How to Turn Tuning On/Off

Press and hold the minus (–) button on your controller for 3 seconds to toggle tuning on or off.

The kit is completely undetectable – simply remove before getting your bike serviced.


Important: Firmware 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.

Please note: A blocked tuning kit due to a firmware update is not covered under warranty.
