3.3.7.1 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 pre-set level of
assistance determines the motor output.
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 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.

3.3.7.2 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 interior
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.
The battery has a high energy content when
charged. The code of practice for their safe handling
is found in Section 2 Safety and Section 6.9
Rechargeable battery in the operating instructions. If
the electric drive system is not used for 10 minutes
and no button has been pressed on the on-board
computer or the control panel, the electric drive
system and the battery are automatically switched off
to save energy.
The type and duration of operating conditions have a
significant effect on the battery life. Just like any
other lithium-ion battery, the battery will age naturally
if it is not being used. The battery's service life can be
extended if the battery is well maintained and stored
at the correct temperature. The charging capacity will
decrease with age, even if the battery is maintained
properly. If the operating time is severely shortened
after charging, this is a sign that battery has reached
the end of its useful life.
Battery performance is reduced when the
temperature drops since this increases electrical
resistance. As a result, you can expect the range to
be shorter than normal in winter. We recommend
using thermal protection sleeves when riding longer
distances in the cold.
Each battery has its own lock.
