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 has either
• a classic Dunlop valve,
• a French valve (also known as a Sclaverand or
Presta valve) or
• a Schrader valve.
3.1.2 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
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: Pedelec 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.

About these operating instructions
Negative deflection
Sag is the percentage of total deflection that is
compressed by the rider's weight, including
equipment (such as a backpack), their seating
position and frame geometry. Sag is not caused
by riding.
The pedelec rebounds at a controlled speed if it is
optimally adjusted. The wheel stays in contact
with the ground when passing over bumps
(blue line).
The fork head, handlebars and rider broadly follow
the terrain when riding over bumps. The
suspension motion is predictable and controlled.
Figure 5: Optimum fork riding performance
When optimally adjusted, the fork counteracts
deflection, stays higher in its deflection range and
helps the rider to maintain speed while riding on
hilly parts of terrain.
Figure 6: Optimum fork riding performance on hilly terrain
When optimally adjusted, the fork deflects quickly
and unhindered when the bike hits bumps and
absorbs a bump. Traction is retained (blue line).
The fork responds quickly to the bump. The
headset and handlebars rise slightly when
absorbing a bump (green line).

About these operating instructions
3.1.2.2 Steel suspension fork
The stem and handlebars are fastened to the fork
steerer. The wheel is fastened to the axle.
Figure 8: Suntour steel suspension fork as an example
3.1.3 Brake system
The pedelec features 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 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 Disc brake
Figure 9: Brake system with disc brake – example
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.

Overview
3.1.4 Electric drive system
The pedelec is driven by muscle power applied to
the chain drive. The force which is applied by
pedalling in the direction of travel drives the front
chain wheel. The chain transmits the force onto
the rear chain wheel and then onto the rear wheel.

3 Rear chain wheel
4 Front chain wheel
5 Pedal
The pedelec also has an integrated electric drive
system. The electric drive system is made up of
5 components:

4Rechargeable battery
5 A charger designed for the battery.
3.1.5 Motor
Figure 12: Motor
As soon as the required muscle power from the
rider pedalling passes a certain level, the motor is
activated gently and assists the rider's pedalling
motion. The motor force is determined by the set
level of assistance. The system performance is
determined using the pedal assistance settings on
the control panel.
The pedelec does not have a separate emergency
stop or emergency shut-off button. The motor
switches off automatically as soon as the rider no
longer pedals, the temperature is outside the
permitted range, there is an overload or the shut-
off speed of 25 km/h has been reached.
When you step on the pedals again and the speed
drops below 25 km/h, the system starts again
A push assist system can be activated. The speed
depends on the selected gear. The rider slows the
pedelec down to their own pace by holding the
pedelec more firmly while pushing.

3 Charge level (battery)
The lithium ion battery has an internal electronic
protection circuit, This battery is specifically
designed for the charger and pedelec motor. The
battery temperature is monitored at all times. The
battery is protected against deep discharge,
overcharging, overheating and short circuit. In the
event of a hazard, a protective circuit switches the
battery off automatically. If the pedelec has not
been moved for 10 hours and no button has been
pressed on the control panel, the electric drive
system and the battery automatically switch off to
save energy. The same applies if the battery level
falls below 30%, the pedelec has not been moved
for 3 hours and no button has been pressed on the
control panel.
The battery's service life can be extended if it is
well maintained and, above all, stored at the
correct temperatures. The charging capacity will
decrease with age, even if the battery is
maintained properly. If the operating time is
severely shortened after charging, this is a sign
that battery has reached the end of its useful life.
When the battery is switched on, the battery level
indicator shows the start animation. The LEDs
then briefly indicate the charge level of the
battery.
If the battery is switched on, the charge level can
be queried by briefly pressing the On-Off button.
