Tuning module for most e-bikes/pedelecs with a Yamaha drive system.

Suitable for engine types PW-X / PW-X2 / PW-SE / PW-ST / PW-TE and PW-CE of all model years (also 2022). Only the PW, which has been out of production for a long time, and the brand new PW-X3 are not supported by the module.

Compatible with all displays. So with the side switch (display A), multi-switch (display C) and the display X.

The device is installed invisibly on the drive motor from the outside. No cables need to be damaged or modified, the module is simply plugged in and is immediately ready for use. 

No PC or smartphone is required. All settings are made conveniently via the display on the bike.

The ability to set the speed limit, the curtailment behaviour and the wheel circumference via the display are unique.

In contrast to the almost complete abolition of engine limitation with other tuning modules, this module still allows a very sporty driving style with moderate battery consumption by slightly raising the limit, eg to 32 km/h. In order to reduce the very abrupt dropping out of the engine support at the governed speed, the governed range can be expanded to double the speed range.

What is new in the meanwhile third version of the module is the possibility to set your own code for activation. In addition, no setup is required after installation. The module is immediately ready for operation.


  • New: Automatic initialization, ready for use immediately after installation.
  • The tuning can be switched on or off using the arrow keys on the control panel.
  • After switching on, the speed limit can be set freely using the arrow keys in the range of 25 - 45 km/h. The value set last is saved.
  • The tuning is always switched off after switching on the bike.
  • It is possible to set a "softer curtailment behaviour" (dynamic mode). This significantly softens the otherwise very abrupt deceleration at the speed limit. 

    dynamic mode


  • New: Individual activation code adjustable.
  • Correct display of the speed, the distance covered, as well as the average and maximum speed at all times.
  • When the tuning is active, the calculation of the remaining range takes into account the current driving style/battery consumption in addition to the charge level of the battery and the selected support level. 
  • Correct total mileage of the bike even after the tuning module has been removed, as the kilometres in the motor control are tracked by the tuning module.
  • Wheel circumference adjustable (+/-10%) to improve the accuracy of speed display and distance measurement.
