You can find available bikes and reserve one from the Lyft or BIKETOWNpdx 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 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 according to your plan’s 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 incurring your plan’s per minute charge. When you arrive at the bike you've reserved simply scan the QR code on the fender of the bike, unlock and ride!
