What do I do if I have closed the trip but it appears that it is still open?

In this case, close the application and open it again; this way it will be updated and it will show that the trip is closed correctly. 

If, after restarting the app, it still shows that you are on a trip, it is most likely that the bike has been incorrectly docked. Please refer to the question "I can't manage to lock my bike properly" in this section.
