SpeedBox 1.3 enables you to double the speed limit of an e-bike from the original 25 km/h to 50 km/h. When applied, the actual speed will be displayed in half values. The display also shows your trip and other aspects of your ride.

How does SpeedBox 1.3 work?

SpeedBox 1.3 tuning kit can be activated on the e-bike’s control unit. After pressing the LIGHT button, the active lights icon will be displayed shortly after which you will be able to ride at a speed of 50 km/h.  The chip is deactivated by pressing the LIGHT button again.

By attaching the Light cable for Bafang, you can use the SpeedBox and your lights at the same time.


When connecting the SpeedBox chip to an e-bike, connectors are coloured to make installation very simple. We have prepared detailed instructions and videos to make installation easy in the comfort of your home. Disassembly of our tuning chip is just as easy. If you have trouble with the 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.
