What does this Tuning Kit do? 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.

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 manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support.

However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula. Speed = Cadence [rpm] Wheel circumference [mm] Front Chainring Teeth / Rear Chainring Teeth 60 [min/h] / 1.000.000 [mm/km]. The tuning kit can be activated directly on your bike's display.

After pressing the arrow keys'????' starting from the support level'High - STD - Hight - STD - Hight'. After Tuning kit activation speed limit is displayed for 5 seconds. If you would like to change maximumm speed, just press arrows button'Up' or'Down' keys. Default value: 20mph (32 km/h). The set value is saved.

The value will be saved if you will not press any button for 5 seconds. To deactivate the tuning kit, press the'???? 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. Is this Volspeed the right tuning kit for my bike?
