3.3.8.1 Motor
As soon as the muscle power required for
pedalling passes a certain level, the motor is
activated gently and assists the pedalling motion.
The motor power always depends on the power
used to pedal: Motor assistance is lower when
little muscle power is used than when muscle
power is used. This happens regardless of the
level of assistance.
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 45 km/h has been
reached.
A push assist system can be activated. The speed
depends on the selected gear. The motor
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 electric drive system stops when the

push assist button is released. The pedelec does
not have a separate emergency shut-off button. In
the event of an emergency, the motor can be
stopped by removing the on-board computer. The
mechanical brakes are used as an emergency
stop system and bring the bicycle to a halt quickly
and safely in the event of an emergency.

Each pedelec is supplied with a charger. The
following BOSCH charger may be used:
• the 4 A Charger BPC3400.
Observe the operating instructions in the

• the front lamp (also known as headlight or front
light)

The headlight and the rear light are also on
whenever the riding light is activated.
