62 miles per hour on a bicycle is fast in anyone's book. Anytime I've done 60+ mph, it was on a motorcycle - wearing full road race leathers and a real helmet. Impressive stuff. I wonder if they ponder the integrity of carbon forks while touching 60 mph. Carbon steerer tube - don't fail me now.
I never seem to break 45 mph on my road bike - and trust me, I've tried. I need to find a bigger hill or stop wearing Hefty garbage bags as a cheap jacket. The flapping may be slowing me down some. The flapping noise does help warn pedestrians of my impending closing distance and wet brakes however.
I have hit 51 mph on a mountain bike - my personal record. Long, steep dirt road with assorted loose rocks and bumps. Friend I was riding with left me in the proverbial and actual dust, so maybe 60 for him. During the descent, we passed this Subaru crawling down the road, like it was standing still. This was also the pre-suspension age, so I should score a few bonus points for that. Or stupidity points, depending on your scale.
Personal top speed in a car, about 100 mph. On a motorcycle, that be 136 mph on my Aprilia Falco - which it did effortlessly. Speed is all relative however. Hitting 60+ mph on a bicycle is much more impressive then twisting a throttle or pushing down a gas pedal.
Pro level racers cranking those long descents in the Tour and other races are showing some impressive skill - and risk. Amazing to watch though.
