Overview
3.1 Description
3.1.1 Wheel
Figure 3: Visible wheel components
1Tyres
2 Rim
3 Spoke
4 Spoke nipples
5Hub
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
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: 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.

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 Disc brake
Figure 7: Brake system with disc brake – example
1 Brake disc
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 lines 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.
3.1.3.2 Rim brake

5 Front wheel rim brake
Figure 9: 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.

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.
Figure 11: Diagram of mechanical drive system
1 Direction of travel
2 Chain
3 Rear chain wheel
4 Front chain wheel
5 Pedal
The pedelec also has an integrated electric drive
system.
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 pre-set level of assistance
determines the motor output.
The pedelec does not have a separate emergency
shut-off button. 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.
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.
The electric drive system is made up of
7 components:

3.1 Integrated battery
3.2 Frame battery and/or
3.3 Pannier rack battery
4 Rear light
5Electric gear shift (alternative)
6Motor
7 A charger which is designed for the battery.
A push assist system can be activated. The speed
depends on the selected gear. The push assist
continues to drive the pedelec as long as the rider
presses the push assist button on the handlebars
The speed can be a maximum of 6 km/h in this
case. The electric drive system stops when the
push assist button is released.
3.1.5 Rechargeable battery
Bosch batteries are lithium ion batteries which are
developed and manufactured to the latest
technical standards. Each individual cell is
protected by a steel cup and encased in a plastic
battery housing. These batteries meet and exceed
applicable industrial safety standards. The battery
has an internal electronic protection circuit, which
is specifically designed for the charger and the
pedelec. 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.
