Information
Pedelec/S-Pedelec: Your Pedelec/S-Pedelec does not
have an emergency stop button. You must activate
the brakes to stop the cycle quickly in a dangerous
situation. The maximum brake force is greater than
the propulsion force possible. This means stopping is
guaranteed at all times by pressing the brakes. Note
that the drive system does not disable automatically
after braking. Once you have finished your ride, switch
the drive system to standstill.
You can use the bicycle brakes to slow down and/or bring
your bicycle to a stop. In Germany, bicycles must have two
independent brakes: front and rear wheel brakes. These can
be actuated either by pedalling backwards (coaster brakes)
or by hand (handbrakes). If there are two brake levers on
the bicycle, the left-hand brake lever is usually for the front
brake, and the right-hand brake lever for the rear brake.
This is exactly the reverse in Australia and Great Britain,
where the brake lever for the front brake is on the right,
and that for the rear brake on the left. There are basically
three types of braking systems: hub brakes, rim brakes and
disc brakes. Each braking system can in turn be broken
down into different types. Rim and disc brakes can work
either mechanically – the braking force is transmitted via
a Bowden cable – or hydraulically – the braking force is
transmitted via a liquid. Hydraulic brakes usually work
using pistons which actuate the brake discs symmetrically
from both sides.

23.1 Coaster brakes
Warning
Serious falls and accidents caused by reduced braking
power.
▪ Avoid using the coaster brake continuously on long
downhill stretches, as the internal brake parts can
become very hot, leading to a reduction in braking
power. On long, steep descents, mainly use the
front brake and the manually activated rear brake
if available, to allow the coaster brake to cool. An
extremely overheated coaster brake (discolouration
and grease leaks) must be checked in a specialist
workshop.
Caution
Burns from touching the brake drum.
▪ As the brake drum can become very hot during
extended braking, you should wait for at least
30 minutes after your ride before touching it.
Coaster brakes are a kind of hub brake. If your bicycle is
fitted with a coaster brake, you will need to step backwards
on the pedals to brake. Coaster brakes are activated to a
varying degree depending on the position of your feet and/
or the pedal arms. If the crank arms are vertical, i.e. one of
your feet is directly above the other on the pedals, you will
not be able to brake hard. Position the crank arms horizon-
tally if you want or have to be ready to brake. The braking
power is transferred from your foot over the chain to the
braking system. If you feel that the power of the coaster
brake is decreasing, please contact your dealer.

23.2 Rim brakes
Rim brakes are positioned on the fork and/or the rear frame.
When braking, the brake lining is pressed directly onto the
side of the wheel rim. The brake pads are usually made of
a rubber compound. There are mechanical side-pull brakes,
centre-pull brakes and hydraulic rim brakes, inter alia.
Front mechanical rim brakes can be fitted with a braking
power modulator. This prevents the front wheel from
locking if braking too hard.
