Bicycle is one of the best tools for sports and leisure activities. Kinematics experts believe that cycling, like running, walking and swimming, can exercise the endurance of internal organs and improve the heart and lung function. Because riding a bicycle is a heterolateral dominant movement, the alternating pedaling of two legs can also make the brain functions of the left and right sides develop in a balanced and coordinated manner, thus improving the agility of the nervous system. It is understood that there are 20 million people riding bicycles to exercise in the United States today; In Europe, cycling "one-day tour" has also become one of the most fashionable sports.

James Finley Scott, a student at the University of California in the United States, was the first person to convert an ordinary bicycle into a mountain bike. After that, cross-country sports gradually became popular in Europe and America, and formed competitions. The International Cycling Union recognized this sport in 1990 and held the World Cup for the first time in 1991.
