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 / WALK UP, 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 / WALK UP. 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.

All fitted as it should

The bike had some mode on that prevented the speedbox working. Once this mode was switched off all was good.

There has been a recent firmware update on the Fathom E+3 which means the Speed box 2 no longer works as the operation of the walk assist button if different. Is there a way or plan to update the firmware in the Speed box or is it now redundant?

Hi there!
I Installed the Giant Speedbox 2.0 (2nd after retour) on my Giant Trance X E+ 2 2021. And everythime i got Error 2 (Ride Control Display Error). Without Speedbox, it is working fine.
Did Giant change the PIN Assignment on the 2021?
I would be grateful for Help!

I’ve just fitted a speed box 2 giant into my 2020 trance e+ turned the power back on and like the information said I pushed the walk
Button and the power lights turned on going from 1 to 5 then back to 1 and up to four but it still hasn’t aloud me to go above 25kmh is there something else I should be doing


Will this work on the new 2021 Giant Roam E+?
It has the Giant SyncDrive Core, powered by YAMAHA, which I believe is the Yamaha PWseries CE motors 50nm

Thanks for your help


I installed the Speedbox 2 on a Giant Fathom E+3, XL PWR.
This bike has no display, just the Ride Control One.
When I try to connect the Speedbox App with the bike, it does not work.
The Ride Control App from Giant works fine.
Any recomendation?

SpeedBox app is compatible with Bosch motors only, sorry.
