The tuning with Bluetooth technology and mobile app for your e-bike with Bosch Gen4 motor and Smart System. Enjoy your unlimited ride and all the great functions that our SpeedBox App has to offer.

SpeedBox 1.1 B.Tuning for Bosch brings a unique connection of e-bike and mobile phone and suppresses the speed limiter on your e-bike. 

The actual speed and other riding data will be displayed correctly in our SpeedBox App - right on the display of your phone.

How does SpeedBox 1.1 B.Tuning for Bosch work?

To activate all the functions of the SpeedBox correctly, it is necessary to enter the menu after the first switching on of the e-bike after the tuning installation and switch to the circumference of the wheel of your e-bike.

Activate/deactivate the tuning before the ride (when the e-bike is standing still), not during riding!

This tuning is also easy to control. You will activate SpeedBox 1.1 B.Tuning via mobile app or directly on your e-bike’s control unit by activating the WALK assist function shortly (holding down the “-” button). Your e-bike display will show a value of 3.5 km/h (2.2 mph) and from now on you will be able to ride up to 35 km/h or more. You may change the default speed limit to any limit you want (up to 99 kph), however, to minimize the risk of error codes, we recommend not to exceed 35 km/h.

To deactivate the tuning, activate the WALK assist function shortly again (by holding down the “-” button). Your e-bike display will show a value of 2.5 km/h (1.6 mph) and the speed limit will be reset to 25 km/h. Your e-bike will then work the same as before the tuning installation.

SpeedBox was also designed for e-bikes that do not have the WALK assist function enabled, or activated. In this case, you can activate/deactivate tuning by switching between two assistance modes twice, i.e. by pressing the - + - + buttons.

When you first open the SpeedBox App, you will be asked to type in a new PIN. This PIN will be requested each time you open the SpeedBox App. After confirming the PIN, you will be asked to set a service password. Your service password will be used in case you forget the PIN or want to change it.

You can set the maximum speed limit by switching the modes from TURBO mode three levels down and then three levels up: eMTB - TOUR+ - ECO - TOUR+ - eMTB - TURBO. An actual speed limit will be displayed after that. The maximum speed of an electric assistance can be switched by activating/deactivating WALK assist function shortly or by turning the rear wheel 360°. The value of 2.5 km/h on the display corresponds with the limit of 25 km/h, 3.0 corresponds with 30 km/h, 3.5 corresponds with 35 km/h etc. The last displayed limit will be saved after 15 seconds of inactivity.

After finishing the ride, leave the e-bike on for a while until the SpeedBox finishes the "countdown" process (the riding time will continue on the display until it stops and shows the correct distance travelled) to prevent tuning detection on your e-bike.

After downloading the application and connecting your mobile phone to your e-bike you will see current data and trip parameters displayed on your phone.
