With the Impulse drive, the amount of assistance
can be increased by selecting easier gears, when
starting or riding uphill for example. The motor
produces more power when your pedalling cadence
is higher.
›
You can conveniently use the same key to lock/
unlock your battery and, where present, your frame
lock.

You can decide how you wish to put in your effort:
In the three highest gears, you can ride up to a
maximum speed of 25 km/h assisted by the motor.
You can, for example, go for a relaxed ride on the
flat with a low pedalling cadence. However, you
can also ride uphill using an easier gear and less
energy, simply by making the most of the highest
assisted speed. You should therefore either turn
the pedals more slowly (low cadence) with more
effort or turn them more quickly (high cadence)
with less effort.
The data provided is an example for the assistance function.
The data may vary depending on the model.

In contrast to a hub motor, the Impulse centre mo-
tor drive allows you to ride within the motor range
that saves the most power or, if required, the range
in which the highest output is available.
