How fast does a racing bike go?

Answer 1

Too many variables.

- what kind of shape you are in.

- distance

- wind direction

- weather

- riding solo or in a group

- fitness of the riders you are with

- etc, etc

- Elite group rides (amature) 30-50 miles. avg about 23-26 mph

- Decents on mountains, pro riders can get up 70 mph

- Pro races? depends on race/type of race.

- Usually one classics such as Paris-Roubaix avg speed is around 26 mph

for approx 257 km race distance. (about 6 hours in the saddle)

You can have the fastest/lightest bike in the world, but if you don't have the engine (legs) to ride it, and insane tolerance for pain for hours on end, no bike is fast.

Answer 2

There's really no short answer, as it depends on what kind of race bike it is, and how/where it is ridden. (crap answer because it doesn't help)

Typically, Tour de France riders will average 40-45km/hr depending on whether they are getting the wind broken ahead of them by other riders. This would be on a longer leg. On a short time trial leg of 50km, they might average 55km/hr.

A fit recreational rider can average 30km/hr on a long trip and sprint up to about 65km/hr on a flat roadway with no wind.

Downhill rides have been known to top 110 km/hr.

Answer 3

In the sprints, they can hit about 60 KMH/40 MPH for a few seconds. On long descents, they can reach 50+ MPH/80+ KMH.
