Main Product Information

SpeedBox 3.0 for Yamaha is a revolutionary tuning kit which suppresses the speed limiter of your electric bike. After the Tuning kit is installed, your e-bike will be derestricted and you will reach speeds up to speeds up to 31 mph (50km/h) or over, depending your pedaling speed and frequency. Your e-bike’s display will show real data, such as maximum and average speeds, daily mileage and cruising range.

Note: The Speedbox App is an application specially designed for Speedbox B. Tuning products only. With a non-Bluetooth Speedbox product like this one, the Speedbox App is unavailable.

SpeedBox 3.0 B. Tuning for Yamaha PW-SE / PW-X / PW-TE / PW-X2 motors

The tuning kit manipulates the speed signal without altering the motor's power relative to pedaling speed. This guarantees a smooth motor control without speed limit interruptions. Depending on a tuning kit, some determine when assistance stops, while others remove the restriction entirely for continuous support. However, the achievable speed mostly depends on the eBike model. Achievable speed can be calculated using a simple formula:

Speed = Cadence [rpm] * Wheel circumference [mm] * Front Chainring Teeth / Rear Chainring Teeth * 60 [min/h] / 1.000.000 [mm/km]

SpeedBox 3.0 chip is activated on your e-bike’s display by pressing the one of the sequence 'LIGHT' / '↑ ↓ ↑ ↓' / '+ - + -', a value of 62 mph (99 km/h) 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 16 mph (25 km/h) will appear on your display and the speed limit will reset to 16mph (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 by changing modes by switching 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.

In case of updating the software of your e-bike, uninstall SpeedBox from the e-bike first, update the software and reinstall SpeedBox.
