The wheel revolves slowly enough to allow riders to board or disembark without its stopping. The wheel is stopped for people in wheelchairs or the elderly. During the 30-minute revolution, riders are treated to a breathtaking view of the city of London. On a clear day, one can see as far as 25 miles (40 kilometers) in all directions. It has become London's no. 1 paid-for attraction, with about 10,000 people visiting each day.
There are 32 capsules, representing the 32 boroughs of London. Each is airconditioned and has bench seating. Eight hundred people can ride at once.
