The tuning for e-bikes with the newest Bosch Gen4 motor and Smart System + Rim Magnet. Get the most of your e-bike!
SpeedBox 1.2 for Bosch enables you to suppress the speed limiter on your e-bike.
If you want to see correct speed and all riding data during your ride, we recommend choosing SpeedBox 1.2 B.Tuning for Bosch - you can see the real values in our SpeedBox App – right on the display of your phone.
How does SpeedBox 1.2 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!
You will activate the SpeedBox 1.2 tuning 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. 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.
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 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 bike on after finishing the ride until a value of 0.0 km/h is displayed. During this process the remaining time will be displayed. Then it is safe to turn off your bike and you can start looking forward to your next trip. Do not remove the display to lock the e-bike until SpeedBox finishes the "countdown" process.
Assembly
We use original connectors for the production of SpeedBox products ensuring that the installation process is very simple and the SpeedBox is connected properly. We have also prepared detailed instructions and videos to make installation easy for you. Disassembly of the SpeedBox is just as easy. If you have any troubles with installation or disassembly, do not hesitate to contact us.
If you are planning to install SpeedBox on a brand-new bike, make sure you ride it for at least 10 km before the tuning is activated.
Important:
Connect the male - female connectors in the direction of the lock. Do not rotate the connectors during connection!
