Hard to tell, as there is a lot of variation between riders and rides.
For my daily commute it's about 14 MPH (22 KMH), but for races and racers it can be 25 MPH(40KMH) or more.
People on more upright bikes might not do more than 10 MPH(16 KMH)
depends 2 stroke of 4 stroke and racing bike or a trail bike
Average speed is 6km/3hr = 2km/hr = 2KPH.
Not particularly, 10 mph is below average sprinting speed. The record speed on a mountain bike is above 100mph.
20
Average speed = total distance / time taken = 90/3 = 30 mph
The answere would be 15.333
with average speed, 8-12 minutes approximately
40 miles is equal to 64.37 Kilo meters. Hence the speed of the bike can be found as speed=distance traveled by time. 64.37/2= 32.19 kph.
he ride a yellow bike that hasten speed
Depends! but if you got a good one then the average speed is 25-35mph.
a 10 speed racer is a dirt bike a 10 speed racer is a dirt bike
the top speed of a 150cc dirt bike can depend on a lot of things like if its a 2 stroke or a 4 stroke engine what kind of terrain your on and how much you way but the average is about 50-55mph
