The system is switched from rim magnet logic to spoke magnet or sensor logic. The bike then operates with a separate tuning sensor. This can be particularly useful if activation is not to be achieved solely through software, but rather via the sensor position.
Benefits
The tuning logic is located in the sensor.
Activation is possible at every start if the magnet is in front of the sensor.
The maximum speed can be adjusted.
Suitable for users who prefer a sensor-based solution.
Disadvantages / limitations
