Main Product Information

SpeedBox 2.0 for Yamaha PW is a revolutionary tuning kit which suppresses the speed limiter of your electric bike. After the tuning kit is installed your e-bike’s display shows real data, such as maximum and average speed, daily mileage and cruising range only in the kilometrage setting, if you are using miles your data will be desplaid half value.

E-bike electric assistance switches off with this tuning kit when reaching the speed of 31 mph (50 km/h).

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]

You can activate the SpeedBox 2.0 tuning kit on your e-bike’s display. After pressing the 'LIGHT' or '↑ ↓ ↑ ↓' buttons, a speed of 3.1 mph (5.0 kph) will appear on the display. After activation you will be able to ride at the speed of 31 mph (50 kph). Display shows: actual values (only in km/h)

To deactivate the chip, press the 'LIGHT' button again. The speed of 1.5 mph (2.5 kph) will appear on your display and the speed limit will reset to 15 mph (25 kph). 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 deactivate SpeedBox anytime independently of the lights control.

This tuning kit is compatible with all E-Bikes; E-MTB; E-Mountain Bikes that have YAMAHA PW motor only.

If your Yamaha 2017-2022 e-bike is with YAMAHA PW-SE / PW-X / PW-TE / PWX2 / motor you would need this tuning kit - Speedbox 3.0 for Yamaha

When connecting the SpeedBox tuning kit 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 0.6 miles (1 km) before the chip is activated.
