I cracked the 80 km/h (50 m.p.h.) on an average 21 speed mountain bike (as of 1994) on Mount Ousley Road, the Superhighway into Wollongong, Australia. I was shooting past trucks and buses in the centre lane, which were only permitted to do half this speed on the steep mountain decent. Also overtaken trucks on other highways in the mountains surrounding Australia's largest city Sydney.
i remeber watching a show and they towed a guy on a racing bike(geared up ) upto about 50mph then he pedelled upto 125mph( 200k),i think the show or video was called on "on any sunday"
The gears on that thing are more excessive than that of an overdrive gear in a car resulting in low torque and pooor acceleration. It would be the funniest thing ever if you pedaled so hard that you farted then suffacated because you were sealed in a carbon fiber/kevlar box of doom in the baking nevada sun, sort of like your own little gas chamber. Yea I own a mountain bike and a road bike and my mountain bike has decent gear ratios and I can pedal up to 45 mph down hill with a tail wind.
Higher than that, Brian. My top speed on my Bianchi is 47.4, and I know people who've gotten into the upper 50s. Some of my friends who ride recumbents, trikes, and tandems have hit 60.
