Reliable second generation tuning chip for e-bikes with Giant motors.

SpeedBox 2.0 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 2.0 work?

You can activate the SpeedBox 2.0 tuning kit on your e-bike’s display. After pressing the WALK button, a value of 9,9 km/h (6,2 mph) appears on the display. From now on you can ride at unlimited speed - 30 km/h, 40 km/h and more than 50 km/h.

To deactivate the chip, press WALK button. 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 the chip installation.


When connecting the SpeedBox chip to an e-bike you will find connectors colored to make installation very simple. We have prepared detailed instructions and videos to make installation easy for you. Disassembly of our tuning chip 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 1 km before the chip is activated.

1) I want to buy a Giant Explore E+ 1 Pro. Will it perform like the Giant Quick-E FS 45km/h are installing the speedbox 2, because that one has "Sport Highspeed tuning 80Nm"? So do you tune it accordingly?
2) I read from the reviews (french one) that the auto mode of the 2020 is not supported ? Is this for the Yamaha motors used by Giant. Else for which type of motors is this applicable. ?
