BionX Bicycle - Assist Mode, Generate Mode, and Mountain Mode

16
Assist Mode / Generate Mode / Mountain Mode (where applicable)
The BionX propulsion system offers four levels of assist in the Assistance mode, and four levels of
regeneration 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 BionX motor
and measures the effort provided by the rider; this produces a natural feeling assistance from the motor.
A cadence of roughly 80 RPM is ideal, this allows for effective response from the torque sensor and
efficient use of battery energy.
When in Generate mode, the BionX 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 level of braking, 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 upon road conditions.
The Mountain mode uses an intelligent algorithm based upon the effort and the assistance level required.
The Mountain mode provides the rider with an assistance level optimized for climbing long steep hills.
Without this mode, the motor can automatically revert to an overheat protection mode thereby dimin-

through a software update of the system.
NOTE
It is recommended that the BionX system should always be turned ON while riding.
It allows the rider to use the regenerative braking feature, speedometer and odometer
functions. Speeds in excess of 60km/h (37mi/hr) are not recommended.
