Mountain biking is a 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, trail riding, all mountain (also referred to as "Enduro"), downhill, freeride and dirt jumping. However, the majority of mountain biking falls into the categories of Trail and Cross Country riding styles.

Mountain bikers ride on off-road trails such as singletrek, back-country roads, fire roads, and often venture to ski resorts that stay open in the summer for such activities. Because riders are often far from civilization, there is a strong ethic of self-reliance in the sport. Riders learn to repair broken bikes and flat tires to avoid being stranded. Many riders carry a backpack, including water, food, tools for trailside repairs, and a first aid kit in case of injury. Group rides are common, especially on longer treks. Mountain bike orienteering adds the skill of map navigation to mountain biking.
