Frequently Asked Questions

The tuning chip for e-bikes with the newest Bosch Gen4 motor and Smart System.

SpeedBox 1.0 enables you to suppress the speed limiter on your e-bike. When in use, the display shows the real speed up to 13.7 mph (22.2 km/h). After exceeding this speed your actual speed is indicated on the last two digits of the display.

- 22.3 corresponds to a speed of 23 km/h (1.4 corresponds to a speed 14 mph).
- 23.1 corresponds to a speed of 31 km/h (1.9 corresponds to a speed 19 mph).

This tuning chip is also very easy to control. You will activate SpeedBox 1.0 directly on your e-bike’s control by pressing WALK / + - + - buttons.

To deactivate the tuning kit, press the WALK / + - + - buttons again. Your e-bike display will show a value of 1.6 mph (2.5 km/h) and the speed limit will be reset to 16mph (25 km/h). Your e-bike will then work the same as before the chip installation.

After the activation you can rech maximum speed - 31 mph (50 km/h). Indication of tuning activation 1.6 mph (2.5 km/h) / deactivation 6.2 mph (9.9 km/h).

Display shows: readable actual speed in KM/H, correct travelled distance (after the countdown process is finished).

If you want to see correct values in MPH, you need to use SpeedBox App for that.

The "countdown" process will continue concealed during charging, therefore, if you charge your e-bike with a connected battery, you can ignore the following instructions. If you need to remove the battery from your e-bike in order to charge it, you need to wait for the SpeedBox to carry out the "countdown" process after the ride. When you stop your e-bike, the ongoing "countdown" process will be indicated by the increasing riding time. Once the "countdown" process is completed, the riding time stops and the e-bike display shows the correct distance travelled. The countdown process can be interrupted by turning off the ebike or by setting off, so it does not restrict the use of your e-bike in any way. However, you still need to have the countdown process run regularly to prevent tuning detection.

We have also prepared detailed instructions and videos to make installation easy for you. Disassembly of the tuning chip is just as easy. If you have any troubles with installation or disassembly, do not hesitate to contact us.

If you are planning to install SpeedBox on a brand-new bike, make sure you ride it for at least 1 km before the chip is activated.

Connect the male - female connectors in the direction of the lock. Do not rotate the connectors during connection!
