You can find available bikes and reserve one from the mobile app or website for up to 10 minutes, so it will be waiting for you when you arrive.
Website App
Please note that the amount of time a bike is on reserve for you counts toward your total ride time. If you're a Pay-As-You-Go plan member and reserve a bike but aren't able to pick up the bike by the time the 10-minute reservation expires, you will still be charged the $0.08/ per minute rate
To reserve a bike, click on a station icon or a single bike icon on the map, then press the button that says “Reserve a bike at this hub” (or “Reserve this bike” for single bikes not at a station). If you change your mind, you’ll have one minute to cancel the reservation without the time counting against your daily included time (non-Pay-As-You-Go plans) or without incurring the $0.08/per minute charge as a Pay-As-You-Go member. When you arrive at the bike you've reserved simply enter your PIN, unlock and ride! Don’t forget to place the U lock in the designated holster to the left of the keypad after you unlock the bike.
