If a Classic Metro Bike Share station is full, you must find an open dock at another station and return the bike. If you need some extra time to do so, you can get an extra 15 minutes on your trip by following the instructions on the kiosk screen. The best way to find your nearest available dock is to use the app.
Pro Tip: Always check the app or website station map before your ride to make sure there is a bike and dock available.
