This unique technical design allows


  • A variable reduction of motor power during shifting is performed based on the current gear and the specified parameters in combination with the data obtained from the system. This allows you to reduce the torque of the motor during shifting and prevents the motor from restarting before the shifting occurs. The shifting parameters are defined by the rider via the display according to individual preferred cadence and several other values of the shifting parameters.
  • Recommendation of an optimal gear based on optimal use of the efficiency of the electric motor in combination with other data collected from the system. The purpose is to conserve battery power and thus extend the riding distance on a single battery charge. This recommendation is done in the form of a graphical symbol of an arrow on the display.
  • information about the current gear to be displayed on the screen. In addition, this drive unit offers a sensorless, sinusoidal programmable controller that allows e-bike manufacturers to tweak the system's behavior by setting different parameters.
