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 Impulse 2.0 and SpeedBox 1.0 for Impulse EVO RS series offers elimination of the speed limit up to the speed of 50 km/h, but it shows half values on the display.

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