If you are unable to return the bicycle at the port after locking it and pressing the “返却/RETURN” button on the terminal at the rear wheel’s top for about 5 seconds, please try the following:

(1) Is the bicycle correctly placed at the location shown in the app’s port image?
(2) Have you locked it?

If the lock and spoke are physically in contact, there may be issues with proper locking, so please try moving the rear wheel slightly with your hand and then lock it. If the issue persists, please contact our customer support center at 0570-783-677. We are available 24/7.
