Electric drive system

The pedelec is driven by muscle power applied to
the chain drive. The force which is applied by
pedalling in the direction of travel drives the front
chain wheel. The chain transmits the force onto
the rear chain wheel and then onto the rear wheel.

• A charger which is designed for the battery.
As soon as the required muscle power from the
rider pedalling passes a certain level, the motor is
activated gently and assists the pedalling motion
of the rider. The motor force is determined by the
set level of assistance.
The pedelec does not have a separate emergency
stop or emergency shut-off button. The drive
system can be stopped in case of emergency by
removing the display.
The motor switches off automatically as soon as
the rider no longer pedals, the temperature is
outside the permitted range, there is an overload
or the shut-off speed of 25 km/h has been
reached.
A push assist system can be activated. The speed
depends on the selected gear. The push assist
continues to drive the pedelec as long as the rider
presses the push assist button on the handlebars.
The speed can be a maximum of 6 km/h in this
case. The drive stops when the plus button is
released.

Rechargeable battery

Bosch rechargeable batteries are lithium ion
batteries which are developed and manufactured
to the latest technical standards. These batteries
meet and exceed applicable industrial safety
standards. The battery has an internal electronic
protection circuit, which is specifically designed
for the charger and the pedelec. The battery
temperature is monitored at all times. Each
individual cell in a Bosch rechargeable battery is
protected by a steel cup and cased in a plastic
housing. You must not open this housing. You
must also avoid mechanical loads or exposure to
intense heat since they may damage the battery
cells and cause flammable contents to leak out.
The battery is protected against deep discharge,
overcharging, overheating and short circuit. In the
event of a hazard, a protective circuit switches the
battery off automatically.
The battery has a high energy content when
charged. The substances in lithium-ion battery
cells may become inflammable under certain
