SpeedBox 3.1 Yamaha (PW-X3, PW-S2)
A smart chip of the third generation with an option to set a speed limit of an e-bike.
SpeedBox 3.1 tuning chip enables to select the speed limit of your own choice. After the chip is installed, your e-bike’s display will show real data, such as maximum and average speeds, daily mileage and cruising range.
How does SpeedBox 3.1 work?
The tuning kit can be activated directly on your bike’s display. After pressing the LIGHT button or ↑↓↑↓, a value of 99 km/h (62 mph) is displayed and from now on you will be able to ride at an unlimited speed.
To deactivate the tuning kit, press the LIGHT button or ↑↓↑↓ again. The value of 25 km/h (16 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 installation of the chip.
You can set the maximum speed of electric assistance by changing modes three levels down and then three levels up. An actual speed limit will be displayed after that. The maximum speed of electric assistance can be switched by pressing LIGHT button shortly or by turning the rear wheel 360°. The last displayed limit will be saved after 5 seconds of inactivity.
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.
