Cycling as a sport has its origins in the mid-19th century in Europe, particularly in France and the United Kingdom. It initially gained popularity as a form of transportation and recreation before evolving into a competitive sport with the development of organized races and events. The invention of the modern bicycle with pedals and a chain in the 1860s played a significant role in the growth of cycling as a sport.
