Tuning of E-bikes with a Brose drive

With SpeedBox you won’t be limited to the speed of 25 km/h anymore. You can freely enjoy the maximum power of your electric bike, limited only by your pedaling frequency.

SpeedBox 1.0 for Brose Specialized offers elimination of the speed limit up to the speed of 50 km/h. When in use, the actual speed will appear on your display up to 22 km/h. Then the speed indicator gets stabilized and keeps on showing the same value even at higher speeds.

SpeedBox products are thoroughly tested and we stand behind their quality. We provide lifelong warranty to all our products.
