What is a good top speed on a mountain bike w/semi-slick tires, and riding on a flat surfaced road, in mph?
is 42 kph a good top speed?
On the level? It's hard to get much above 20mph because of the gearing. Downhill when you don't have to pedal, I've been well over 40mph before I got scared :))
it depends on the person but i would assume that if you are going full on you could reach a speed of 25-30mph. but it also depends on how the bike is geared
