SpeedBox B.Tuning creates a unique connection between the e-bike and your mobile phone and allows you to disable the e-bike's speed limiter. During tuning, the display shows the correct speed values ​​up to a speed of 22.2 km/h. As soon as the speed exceeds 22.2 km/h, the actual speed is shown on the last two digits of the display.


- 22.3 corresponds to a speed of 23 km/h

- 23.1 corresponds to a speed of 31 km/h

How does the SpeedBox 1.0 B.Tuning work?

In order to activate all SpeedBox functions correctly, after installing the SpeedBox tuning, you must enter the menu and enter the wheel circumference of your bike.

This chip is also easy to use. Activate the SpeedBox 1.0 B.Tuning Chip in the mobile app or on the bike display. After briefly activating the WALK function (holding the "-" button) the display briefly shows 9.9 km/h (6.2 mph) after a few seconds and from then on you can drive at unlimited speed.

To disable the chip function, re-enable the WALK function (press and hold the "-" button). After a few seconds the display will show 2.5 km/h (1.6 mph) and the speed limit of 25 km/h (25 mph) will be back on. The e-bike then works exactly as it did before the chip was installed.

We also thought about e-bikes where the walk assistance (WALK function) is not available or active. In this case, you can enable and disable tuning (tuning) by double switching between the two modes, that is, by the combination of the + - + - keys.

When you start the SpeedBox app for the first time, you will be asked to set a PIN. You then use this PIN every time you start the SpeedBox app again. After selecting the PIN, you will also be prompted to set a service password, which you can use in case you forget or want to change the PIN.

If you charge your e-bike with the battery connected, you can ignore the following instructions. Because the "countdown" (deduction) process also runs hidden during the loading process. If you normally disconnect the battery from your e-bike to charge the battery, you should wait and leave the e-bike switched on until the SpeedBox has completed the "countdown" (deduction) after your ride. The running "countdown" is shown by the increasing riding time on the display of the stationary e-bike. As soon as the "countdown" has expired, the driving time is stopped and the E-Display shows the correct distance travelled. The "countdown" can be interrupted by switching off or starting the e-bike, and in no way restricts the use of your e-bike. However, it is necessary to perform regular "countdowns" (deductions) to prevent the tuning of your e-bike from being detected.

SpeedBox App for SpeedBox B.Tuning

The SpeedBox app, specially developed for SpeedBox B.Tuning, uses Bluetooth technology to connect your e-bike to your smartphone. After downloading the app and pairing the smartphone with the e-bike, you can see the current data and riding parameters on the smartphone display.
