SpeedBox 3.3 for Yamaha (PW-X3, PW-S2, PW-XM)

A smart chip of the third generation with an option to set a speed limit of an e-bike

SpeedBox 3.3 tuning chip enables to select 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 3.3 work?

The tuning kit can be activated directly on your bike’s display.  After pressing the LIGHT button or ↑↓↑↓, a value of 9.9 km/h (6.2 mph) is displayed and from now on you will be able to ride at an unlimited speed. For displays that do not show decimal numbers, the value of 9 km/h will be displayed.

To deactivate the tuning kit, press the LIGHT button or ↑↓↑↓ again. 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 installation of the chip. For displays that do not show decimal numbers, the value of 2 km/h will be displayed.

You can set the maximum speed of an 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 an electric assistance can be switched (always rounded up by 5 km/h) by pressing LIGHT button shortly or by turning the rear wheel 360°. The last displayed limit will be saved after 5 seconds of inactivity.
