Letter: Slipstream speeders

Published 5 January 2005

From Mike Anderson

While the reduced wind resistance and improved design of a speedbike doubles its speed, the wind resistance is by no means eliminated (4 December 2004, p 36). In motor-pacing, a cyclist rides behind a motor vehicle towing a cowling, and is almost completely shielded from the wind. The speed record for this stands at 152 miles per hour, which is almost twice as fast as Sam Whittingham achieved on his speedbike.
