

1.7.1 The S-Pedelec and your car

If you transport your S-Pedelec on a bike rack, ensure that

it is designed for the higher weight of a Pedelec. To reduce

the load on the rack, and for protection against the weath-

er, the battery must be transported inside the car.

1.7.2 The S-Pedelec on trains

In Germany, you can take your S-Pedelec with you on

trains which are marked with the bike symbol. On German

Intercity (IC) and EuroCity (EC) trains, you must book a

place for your bike in advance. Bikes are not permitted on

German Intercity Express (ICE) trains.

1.7.3 The S-Pedelec on aeroplanes

Your Pedelec is generally subject to the policies of the

respective airline concerning bikes. Batteries are subject

to dangerous goods legislation. Therefore, they must not

be carried on passenger planes – neither in the cargo

hold, nor the cabin. Please contact the relevant airline for

detailed information.

3 First steps

3.1 Checking the tightening torques

Check that all screws and important components are fas-

tened securely and correctly. You will nd a table with the

prescribed tightening torques for important screw con-

nections in ➠ Chapter 30 “Technical data” of the “Original

User Manual | General" (CD).

3.2 Fitting the pedals

It may be that the pedals for your S-Pedelec have yet to be

tted:

The right pedal (marked with an “R”) is screwed clockwise

into the right crank arm. The le pedal (marked with an

“L”) is screwed anticlockwise into the le crank arm. Both

pedals are screwed in tightly in the direction of the ont

wheel using a size15 open-ended spanner or a suitable

Allen key. The tightening torque is 40Nm.

If the pedals are not screwed in straight, the

thread in the crank arm may be severely damaged.

This could lead to serious accidents and injuries.

3.3 Adjusting the saddle height

3.3.1 Clamping bolt

If a torque is specied (in Nm) on the seatpost clamp,

tighten the clamping bolt to this torque. If no tightening

torque is specied, tighten an M6 bolt (dia. 6mm) and an

M5 bolt (dia. 5mm) to 5.5Nm.

3.3.2 Quick-release device

For opening, the quick-release lever must be folded back

through 180° – you will see the lettering “OPEN”. For clos-

ing, fold the quick-release lever back in through 180° –

you will see the lettering “CLOSE”.

Opening the quick-release lever

OPEN

Closing the quick-release lever

As a rule of thumb, you can be condent that the

quick-release device is suciently secure if the

lever can only be closed by applying rm pressure

with the heel of your hand. You will feel increasing

resistance om the lever, beginning when it is at

approx. 90°. If the seatpost is not clamped rmly

or securely enough, tighten the clamping nut or

turn the screw clockwise by another half a turn

respectively while the quick-release lever is open.

Close the quick-release lever and check that the

saddle is securely fastened once more.

Check that all quick-release levers are fastened

correctly and securely before every journey and

every time you return to your bike having le it

unattended, even for a short time.

With regard to the saddle height, there is a simple

test procedure: Whilst sitting on the saddle, the

heel of your lly-stretched leg should just reach

the pedal in its lowest position. When the ball of

your foot is in the same position, your leg should

be bent slightly.

ashing and stays lit. Now the next LED will begin to

ash. Aer all ve LEDs have gone out, the battery is

lly charged.

If your charger has an LED, and it ashes red con-

tinuously, this indicates a charging fault. Have the

charger and battery checked by your specialist

cycle shop.

4. Unplug the charger at the wall socket once charging is

complete.

Damaged batteries must not be charged, and r-

ther use is not permitted.

The battery may heat up during charging. A maxi-

mum temperature of 45°C may be reached. If the

battery becomes any hotter than this, stop the

charging process immediately.

There is no memory eect, so you can top up your

battery aer every trip. Then you are always ready

for the o.

Ideally you should charge the battery at a temper-

ature of between +10°C and +30°C. It takes longer

to charge the battery at low temperatures, while

the battery will not charge up at temperatures

higher than +45°C. Ideally, you should charge and

store the battery inside your house or in a warm

garage when the outside temperature is low. In

this case, you should only t the battery onto your

bike just before using it.

5.1.3 Installing the battery

1. a) Down tube battery: Insert the battery into the bat-

tery holder of the Pedelec om the ont/above. At the

same time, the key must be in the lock and must be

turned anticlockwise.

b) Seat tube battery: Insert the battery into the holder

of the Pedelec om the le by tilting it outwards at

roughly 45°.

The range of the battery is less in winter due to

the lower temperatures. Only move the battery

(om the warm room where you store it) and t it

on your Pedelec just before you set o. This will

help to prevent the eect of the low temperature

on the range of the battery. ➠ Chapter 5.4 “War-

ranty and service life”.

5.3 Battery management

The battery management monitors the temperature of

your battery and warns you of incorrect use.

If an external short-circuit has been caused at the

contacts or the charging socket, please consult

your specialist cycle shop.

Never leave the battery unattended during charg-

ing. Disconnect the charger aer use.

5.3.1 Sleep mode

The battery management switches the battery to sleep

mode to prevent a so-called deep discharge. At the latest,

the battery management activates the sleep mode aer

ten days without use. The system exits sleep mode when

you connect the battery to the charger or press the battery

button or push button on the battery. This “wakes up” the

battery.

16 Original User Manual | Pedelec Impulse Speed 2.0

Down tube battery: If the battery does not wake

up, the cell voltage may be too low. In this case,

connect up the charger and press the battery but-

ton. The battery is charged for one minute.

Seat tube battery: The battery can also be put into

sleep mode manually by pressing the push button

for eight seconds. Release the push button as soon

as the second LED lights up.

5.4 Warranty and service life

Batteries are wear parts. Wear parts come with a two-year

warranty.

If a fault occurs during this period, your specialist cycle

shop will replace the battery. Normal ageing and battery

wear do not constitute a fault.

The service life of the battery depends on dierent factors.

The most important wear-relevant factors are:

•The number of charges

Aer 1,100 charging cycles, your battery will still

have 60% of its initial capacity, providing it has

been well looked aer. This means 6.6 Ah in an 11

Ah battery and 7.2 Ah in a 15.5 Ah battery. A charg-

ing cycle is dened as the sum of the individual

charges until the battery has been charged to ll

capacity once.

For example: You charge the battery with 5 Ah on

the rst day, 2 Ah on the second day and 4 Ah on

the third day; the sum is 11 Ah. The battery has

thereby completed one charge cycle.

According to the technical denition, the battery is

exhausted when less than 60% of the initial capac-

ity is available. If you can still ride the distances

you require with the remaining battery capacity,

you can of course continue using it. If the capacity

is no longer sucient, you can take your battery to

a specialist cycle shop, which will dispose of your

battery and sell you a new one.

• The age of the battery

A battery also ages during storage.

This means that even if you do not use your bat-

tery, its capacity reduces. You can expect the bat-

tery to age by approximately 3 to 5%.

Ensure that the battery does not become too hot.

The rate at which the battery ages increases signi-

cantly at temperatures above 40°C. Direct sunlight

can heat the battery considerably. Be sure not to

leave the battery in a hot car, and always stand

your Pedelec in the shade during breaks in cycle

trips. If you cannot prevent exposure to heat, do

not charge the battery until it has cooled down.

A lly charged battery ages at an even greater rate

than a partially charged one at high temperatures.

•If you always ride with maximum motor output,

your motor will always require a higher current.

Higher currents cause the battery to age more

quickly.

•You can also extend the service life of the bat-

tery by using the assistance selectively. Use a

low assist level when riding. With lower dis-

charge currents, you conserve your battery.

Make sure that the battery is lly charged before

you ride your bike for the rst time or if you have

not used it for a while.

5.5 Storage

If you do not need your battery for a while, store it at a

temperature of 18 – 23°C at 50–70% of its ll charge ca-

pacity. If you do not use the battery for six months, you

must recharge it.

5.6 Ordering a replacement key

We recommend you note down the key number on the

receipt. If you lose the key, you can order a replacement

key using this number.

If you no longer have the key number, the only option is

to remove the bicycle lock. Contact your specialist cycle

shop in this case.

Original User Manual | Pedelec Impulse Speed 2.0 17

5.7 Shipping

Never send your battery by post or courier! A bat-

tery is a hazardous article which can overheat and

catch re in certain conditions.

The preparation and shipping of a battery may only be

carried out by trained personnel.

If you would like to return your battery for repair or re-

placement, please always arrange this via your specialist

cycle shop. Specialist cycle shops can have the battery

picked up ee of charge and in compliance with danger-

ous goods legislation.

5.8 Disposal

Batteries must not be disposed of with domestic waste.

Consumers are legally bound to dispose of used or dam-

aged batteries at the locations designated for the purpose

(battery collection point or specialist cycle shop). The

disposal of batteries is clearly regulated in each country's

laws.

6 Charger

If used incorrectly, the charger may be damaged or

cause injury.

•Only use the charger in dry rooms.

•Only place the charger in a secure, stable posi-

tion on a suitable surface.

•Do not cover the charger or place any objects on

it, as otherwise it could overheat and catch re.

Do not use any other charger. Only charge your

battery using the charger provided, or a charger

approved by us.

Read the type plates on the charger before using it

for the rst time.

You can charge your Pedelec Impulse Speed 2.0 directly

via a charging socket in the battery. The battery can re-

main on the S-Pedelec whilst charging is in progress.

Charging the battery

SEAT TUBE BATTERY

Alternatively, you can take the battery out of its holder

and charge it elsewhere. This is recommended if it is cold

outside, in order to charge the battery in a warmer room.

The battery can be charged at temperatures between 0°C

and 45°C.

8 The motor

8.1 Operation

If you switch on the assistance and start pedalling, the

motor starts as soon as the rear wheel is turning.

The level of thrust delivered by the motor depends on

three factors:

•Your own pedalling eort.

The motor adapts to the force you apply. If you

pedal harder, e.g. uphill or when setting o, the

power sensor detects this and delivers more power

than if you were only pedalling gently. The assis-

tance increases proportionally if you pedal harder.

The higher the assist level you set, the more pro-

nounced this assistance characteristic becomes.

•The level of assistance you have selected.

In the highest assist level (POWER + SPORT), the

motor delivers the highest output and therefore

also uses the most energy. With the SPORT as-

sist level, the motor produces slightly less power.

If you have selected ECO, you receive the least

amount of assistance but have the battery’s maxi-

mum range at your disposal.

•How fast you ride.

When you set o on your Pedelec, the assistance

increases as you build up speed until it reaches its

maximum, just before the highest assisted speed

is achieved. Then it reduces automatically and

switches o at roughly 45km/h, irrespective of

the gear you are in. Depending on the power-assist

mode you are riding in, the transition between rid-

ing with and without power assist may seem more

or less abrupt.

8.2 Range

The distance you can travel using the power assist with

the battery lly charged depends on several factors:

•Selected assist level

If you want to cover a large distance with power

assist, select the smaller gears, i.e. the ones that

are easier to pedal. Also select a low assist level

(ECO).

•How you ride

If you are riding in gears that are harder to pedal

and select a high assist level, the motor will pro-

duce plenty of power to help you along. However,

just as with driving a car at high speed, this leads

to higher consumption. You will therefore have to

recharge the battery sooner. You can conserve bat-

tery power by pedalling with even force throughout

the complete revolution of the pedals.

•Ambient temperature

If it is colder, you will travel a shorter distance

with the same battery charge. To maximise the dis-

tance you can travel, keep the battery in a heated

room so that it is at room temperature when you t

it on your S-Pedelec.

When the motor is in use, the battery generates

enough heat to not lose too much of its power at

low ambient temperatures. The battery cells can

operate at temperatures of -15°C to +60°C.

•Technical condition of your fast PedelecMake sure

the tyre pressure is correct. If you ride your bike

with too little air in the tyres, this can signi-

cantly increase the rolling resistance, especially

on smooth surfaces, e.g. tarmac. If the ground is

uneven, as on a country path or gravel track, a

somewhat reduced tyre pressure can lead to less

rolling resistance. At the same time, the risk of a

puncture increases. Please consult your specialist

cycle shop about this. The range of your S-Pedelec

also decreases if the brakes are rubbing.

•Battery capacity

The current battery capacity ➠ Chapter 5.2.2

“Checking the capacity”.

•Topography

You pedal harder when riding uphill. This is de-

tected by the power sensor which then allows the

motor to work harder.

9 Troubleshooting

10 Cleaning

Remove the battery before you clean your Pedelec.

Never use white spirits, thinners, acetone or

similar agents for cleaning. Non-neutral cleaning

agents can strip the paint and cause discoloura-

tion, deformation, scratches or defects. Also avoid

using abrasive or harsh cleaners.

Only use household cleaners and disinfectants

(isopropyl alcohol) or water. You can obtain suit-

able cleaning products and additional information

om your specialist cycle shop. We recommend

you clean your S-Pedelec with a damp cloth, a

sponge or a brush.

10.1 Battery

Make sure that water does not enter the battery when

cleaning. Although the electrical components are sealed,

it is not advisable to clean your bike with a hose or high-

pressure cleaner, as it could cause damage. When wiping

down the battery, be carel not to touch and connect the

contacts on the underside. This could cause the battery to

switch o. If the battery connections are dirty, clean them

with a clean, dry cloth.

10.2 Motor

The motor of your S-Pedelec should be cleaned regularly

to remove external dirt, ideally using a dry brush or a

damp (not wet) cloth. Do not use running water such as a

hose pipe or even a high-pressure cleaner.

The ingress of water can damage the motor, so ensure that

no uids or moisture enter the motor at any time during

cleaning.

Do not clean the motor when it is warm, e.g. immediately

aer a trip. Wait until it has cooled down. Otherwise, the

motor may be damaged.

If you remove the motor, e.g. for cleaning purposes, never

hold or carry it by the cables, as there is a risk that they

will break.

You can monitor and inuence the cost of your journeys

with the Pedelec yourself.

The Pedelec Impulse 2.0 Ooad with down tube

battery does not have this nction.

You can reduce your consumption and therefore costs by

following the tips for increasing the range.

The operating costs for power assist with an 11 Ah battery

are calculated as follows:

•A new battery costs roughly 599euros.

•You can cover approximately 80km with one bat-

tery charge.

•You can charge the battery roughly 1,100 times.

•1,100 charging cycles x 80km = 88,000km.

•599euros: 88,000km = 68cents / km

•You use roughly 0.565kWh to lly charge the bat-

tery. Assuming a unit price of 20cents / kWh, it

costs you 11.3cents to lly charge the battery.

•It costs you 14 cents to cover the average range of

80km.

•This means the cost of consumption and the bat-

tery is a maximum of 82cents / km.

This sample calculation is based on German energy prices.

The operating costs may therefore be dierent in locations

where other energy prices apply.

8.4 Warranty and service life

The Impulse centre motor is a durable maintenance-ee

drive. It is a wear part with a two-year warranty. The elec-

tric drive puts an additional strain on parts such as chain,

sprockets and brakes, causing increased wear, compared

to a normal bike.

11 Replacing components of the fast

Pedelec

As your S-Pedelec is a Category L1e moped, it is neces-

sary to obtain a permit om the Federal Motor Transport

Authority and the technical inspection authority (TÜV),

as is the case with other motor vehicles in Germany. This

S-Pedelec has such a permit.

During the approval process, specic components were

dened as being suitable for use with this vehicle. This

means that the permit for your S-Pedelec only remains

valid if exactly the same approved components are used.

If components are modied or replaced, the same require-

ments apply as for other motor vehicles. You must only

use replacement parts that are certied as approved for

your S-Pedelec. Alternatively, you can have components

approved individually by the technical inspection author-

ity (TÜV).

•Pedals: Providing type-approved pedal reectors

are used.

•Mudguard: The ont edge of the ont mudguard

must be rounded.

•Pannier rack

•Saddle

•Handlebar grips

If you remove the motor om the ame of your Pedelec,

check the plug om the motor and battery cable socket for

dirt. If necessary, clean carelly with a dry cloth before

reconnecting.

10.3 Display

The housing of the display must only be cleaned with a

damp (not wet) cloth.

10.4 Control unit

The control unit can be cleaned with a damp cloth if nec-

essary.
