Tuning of E-bikes with a Shimano 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 pedalling frequency. Below you will find several of our products designed for the Shimano Steps motors.
If you’re not certain about which one to choose, you can use our simple Buyer's Guide.
