Bikes can be returned to any station with an open rack or public bike rack within the service area ($2 fee)– you don't have to bring it back to the location where you picked it up.
When locking a bike to a BIKETOWN station or public bike rack, insert the U-lock into the two designated slots on the right side of the back wheel, pushing the lock in from right to left. Wait until you feel the click and see the "Thank You" screen on the LCD display to make sure it's locked. If the screen flashes red and you hear beeping, it means you haven't properly locked the bike. If you cannot get the lock to engage, roll the bike slightly forward or backward to ensure a wheel spoke isn’t blocking the lock.
Always lock the bike to a bike rack or secure pole. Leaving a bike locked only to itself results in a $5 fee.
