Assist Mode / Generate Mode

The Bionx propulsion system operates in four assist levels in the assistance mode, and in four charging
levels in the generate mode. In the assistance mode, your pedaling is assisted proportionally by an
electric motor that drives the rear wheel. A torque sensor is located on the axle of the electric motor and
measures the effort provided by the rider; this produces natural feeling assistance from the motor.
When in generate mode the electric motor functions as a generator and recharges the battery. When
going downhill, you can regulate your speed by varying the generate level. This generate function
provides a certain braking effect, however it does not replace legally required brakes. If the rear brake
lever is pulled, the drive system automatically enters generate mode. The range can therefore be extended
up to 15%, depending on the road conditions.
