Safety
2 Safety
2.1 Residual risks
2.1.1 Risk of fire and explosion
2.1.1.1 Rechargeable battery
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 observe it for at least 24 hours.
Faulty batteries are hazardous goods. Dispose
of faulty batteries in the correct manner. Store
battery in a dry place until disposal. Never
store in the vicinity of flammable substances.
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 the battery in water.
Put battery out of service if you suspect water
has penetrated it.
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 the battery to sustained direct
sunlight.
Avoid wide temperature fluctuations.
Chargers with excessive voltage damage
batteries. This may result in fire or an explosion.
Only use batteries approved for the S pedelec.
Clearly label the supplied charger.
2.1.1.2 Overheated charger
The charger heats up when charging the battery.
In case of insufficient cooling, this can result in fire
or burns to the hands.
Never use charger on a highly flammable
surface.
Never cover the charger during charging.
Never leave the battery unattended during
charging.
2.1.1.3 Hot components
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 directly
after a ride.
Never place the S pedelec on a flammable
surface, such as grass or wood, directly after
use.
2.1.2 Electric shock
2.1.2.1 Damage
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.
2.1.2.2 Water penetration
If water penetrates into the charger, there is a risk
of electric shock.
Never charge the battery outdoors.
2.1.2.3 Bridging
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.

MY20K10-02_1.0_10.11.2020 8
Safety
2.1.3 Risk of a crash
2.1.3.1 Incorrect quick release setting
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.
2.1.3.2 Incorrect tightening 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 tightening torque indicated
on the screw and in the operating instructions.
2.1.4 Risk of amputation
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.
Always keep fingers well away from the
rotating brake discs.
2.1.5 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, harm to people and animals in the
immediate vicinity cannot be completely excluded.
Never use the on-board computer with
Bluetooth® when in close proximity to medical
devices, filling stations, chemical plants, areas
at risk of explosion and in blasting zones.
Never use the on-board computer with
Bluetooth® in aircraft.
Avoid operating for longer periods in close
proximity to the body.
2.1.6 Key breaking off
If you leave a key inserted when riding or
transporting the S pedelec, it may break off or the
locking system may open accidentally.
Remove the key to the battery lock.

MY20K10-02_1.0_10.11.2020 9
Safety
2.2 Toxic substances
2.2.1 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.
2.2.2 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.
Do not inhale vapours.
2.3 Requirements for the rider
The rider must demonstrate 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 charger away from children
and people with reduced physical, sensory or
mental capabilities or lacking in experience and
knowledge.
If minors use the S pedelec, a legal guardian must
should provide them with comprehensive
instructions.
2.5 Personal protective equipment
Wear a suitable cycling helmet, sturdy footwear
and typical close-fitting clothing to provide
protection.

Safety
2.7 What to do in an emergency
2.7.1 Dangerous situation in road traffic
In the event of any hazards or dangers in road
traffic, apply the brakes on the S pedelec until

emergency stop system in such cases.
2.7.2 Leaked brake fluid
Remove those affected from the danger area to
fresh air.
Never leave those affected unattended.
Immediately remove any clothing items
contaminated with brake fluid.
Never inhale vapours. Ensure sufficient
ventilation.
Wear gloves and safety gloves as protective
equipment.
Keep unprotected persons away.
Take care with leaked brake fluid as it poses a
slip hazard.
Keep leaked brake fluid away from naked
flames, hot surfaces and sources of ignition.
Avoid contact with skin and eyes.

system, water courses or groundwater.
Notify the relevant authorities if fluid
penetrates the ground, water courses or the
sewage system.
Consult a doctor immediately in the event of
any pain or discomfort caused by combustion
gas or leaking fluids.
2.7.3 Battery vapours emitted
