The tuning kit can be activated directly on your bike’s controller. After pressing the WALK / '+ - + -' buttons, a value of 6.2 mph (9.9 km/h) is displayed and from now on you will be able to ride at a speed of 25mph (40 km/h), 30mph (50 km/h) and even more than 37 mph (60 km/h).
To deactivate the tuning kit, press the WALK button again. The value of 1.6 mph (2.5 km/h) will appear on your display and the speed limit will reset to 16mph (25 km/h). Your e-bike will then work the same as before installation of the chip.
SpeedBox was also designed for e-bikes that do not have a classic control unit with Walk button. 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 switching modes three levels down and then three levels up. An actual speed limit will be displayed after that. The maximum speed of an electric assistance can be switched by pressing WALK button 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.
In case of updating the software of your e-bike, uninstall SpeedBox from the e-bike first, update the software and reinstall SpeedBox. Tuning kit is compatible with Giant software up to June 2023. Versions beyond this date are not supported
