About these operating instructions
1.5 Aim of the operating instructions
These operating instructions are not a substitute
for personal instruction by the specialist dealer
supplying the bike. These operating instructions
are an integral part of the pedelec. Therefore, if it
is re-sold at a later time, they must be handed
over to the subsequent owner.
These operating instructions are mainly written for
people riding pedelecs.
Paragraphs with a white background are intended
to enable non-professionals to make safe settings
on the pedelec, use it, clean it and identify and
eliminate any faults.
Sections intended for technical staff are
highlighted in blue and marked with a spanner
symbol.
These sections aim to allow trained technical
staff (bicycle mechatronics engineers, bicycle
mechanics or others) to carry out initial
assembly, adjustment, inspection and repair
safely.
Technical staff also need to read all sections for
pedelec riders and operators to ensure they can
provide better customer service.
Always fill out all reports in Section 11.1 and
Section 11.2 when carrying out work.

2.1 Residual risk
Pedelecs pose the following residual risks:
•Risk of fire and explosion
•Electric shock
•Risk of a crash
•Risk of amputation
•Key breaking off
•Malfunctions due to Bluetooth®
Never charge if there is a critical fault
If a charger is connected to the drive system when
a critical error is reported, the battery may be
damaged permanently and may catch fire.
Connect charger to fault-free electric drive
system only.
Protect against penetrating water
The battery is only protected from spray water.
Penetration by water can cause a short circuit.
The battery may self-ignite and explode.
Never immerse battery in water.
Take battery out of service if you suspect water
has penetrated it.
Avoid heat
Temperatures over 60 °C can also cause liquid to
leak from the battery and the battery will become
damaged. The battery may self-ignite and
explode.
Protect the battery against heat.
Never store next to hot objects.
Never expose battery to continuous direct
sunlight.
Avoid wide temperature fluctuations.
Never use incorrect charger
Chargers with excessive voltage damage
batteries. This may cause a fire or an explosion.
Only use approved batteries to charge.
Prevent short circuit due to interconnection
Metal objects may interconnect the battery's
electrical terminals. The battery may self-ignite
and explode.
Never insert paper clips, screws, coins, keys
and other small parts into the battery.
Place the battery on clean surfaces only.
Prevent charging socket and contacts against
contamination from dirt, sand and similar.
Handling a damaged or faulty battery
Faulty batteries are hazardous goods. These
include
• Cells or batteries which have been identified as
faulty for safety reasons
• Leaked batteries or which have released gas
• Cells or batteries which have sustained external
or physical damage
• Cells or batteries whose safety has not been
tested yet
The safety electronics may fail if the batteries are
damaged or faulty. The residual voltage can
cause a short circuit. The battery may self-ignite
and explode.
Only use and charge the battery and
accessories if they are in perfect condition.
Never open or repair the battery.
Batteries with external damage must be
removed from service immediately.
If a battery is dropped or struck, remove it from
service and keep it under observation for at
least 24 hours.
Contact specialist dealer.
Storing faulty batteries
Your specialist dealer will dispose of faulty
batteries.
2.1.1 Risk of fire and
explosion

MY23B0a - 52_1.0_31.08.2022 16
Safety
Take faulty batteries to your specialist dealer. Avoid overheating in the charger
The charger heats up when charging the battery.
If the battery is not allowed to cool down
sufficiently, it can cause a fire or burns to the
hands.
Never use charger on a highly flammable
surface.
Never cover the charger during charging.
Never leave battery unattended during
charging.
Cool down overheated brakes and motors
The brakes and the motor may become very hot
during operation. There is a risk of burns or fire in
case of contact.
Never touch the brakes or the motor
immediately after a ride.
Never place the pedelec on a flammable
surface, such as grass or wood, directly after
use.
Store the battery in a safety container in
a dry place as per special regulations
(ADR SV 376, P908) until you dispose of it.
Figure 1: Example of a safety container
Never store near flammable substances.
Dispose of faulty batteries in the correct
manner.

MY23B0a - 52_1.0_31.08.2022 17
Safety
.
Never use damaged network components
Damaged chargers, cables and plug connectors
increase the risk of electric shock.
Check the charger, cable and plug connector
before each use. Never use a damaged
charger.
Avoid water penetrating
If water penetrates into the charger, there is a risk
of electric shock.
Use the charger indoors only.
Dealing with condensate
Condensation may form in the charger and in the
battery when the temperature changes from cold
to hot, causing a short circuit.
Wait until both charger and battery are at room
temperature before connecting them.
Set the quick release correctly
Excessively high clamping force will damage the
quick release and cause it to lose its function.
Insufficient clamping force will result in
unfavourable transmission of force. This can
cause components to break. This will cause a
crash with injuries.
Never fasten a quick release using a tool (e.g.
hammer or pliers).
Only use the clamping lever with the specified
set clamping force.
Use correct torque
If a screw is fastened too tightly, it may break. If a
screw is not fastened enough, it may loosen. This
will cause a crash with injuries.
Always observe the indicated tightening torque
on the screw or in Section 3.5.11.
Use approved brakes only
The wheels are designed exclusively for use with
rim brakes or disc brakes. The wheel may break if
an incorrect brake is used. This will cause a crash
with injuries.
Only use the approved brakes on the wheel.
The brake disc in disc brakes is so sharp that it
can cause serious injuries to fingers if they are
inserted into the brake disc openings.
The chain wheels and belt sprockets can draw in
fingers, thus causing serious injuries to fingers.
Always keep fingers well away from rotating
brake discs and the chain or belt drive.
2.1.5 Key breaking off
If you leave a key inserted when riding or
transporting the pedelec, it may break off or the
locking system may open accidentally.
Pull the key from the battery lock.
2.1.2 Electric shock
2.1.3 Risk of a crash
2.1.4 Risk of amputation

Safety
2.1.6 Malfunctions due to Bluetooth®
If you use the on-board computer with Bluetooth®
and/or Wi-Fi®, it may cause interference with
other devices, other equipment, aircraft, and
medical devices, such as pacemakers and
hearing aids.
Likewise, it cannot be completely ruled out that
you will cause harm to people and animals in the
immediate vicinity.
Never use the pedelec with Bluetooth® when
in close proximity to medical devices, filling
stations, chemical plants, areas at risk of
explosion and in blasting zones.
Never use pedelec with Bluetooth® in aircraft.
Avoid operating for longer periods in close
proximity to the body.

Safety
2.2 Toxic substances
If substances are released or used which pose a
risk to people and the environment, effective
protective measures must be taken.
Possible hazards, contamination and health
hazards due to:
• Carcinogenic, germ-cell-mutagenic and
reproduction-toxic substances
• Toxic substances
• Irritants (skin, respiratory system) and
corrosive substances
What might happen?
• Serious harmful effects to health
• Threat to life
• Hazard to bystanders due to carry-over and
contamination, including in personal sphere.
Toxic substances (also known as poison or toxins)
refer to substances which can cause damage to
living beings if they enter the organism above a
specific low dose. The more the ingested amount
of a toxic substance increases, the greater the
likelihood of damage to health due to poisoning is.
This can lead to death.
Brake fluid
Brake fluid may leak out after an accident or due
to material fatigue. Brake fluid can be fatal if
swallowed or inhaled.
Never dismantle the brake system.
Avoid contact with skin.
Do not inhale vapours.
Corrosive substances (also known as corrosives)
destroy living tissue or attack surfaces. Corrosive
substances may be in solid, liquid or gaseous
form.
Irritants are hazardous substances which irritate
the skin and mucous membranes once you come
into contact with them. This may cause
inflammation of the affected areas.
Defective battery
Liquids and vapours may leak from damaged or
faulty batteries. Excessively high temperatures
may also cause liquids and vapours to leak from
the battery. Such liquids and vapours can irritate
the airways and cause burns.
Never dismantle the battery.
Avoid contact with skin.
Never inhale vapours.
2.3 Requirements for the rider
The rider must have adequate physical, motor and
mental abilities to ride on public roads. A minimum
age of 14 years is recommended.
2.4 Vulnerable groups
Keep batteries and the charger away from
children and people with reduced physical,
sensory or mental capacities or lacking in
experience and knowledge.
