What do the different symbols mean for the lock

The lock symbol in the app is to be understood as a mechanical lock. If it is open (blue), the bike is unprotected. This is the state when you ride the bike yourself. If it is closed (green), then the bike is protected. If you move it now, you will receive an alarm on your smartphone and the lock will turn red.
