6 Assistance by the
electric motor
6.1 Operating principle of assistance
If you switch on the assistance and start pedalling, the
motor provides assistance as soon as the rear wheel turns.
The thrust produced by the motor depends on three factors:
•
Your own pedalling effort.
The motor adapts to the force you apply. If you
pedal harder, e.g. uphill or when setting off, the
power sensor detects this and delivers more power
than if you were only pedalling gently. The assis-
tance increases proportionally if you pedal harder.
The higher the assist level you have set, the more
distinct this assistance characteristic becomes
(
➠
Chapter 5.1.2 “Buttons for power-assist level”) .
•
The level of assistance you have selected.
In the highest assist level, the motor assists you
with the highest output and therefore also uses the
most energy. If you have selected the lowest assist
level, you receive the least amount of assistance
but have the battery’s maximum range at your
disposal.

How fast you ride
When you set off on your Pedelec, the assistance
increases as you build up speed until it reaches its
maximum, just before the highest assisted speed
is achieved. The assistance then reduces automati-
cally and switches off at roughly 25 km/h, irre-
spective of the gear you are in. Depending on the
power-assist mode you are riding in, the transition
between riding with and without power assist may
seem more or less abrupt.
6.2 Assist modes
You can choose between the assist modes ECO and Sport
(
➠
Chapter 5.4.2 “Assist mode”) .
The ECO mode provides you with harmonic, gentle assis-
tance and a long range. It is advisable for beginners or
inexperienced riders to start with this mode.
In the Sport mode, the assistance is powerful. Of course,
the range is reduced as a consequence.
Within the assist modes, you can adjust the assistance by
choosing between five levels.
If you wish to make any further adjustments to the
ride characteristics of your bike, please consult your
specialist cycle shop.
