How fast is a pedal bike?

Answer 1

There are various records here depending on the terrain.

Downhill Recond: Eric Barone at 222km/h (138 mph)

Flat surface, motor-paced: Fred Rompelberg 268 km/h (167 mph)

Flat surface, unpaced: Sam Whittingham 133 km/h (83 mph)

Answer 2

There's no good single answer to that, as there are several different kinds of bikes and several different ways to ride. For something looking like a regular bike being ridden unassissted on flat ground fastest speed is about 60 km/h. Then there are faired bikes with the riders sitting in a streamlined shell, they are faster. Then there are bikes and bikers that are screened from the headwind by a vehicle travelling ahead of them which are even faster still.

Answer 3

That's a pretty pointless question. First of all a pedal bike w/o a rider doesn't go anywhere, so for similar bikes it's the rider who'll settle which is faster. Next item is that there are several different types of bikes and riding, and they all have different top speeds. You might as well ask "how fast is a car". There is one bike that's been clocked at over 70 mph, but that was a recumbent with a fairing. Looks more like a torpedo than a bike but still pedal powered. The speed record for DH bikes is higher, but that's with gravity supplying the power to move. A decently fit amateur rider can push an average of 25 MPH for hours on a reasonably flat course.
