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.

The pedelec also has an integrated electric drive
system in addition to its mechanical 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 electric drive system can be
stopped by removing the
on-board computer in the
event of an emergency. 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
8 components:

6 Electric gear shift (alternative)
7 Motor
• A charger 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. 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 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.
