Bicycle Travel
Nicknamed "Boris bikes" after the former mayor, dedicated cyclist, and current Prime Minister Boris Johnson, a 24-hour bike-rental program called Santander Cycles enables Londoners to pick up a bicycle at one of more than 750 docking stations and return it at another. The first 30 minutes are free, then it's £2 for every 30-minute period thereafter. There is also a £2-per-day access charge. You pay at the docking station, using credit or debit cards only (cash is not accepted)—simply follow the instructions on the touch screen and away you go.
