Benefits:
Uses the original rim magnet—no additional speed sensor required.
Easy installation with a wire clamp directly on the motor.
Invisible after installation.
Automatic calibration, ready for immediate use after installation.
Controlled via the bike's control unit —no smartphone required.
Features:
- Can be conveniently turned on/off using the buttons on the control unit.
- Adjustable speed limit between 25–45 km/h. The last setting is saved.
- Tuning is always deactivated when the bike is turned on.
- Option to enable a "softer speed limit behavior" (Dynamic Mode), significantly smoothing out the otherwise abrupt cut-off at the speed limit.

Notes:
- Installing this module requires removing the motor. Specialized knowledge is necessary. If you lack expertise, have the tuning installed by a specialist.
- The tuning is mounted at a predefined location on the motor. Some bike models may not have enough space, making installation impossible.
- With tuning activated, the speed displayed above 21 km/h and the distance measured will be lower than actual. The odometer will show a reduced mileage after using the tuning.
