Frequently Asked Questions

A smart Tuning Kit Volspeed V4 with an option to set a speed limit of an e-bike of your own choice. After the chip is installed, your e-bike’s display will show real data, such as maximum and average speeds, daily mileage and cruising range. In contrast to the almost complete elimination of the speed limit with other tuning modules, this module still allows a very sporty riding style with moderate battery consumption by slightly increasing the limit, e.g. to 20 mph (32km/h). For a more natural riding experience, the dynamic mode spreads the downshift over a wider speed range, the so-called "wall effect" is significantly reduced.

The tuning kit can be activated directly on your bike’s display. After pressing the ' - ' button and holding it for 3 seconds. After Tuning kit activation speed limit is displayed for 5 seconds. If you would like to change maximumm speed, just press 'Plus' or 'Minus' keys. Possible values: 16... 28mph (25... 45 km/h). Default value: 20mph (32 km/h). The set value is saved.

To deactivate the tuning kit, press the ' - ' button and hold it for 3 seconds again.

The tuning is always switched off after switching on the bike.

It is possible to set a "softer curtailment behavior" (dynamic mode). This significantly softens the otherwise very abrupt deceleration at the speed limit. Correct display of the speed, the distance covered and the average speed at all times.
