The history of
the bicycle is a story of gradual evolution, beginning with the
"running machine" invented by Karl von Drais in 1817. This early
two-wheeled vehicle, also known as the draisine, lacked pedals and was
propelled by the rider's feet pushing off the ground. Over time,
innovations like pedals, the chain drive, and pneumatic tires transformed the
basic design into the modern bicycle we know today.
Further
innovations throughout the 20th and 21st centuries, including advancements in
materials, gears, brakes, and electric assistance, have led to the diverse
range of bicycles available today. The bicycle has evolved from a novelty
item for the wealthy to a widely used and cherished mode of transportation,
recreation, and sport.
There are several categories of bicycle racing including road bicycle racing, cyclo-cross, mountain bike racing, track cycling, BMX, and cycle speedway. Non-racing cycling sports include artistic cycling, cycle polo, freestyle BMX, mountain bike trials, hardcourt bike polo and cycle ball. The Union Cycliste Internationale (UCI) is the world governing body for cycling and international competitive cycling events. The International Human Powered Vehicle Association is the governing body for human-powered vehicles that imposes far fewer restrictions on their design than does the UCI. The Ultramarathons Cycling Association is the governing body for many ultra-distance cycling races.
