The factory calibration can only be activated by our customer service and is then available via the app. For older models with previous firmware, it can still be activated via the button – if this is the case, we advise you to update your firmware to the latest version. Download the Ampler app and follow the instructions in the app.
With the factory calibration, all sensors of your e-bike are adjusted and the functionality of all electronic components is synchronised with each other. It is not intended as a regular maintenance procedure and also resets the motor settings in the app.
CAUTION!
When factory calibrated, the engine will start by itself and the rear wheel will begin to turn. It is important that you lift the rear wheel during the entire process to avoid damage or injury.
