Mountain biking is the sport of riding bicycles off-road, often over rough terrain, using specially designed mountain bikes. Mountain bikes share similarities with other bikes, but incorporate features designed to enhance durability and performance in rough terrain.

Mountain biking can generally be broken down into multiple categories: cross country (XC), trail riding, all mountain, downhill, freeride, slopestyle, dirt jumping, and trials. The vast majority of mountain biking falls into the recreational XC,Trail Riding and Enduro categories.
