Virtual cycling, real calorie burn

Philadelphia, Pa. - July 18, 2008

The bikes simulate a real road race. You can choose different courses, like riding through the mountains or cruising the palm-tree lined Florida coast. You can race friends or other virtual riders and track your progress online.

Gary Hill, of West Chester, Pennsylvania, said the bikes spice up his workout. "It really motivates me because I'm racing other riders, I just went up a hill and blew right by them so I love it."

'Expresso' bikes can be found at the 'Sporting Club at the Bellevue' and several other gyms in Philadelphia
