Motor assistance above 25 km/h

The tuning module ensures that the motor support of your eBike is still active at speeds above 25 km/h.

Tuning can be activated and deactivated

You can use a clever on/off sequence for your eBike to optimize the tuning

  • activate, deactivate or
  • only once for the current ride. After switching off the eBike, the tuning is then gone.

The activated tuning and the selected speed display are signaled via the speedometer when the eBike is switched on. This means you always know which mode is active.

Real speed modified readable

To ensure that the motor assistance also works above 25 km/h, a lower speed than the actual speed is displayed when tuning is activated:

Below 22 km/h, the real speed is displayed.

Above 22 km/h, mentally move the decimal point displayed in the speedometer one place to the right. The leading 2 on the far left then no longer has any function.

Example: A speed of 38 km/h is displayed as: 23.8 km/h

Advantage: The verifiable average speed always remains inconspicuously below 25 km/h!

Maximum support speed adjustable

You can set the speed up to which the motor should provide assistance. This ranges from 31 to 50 km/h in steps of 1 km/h. The standard setting for this tuning module is 45 km/h.

Once the cut-off speed has been reached, the motor assistance is gently reduced.

The speed remains visible even above the set switch-off speed.

Correct display of kilometers driven

Wheel revolutions omitted due to tuning are added at the end of the ride. The speedometer then shows the exact distance traveled.
