Unlock the full potential of your Yamaha powered eBike with this eBike tuning kit. Works seamlessly with any Yamaha PW-X3, PW-S2 or PW-XM motor. It removes the 15mph or 20mph factory speed limit, allowing you to enjoy faster, unrestricted rides. Once fitted, it can be switched on or off at anytime using the handlebar controls.
With this premium bluetooth version, you can control the kit using your phone as well as track rides in real time. If your bike has an Interface X controller without speed readings, we highly recommend this version.

Software Updates
Software Updates
Updating your eBike’s motor firmware may block or disable your tuning kit.
We recommend avoiding firmware updates especially through service centres unless absolutely necessary. Most updates are optional, and a working eBike doesn’t usually need one.
Keep in mind:
✔ Firmware upgrades can remove tuning compatibility
✔ Tuning is only guaranteed to work with the firmware version available at time of purchase
✔ A blocked tuning kit due to a firmware update is not covered under warranty
If you’re unsure, reach out before updating. We’re here to help you keep your ride running exactly how you like it.
