SpeedBox 3.3 tuning chip enables 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 3.3 for Giant work?

You will activate the SpeedBox tuning directly on your e-bike’s control unit by activating the WALK assist function shortly. Do not activate while riding. Your e-bike display will show a value of 5.0 km/h (3.1 mph) and from now on you will be able to ride up to 50 km/h. You may change the default speed limit to any limit you want (up to 99 km/h), however, to minimize the risk of error codes, we recommend not to exceed 50 km/h.

To deactivate the tuning, activate the WALK assist function shortly again. Do not deactivate while riding. 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 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, 5.0 corresponds with 50 km/h etc. The last displayed limit will be saved after 5 seconds of inactivity.

After finishing the ride, leave the bike on 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.
