Operation

If you switch on the assistance and start pedalling, the
motor starts as soon as the rear wheel is turning.
The level of thrust delivered 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 set, the more pro-
nounced this assistance characteristic becomes.

The level of assistance you have selected.

In the highest assist level (POWER + SPORT), the
motor delivers the highest output and therefore
also uses the most energy. With the SPORT as-
sist level, the motor produces slightly less power.
If you have selected ECO, you receive the least
amount of assistance but have the battery's maxi-
mum 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. Then it reduces automatically and
switches off at roughly 27,96 mph, irrespective of
the gear you are in. Depending on the power-assist
