When you have successfully guided yourself to the closest bicycle, you can easily unlock it, by tapping the "scan QR code button". A camera mode will open, and you should point your phone to the QR code on the frame or on the back lock on the bicycle.
When you scan the code, you will hear the unlocking sound of the lock on the back wheel. When the pin is opened, you are ready to ride.
! Sometimes the lock pin is pressing the spoke and does not open freely. Make sure that the locking pin is free and not touching the spokes when trying to unlock!
Congratulations! The bike is now rented and you can start biking... Oh, one more thing... before you start please make sure that the bike is in good condition.
