Firmware Updates

Updating your eBike’s motor firmware may block or disable your tuning kit.

We recommend avoiding firmware updates 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.
