6Valve
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 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.
3.1.2.1 Rigid fork
Rigid forks do not feature suspension. They transfer
the used muscle and motor power to the road to
optimum effect. Pedelecs with rigid forks consume
less energy on steep roads and have a greater range
than pedelecs with adjusted suspension.
3.1.2.2 Suspension fork
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. The suspension prevents
an impact, such as one caused by a stone lying in the
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.
Figure 4: Without suspension (1) and with suspension (2)
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.

Overview
3.1.3 Brake system
Every pedelec has a hydraulic brake system. The
brake fluid is in a closed hose system. If the rider
pushes the brake lever, the brake fluid activates
the brake on the wheel.
The pedelec has either:
• a rim brake on the front and rear wheels
• a disc brake on the front and rear wheels or
• a rim brake on the front and rear wheels and an
additional back-pedal brake.
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.
3.1.3.1 Rim brake

1 Rear wheel rim brake
2 Brake booster
3 Brake lining
4Handlebars with brake lever
5 Front wheel rim brake
Figure 10: Rim brake locking lever, closed (1) and open (2)
The rim brake stops the wheel moving when the
rider pushes the brake lever, causing two brake
linings, positioned opposite one another, to be
pressed onto the rims. The hydraulic rim brake
features a locking lever. The rim brake locking
lever is not marked with any lettering. Only a
specialist dealer may set the rim brake locking
lever.
3.1.3.2 Disc brake

1Brakedisc
2 Brake calliper with brake linings
3Handlebars with brake lever
4 Front wheel brake disc
5 Rear wheel brake disc
On a pedelec with a disc brake, the brake disc is
screwed permanently to the wheel hub.
The brake lever is pushed to increase brake
pressure. The brake fluid is used to transfer
pressure through the brake cables to the cylinders
in the brake calliper. The braking force is boosted
by a speed reduction and applied to the brake
linings. These apply the brake disc mechanically.
If the brake lever is pushed, the brake linings are
pressed against the brake disc and the wheel
movement is decelerated until it comes to a stop.

ABS is an added function in some pedelecs.
BOSCH ABS
The rear wheel brake function does not depend on
the anti-blocking system (ABS) functioning
correctly.
When the brakes are applied, the ABS function
detects critical slippage thanks to the wheel speed
sensors on the front and rear wheels. The ABS
limits slippage on the front wheel by reducing
brake pressure there, thus stabilising the wheel.
Once the wheel has been stabilised, the wheel is
brought to the blocking limit by building up
pressure selectively.
If the wheel blocks again, the pressure is reduced
again. This process is repeated to keep the wheel
at its limit of traction, thus making optimum use of
the coefficient of friction between the tyres and the
road surface.
The ABS stops when one of the following events
occurs:
• The buffer chamber in the ABS control unit is filled
completely.
• The pedelec is stationary.
• The rider releases the brake.
Besides slippage, the ABS also detects when the
rear wheel is raised during full braking. The ABS
thus counteracts a flip-over during extremely hard
braking manoeuvres.
If the battery is low, the ABS deactivates the motor
assistance first. However, the electric drive sys-
tem, including the display, lighting and ABS, will
remain active until the battery is empty. The elec-
tric drive system the ABS will not switch off until
the battery has almost fully discharged. The brake
system itself remains functional. The ABS is not
active if there is no battery on the pedelec or the
battery is empty.
The indicator lamp lights up for about 5 seconds
before the system switches off completely. The
ABS indicator lamp will go out if the ABS is
unavailable.
