Speedbox Yamaha 3.4 B-tunning Speed Increasing Device

The tuning kit can be activated directly from the mobile application SpeedBox App or on your e-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, use SpeedBox App again or 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 installation of the chip. You can set the maximum speed of an electric assistance in SpeedBox App or 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 by pressing LIGHT button shortly or by turning the rear wheel 360°. The last displayed limit will be saved after 5 seconds of inactivity. A new feature in this SpeedBox version is the possibility of activating the double-click function in SpeedBox app. By activating this function, the lights become independent of tuning. By double-clicking on the LIGHT button, the lights will flash, and the tuning will turn on. If you double-click on the button again, the tuning will turn off and the e-bike will work the same as without a chip.
