There's really no telling, as there's a wide span between different kinds of bicycles and different kinds of riding.
On the flat, with a cross-country MTB, maybe 25-30 MPH in a sprint.
With a Down-Hill MTB, maybe 50+ MPH.
A mountain bike can typically reach speeds of 25-30 miles per hour on flat terrain, but can go faster downhill or with a strong rider.
If you pedal very fast then you may lose control
A mountain bike typically goes around 10-20 miles per hour when ridden on rough terrain.
A mountain bike can reach speeds of up to 40-50 miles per hour when ridden downhill on a steep slope.
it depends on how on how fast you petal and how fit you are
Not particularly, 10 mph is below average sprinting speed. The record speed on a mountain bike is above 100mph.
The maximum speed of a 21-speed mountain bike can vary depending on factors such as the rider's strength and terrain. On flat ground with a strong rider, a 21-speed mountain bike can reach speeds of up to 25-30 miles per hour.
As fast as a bike.
