Technically, the land speed record for a bicycle is held by Bruce Bursford, who pedaled to an astonishing 208 mph in August, 1995. Bursford's record carries a caveat, however: He was sitting on a specially designed, stationary bike with helium-filled tires and a two-foot chain ring, set on rollers. With every pedal stroke, Bursford covered a theoretical 150 feet, and he rode for just 30 seconds. Other cyclists have set speed records under a variety of circumstances.
Salt Flats
Before Bursford there was Fred Rompelberg of the Netherlands, who blazed across Utah's Bonneville Salt Flats at 167 mph in 1995. Rompelberg set his record while drafting behind a special pace vehicle that created a space with zero wind resistance. Rompelberg had posted several previous speeds of well over 100 mph on the salt flats.

John Howard, the record-holder who preceded Rompelberg, rode to 152.2 mph on the Bonneville Salt Flats in 1985. Like Rompelberg, Howard rode behind a pace vehicle. In an interview, he described the experience as "terrifying and exhilarating ... like riding a pair of bumpy rollers as fast as you can possibly go where your margin of control is limited. I was turning about 120 revolutions per minute at 152 mph."
