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 either has a conventional Dunlop
valve, a Presta valve or a Schrader valve.
3.1.2 Suspension
Both forks and suspension forks are fitted in this
model series. A suspension fork is based either on a
steel spring or air suspension. Unlike a rigid fork, a
suspension fork has two functions which improve
floor contact and comfort: suspension and damping.
Figure 4: Pedelec without suspension (1) and with
suspension (2) when riding over an obstacle
The suspension prevents an impact, such as one
caused by a stone lying in the bike'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. The compression
can be disabled so that a suspension fork reacts
like a rigid fork. The switch to disable the fork is
called a remote lockout.
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.

Overview
3.1.2.1 Steel suspension fork structure
Figure 5: Example showing Suntour fork
The stem and handlebars are fastened to the fork
steerer (1). The wheel is fastened to the quick
release axle (6). Other elements: the compression
setting (2), crown (3), Q-Loc (5), dust seal (6),
fork end for quick release (7), stanchion (8) and
spring (9)
3.1.2.2 Air suspension fork structure
The pedelec's fork features both air suspension and
a compression damper plus a rebound damper in
some cases.
Figure 6: Example showing Yari fork
You can see the following components in the
diagram: Air valve (1), valve cap (2) fork lock (3),
quick release (4) and rebound damper
adjuster (5) and the assembly groups: Air
suspension fork (A), compression damper
assembly group (B) and rebound damper
