How does SpeedBox 3.0 work?
The tuning kit can be activated directly on your bike’s display. You will activate SpeedBox 3.0 by activating the WALK assist function shortly, a value of 9.9 km/h (6.2 mph) is displayed and from now on you will be able to ride at a speed of 40 km/h, 50 km/h and even more than 60 km/h.
To deactivate the tuning, activate the WALK assist function shortly again. The value of 2.5 km/h (1.6 mph) will appear on your display and the speed limit will reset to 25 km/h. Your e-bike will then work the same as before installation of the tuning.
SpeedBox was also designed for e-bikes that do not have a classic control unit with WALK assist function. In this case you can just use the combination of + - + - buttons and SpeedBox will be activated. You can easily deactivate SpeedBox in the same way.
You can set the maximum speed of an electric assistance by changing modes: Turbo - 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 1,5 km/h on the display corresponds with the limit of 15 km/h, 2 km/h corresponds with the limit of 20 km/h, 2,5 corresponds with 25 km/h, 3,0 corresponds with 30 km/h, 9,9 corresponds with 99 km/h etc. The last displayed limit will be saved after 5 seconds of inactivity.
When using SpeedBox 3.0 with Bosch motors of the 4th generation (produced in 2020 or later) it is necessary to 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 in minutes. Then it is safe to turn off your bike and you can start looking forward to your next trip.

Disassembly of our tuning chip is just as easy. If you have any troubles with installation or disassembly, do not hesitate to contact us.
