How does it work ?
citybike is very simple. Sign up for either a day, week or annual membership (either online or by calling 0151 233 3002). Once you've signed up as a member, you'll receive a membership number and PIN. Simply key in your membership number and PIN at any of the stations and select a bike to rent. Then press the flashing button on top of the lock box to release the bike. You can return the bike to any station, not just the one you rented it from.
