How fast can different types of bikes typically go?
1) Mountain bikes with front AND rear suspension
2) Mountain bikes with front suspension
3) Road bikes with front suspension
4) Rigid frame road bikes
5) Single speed road bikes
6) Racing bikes
7) Single speed racing bikes

Of course, the speed will depend on the terrain and the skill/strength of the rider but I'm looking for average values and also if you know, the speed records for these types of bikes.
