For every trip exceeding trip time, overage fees will accumulate at a rate of $4 for each 30 minutes of additional trip time. To avoid an overage charge, before your 30 or 45 minute trip is up, dock the bike and unlock another to continue riding.
Select "I Have a Pass" at a station kiosk and tap "Time Credit" to receive an additional 15 minutes of trip time to travel to a new station. Using the app? Tap the full station on the map to request a 15 minute time credit.
