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.
