A bicycle is a human-powered, two-wheeled vehicle designed for transportation, recreation, and sport. It consists of a frame, wheels, pedals, handlebars, and a seat, allowing riders to move efficiently with minimal effort. Bicycles come in various types, including road bikes, mountain bikes, and hybrid bikes, each suited for different terrains and purposes. Cycling provides numerous benefits, such as improved cardiovascular health, reduced environmental impact, and cost-effective travel. Whether used for commuting, exercise, or leisure, bicycles offer a convenient and eco-friendly alternative to motorized transport. Many cities promote cycling by establishing bike lanes and sharing programs, encouraging sustainable mobility. From children learning to ride to competitive athletes, bicycles remain a popular choice for people of all ages, fostering fitness and independence.
