Valve

The wheel comprises the wheel itself, an inner
tube with a valve and a tyre.
3.1.1.1 Valve
Each wheel has a valve. It is used to fill the tyre
with air. There is a valve cap on each valve. The
screw-on valve cap keeps out dust and dirt.
The pedelec has either
• a classic Dunlop valve,
• a French valve (also known as a Sclaverand or
Presta valve) or
• a Schrader valve.

Suspension

3.1.2.1 Suspension fork

Unlike a rigid fork, a suspension fork has two
functions which improve floor contact and comfort:
suspension and damping. The suspension prevents
an impact, such as one caused by a stone lying in the
3
pedelec's path, from being channelled directly into
the rider's body via the fork. The impact is absorbed
by the suspension system instead. This causes the
suspension fork to compress.

After compressing, the suspension fork returns to
its original position. If there is a damper, it
decelerates movement, preventing the
suspension system from springing back in an
uncontrolled manner and stopping the fork from
vibrating up and down. Dampers which dampen
compressive deflection movements, i.e. a
compression load, are called compression
dampers or compression dashpots.
Dampers which dampen rebound deflection
movements, i.e. a rebound load, are called
rebound dampers or dashpots.
The compression can be disabled in any suspension
fork. A suspension fork will then behave like a rigid
fork.
