In Tulsa: Make sure your bike is locked to a bike rack (or a public pole where is is safe and not obstructive) in the service area. You must park This Machine bikes within the service area, indicated by the border on the map in the app. You may face warnings or fines if you do not.
In Broken Arrow: This Machine bikes must be returned to This Machine Stations. If you're stopping somewhere on your ride, feel free to park and lock your bike there while you're there, but the city asks that bikes that are not being used are returned to a designated This Machine rack.
After manually locking the bike to a rack or public pole, hit the "end trip" button in the app, and follow all of the on-screen instructions. Your ride will not be ended until you have followed all of the steps in the app, including taking a photo of the locked bike. For more information on how to lock the bike or end your trip, watch the videos above.
