Overview
3.1.4 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.

5 Pedal
The pedelec also has an integrated electric drive
system.
As soon as the required muscle power from the
rider pedalling passes a certain level, the motor is
activated gently and assists the rider’s pedalling
motion. The pre-set level of assistance
determines the motor output.
The pedelec does not have a separate emergency
shut-off button. 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.
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.
The electric drive system is made up of
7 components:

4 Rear light
5 Electric gear shift (alternative)
6 Motor
7 A charger which is designed for the battery.
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 electric drive system stops when the
push assist button is released.
3.1.5 Rechargeable battery
Bosch batteries are lithium ion batteries which are
developed and manufactured to the latest
technical standards. Each individual cell is
protected by a steel cup and encased in a plastic
battery housing. 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. 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.
