Mountain biking is a sport which consists of riding bicycles off-road, often over rough terrain, using specially adapted mountain bikes.
Mountain bikes share similarity with other bikes, but incorporate features designed to enhance durability and performance in rough terrain. Mountain biking can normally be broken down into multiple categories: cross country, trail riding, all mountain, downhill, free ride, street riding, dirt jumping and trials. This personage sport requires endurance, core strength and balance, bike handling skills and self-reliance. XC type mountain biking generally requires a lesser range of skills but a superior level of fitness than other types of mountain biking.
Advanced riders chase steep technical descents and, in the case of free riding, down hilling, and dirt jumping, aerial maneuvers off of specifically constructed jumps and ramps.
Mountain biking can be performed almost wherever from a back yard to a gravel road, but the majority of mountain bikers ride off-road trails, whether country back roads, fire roads, or single-track (narrow trails that wind from side to side forests, mountains, deserts, or fields). There are aspects of mountain biking that are more equivalent to trail running than regular bicycling. Because riders are often far from civilization, there is a strong ethic of self-reliance in the sport. Riders learn to repair their broken bikes or flat tires to avoid being stranded miles from help.
This reliance on continued existence skills accounts for the group dynamics of the sport. Club rides and other forms of group rides are common, particularly on longer treks. A amalgamation sport named mountain bike orienteering adds the skill of map direction-finding to mountain biking.
