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 diminish-
ing the assistance provided. Note that level 4 assist is more powerful than Mountain mode.
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. A rider should always remain in control and adjust their speed depending on ter-
rain, riding conditions, and their own skill level.

Turn the system on
Briefly push , the battery will beep 4 times and the bat-
tery LEDs will illuminate. After startup, the system is always
in Neutral (N / green LED) mode, indicating no motor
assist/normal bicycle operation. To turn the system off, hold
for 4 seconds and the battery will beep 5 times. After 5
minutes of inactivity the system turns off automatically.
