You can sign up for a membership through this website. Please see the Annual Membership page for more details. Your membership starts immediately upon purchase and you can start riding right away – you don’t need to wait for your bike key to arrive in the mail! Download the Citi Bike app, log in, and when you're at a station, select the station on the map and push Unlock a Bike. If you don't want the app, just go to the kiosk, select “Rent a bike” and insert the credit card that is associated with your account. We’ll be able to identify you as a member and give you a one-time-use ride code. Once you get a ride code, type it into the keypad on a dock with an available bike to unlock the bike. To ride again before you get your bike key, insert the same credit card to get a new ride code.
