Rotation sensor or power pedal sensor?

An e-bike may be equipped either with a rotation sensor or a force pedal sensor. The force pedal sensor registers how much force the cyclist puts on the pedals and the motor automatically adjusts the support accordingly. Those who pedal firmly and vigorously will receive considerable support from the motor. Those who pedal only lightly will receive less support.

A rotation sensor registers the rotation of the bottom bracket and measures the number of times your pedals rotate within a certain period of time. In other words, the pedaling frequency. From a certain frequency, the motor knows you are cycling and switches on the pedal assistance. Specifically, with our bikes, this means that the motor provides assistance as soon as the bottom bracket makes one complete revolution.

A motor with a power pedal sensor is usually more expensive than one with a rotation sensor.
