Mountain biking is a sport of riding bicycles off-road, often over rough
terrain, usually using specially designed mountain bikes. Mountain bikes
share similarities with other bikes but incorporate features designed to
enhance durability and performance in rough terrain, such as air or
coil-sprung shocks used as suspension, larger and wider wheels and
tires, stronger frame materials, and mechanically or hydraulically
actuated disc brakes.
Mountain biking can generally be broken down into five distinct
categories: cross country, trail riding, all mountain (also referred to
as "Enduro"), downhill, and freeride.[1]
