Our tuning chips allow you to unlock the speed limit of your e-bike, so the engine will support you even above 25 km/h. You will be able to enjoy riding at any speed that will depend only on the frequency of your pedaling.

SpeedBox 1.2 for Bafang and SpeedBox 1.3 for Bafang both enable you to double the speed limit of an e-bike from the original 25 km/h to 50 km/h. When in use, the display shows the actual speed up to 23 km/h.

Would you like to keep track of your rides? SpeedBox 1.2 B.Tuning for Bafang and SpeedBox 1.3 B.Tuning for Bafang are also equipped with Bluetooth technology, which enables pairing your e-bike with our SpeedBox App mobile application. After downloading the application and connecting your phone to your electric bike, you can track the current data and riding parameters on your phone.

Before ordering the product, please check the number of pins on the speed sensor.
