3.3.9.1 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
pedelec riders no longer pedal, the temperature is
outside the permitted range, there is an overload
or the
of 25 km/h has been
reached.
A push assist system can be switch on. The speed
depends on the selected gear. The motor will
continue to drive the pedelec as long as pedelec
riders press the
push assist button
on the control
panel. 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. 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.
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 force is determined by the set level of
assistance.
