Description
Reliable third generation tuning chip for e-bikes with Giant 2022 Syncdrive Pro motor and RideControl Go.
SpeedBox 3.1 tuning chip enables you to suppress the speed limiter on your electric bike. After the chip is installed, your e-bike’s display shows real data, such as maximum and average speed, daily mileage, and cruising range.
How does SpeedBox 3.1 work?
The tuning kit can be activated directly on your bike’s controller. After pressing the WALK button, 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, or even more than 60 km/h.
To deactivate the tuning kit, press the WALK button 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 chip.
SpeedBox was also designed for e-bikes that do not have a classic control unit with a 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 electric assistance by switching modes three levels down and then three levels up. The actual speed limit will be displayed after that. The maximum speed can be adjusted by pressing the WALK button shortly or by turning the rear wheel 360°.
Speed limit guide:
- 1.5 km/h → 15 km/h
- 2.0 km/h → 20 km/h
- 2.5 km/h → 25 km/h
- 3.0 km/h → 30 km/h
- 9.9 km/h → 99 km/h
The last displayed limit will be saved after 5 seconds of inactivity.
Assembly
When connecting the SpeedBox chip to an e-bike, you will find color-coded connectors to make installation very simple. We have prepared detailed instructions and videos to make installation easy for you. Disassembly is just as simple. If you have any trouble 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 1 km before activating the chip.
