Basic tuning kit for your e-bike with Brose Specialized motor.

This tuning kit enables you to deactivate the speed limiter of your e-bike.

When in use, the actual speed of 22 km/h will appear on your display. Then the speed indicator gets stabilized and keeps on showing the same value even at higher speeds.

SpeedBox 1.0 enables to double the speed limit of an e-bike from the original 25 km/h to 50 km/h.

The motor’s electric assistance switches off when reaching 50 km/h.

How does SpeedBox 1.0 work?

SpeedBox 1.0 for Brose stays active after being installed in your bike, 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 the installation, 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.

Which speed box?


Hello Speedbox.
How about newer Firmware in 2019 Turbo Levo (where the wheel circumference change has been prevented). TCU Firmware is then 2.026 and mission control shows this as 1A.B.0. Will Speedbox still work?
