How do I set up and activate or deactivate the premium 'Lock' function?

After you have purchased the premium function from the Google Play Store or the Apple App Store, the eBike Lock feature will appear in the eBike Connect app under My eBike.

You can use the My eBike > Lock function menu item to set up the function and activate/deactivate it. To do this, move the slide control to the right or left.
