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 be performed almost anywhere 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 singletrack narrow trails that wind through forests, mountains, deserts, or fields.
