Basic tuning kit for e-bikes with Brose motors.

SpeedBox 1.0 enables you to double the speed limit of your 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 1.0 work?

SpeedBox 1.0 for Brose stays active after being installed, so you don’t have to worry about turning it on and off.


Anyone can install the chip to an e-bike with some basic tools!  We have prepared detailed instructions and videos to make installation easy for you in the comfort of your home. Disassembly of our 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.

Why is SB not compatible with Specialized bikes if it is a simple divider?

Hi Brian. We just got the Specialized eBike and currently updating SpeedBox for Brose. I think the SpeedBox for Specialized will be available in 2 weeks :) I know it's not an answer for your question but I am not a developer. My colleague is. All I know is that the motor needs more power than standard Brose. We had to add some component on the motherboard because of it. Please contact me in 2 weeks ;)
