Tuning of E-bikes with a Bosch drive - Bosch Motor - Gen 4 - Smart System (Rim Magnet)

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 3.0 for Bosch is the tuning model compatible with Bosch motors of 2nd, 3rd and 4th generation. This product shows the real values in km/h on the e-bike display and also allows you to set your own maximum speed limit. 

For the latest generation of the motors with Bosch Smart System, we have developed SpeedBox 1.1 for Bosch and SpeedBox 1.2 for Bosch, which is also compatible with the rear wheel valve magnet (so-called Rim Magnet).

Would you like to keep track of your rides? Check out our SpeedBox 3.0 B.Tuning for Bosch, SpeedBox 1.1 B.Tuning for Bosch and SpeedBox 1.2 B.Tuning for Bosch models equipped with Bluetooth to pair your e-bike with our SpeedBox App.

If you’re not certain about which one to choose, you can use our simple Buyer’s Guide.

All SpeedBox products are thoroughly tested. All products purchased on our e-shop are covered by a lifetime warranty.
