Tuning of E-bikes with a Yamaha 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 2.0 for Yamaha is a reliable tuning chip of the second generation. What exactly does this mean? The speed limit of 25 km/h is completely eliminated with real values shown on the bike’s display.

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