Reliable second generation tuning chip for your e-bike with Yamaha motor.

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.

E-bike electric assistance switches off with this chip when reaching the speed of 50 km/h.

How does SpeedBox 2.0 work?

You can activate the SpeedBox 2.0 tuning kit on your e-bike’s display. After pressing the LIGHT button, a speed of 5.0 km/h (3.1 mph) will appear on the display. After activation you will be able to ride at the speed of 50 km/h.

To deactivate the chip, press the LIGHT button again. The speed of 2.5 km/h (1.5 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 chip installation.

If you want to control your SpeedBox and lights separately, use the combination of ↑↓↑↓ buttons. By pressing the arrows in that order you can activate and disactivate SpeedBox anytime independently of the lights control.

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 arrows ↑ ↓ ↑ ↓ and SpeedBox will be activated. You can easily deactivate SpeedBox in the same way.


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.

Hello Speedbox people. I have a Giant Explore E+4GTS. 2020 model. I know the Giant sync drive sport motor is a Yamaha PW (70Nm) but I am not sure which one it is specifically? With this model of bike, there is no longer a digital display so I have a sneaky suspicion the speed box will not be compatible with my model of bike? Any help would be great, please? I would love to order your product if it's compatible?


Will this speedbox 2.0 work on LIV VALL E+ 2021 that uses Giant SyncDrive Sport motor?


Does the Speedbox overcome "walk assist". With Speedbox, will walk-assist work?

Jiří Voldán (Sales Manager)Administrator |

SpeedBox has no negative effect on the Walk assist.


When will you have a speedbox for yamaha pw se motor

Jiří Voldán (Sales Manager)Administrator |

SpeedBox 2.0 for Yamaha is fully compatible with Yamaha PW-SE.



Is this suitable for Yamaha PW-X2, 80Nm, 25km/h motor?
