I went from 250lbs to 195lbs, so I lost 55lbs eversince started biking last year. For my 6'2" body frame, 195lbs is the ideal weight but I'm looking to lose another 10lbs. The commute is 12 miles one way (24 miles both way) to work everyday and still eat loosely. Here in Atlanta is pretty hilly and windy, so I do get a pretty well rounded cross training. So far I have logged 3000 miles from May 2006 till now. Feels great without the extra burden on body. Backpain and ankle problems went way. Clothes won't fit anymore.
