What about the guy in the 70's that was paced by a mid 50's chey with a big block, that had the pace car clear the mile before the bike entered so it was only his pedaling for power for the full mile? I think his average speed was in the 150 range.
Tell us about it. It seems to be unknown to Wikipedia.
"Allan Abbott, a cycling enthusiast and motorcycle racer, elevated the motor-paced bicycle speed record at the Bonneville Salt Flats, reaching 223 km/h (139 mph) in 1973. John Howard, Olympic cyclist and Ironman triathlon winner, reset the record to 244 km/h (152 mph), also at the Bonneville Salt Flats, on 20 July 1985."
edit: Abbott was the one with the '55 Chevy, but your story of him doing the mile unpaced will need some evidence.
