Bicycles

Bicycles are human-powered vehicles typically consisting of two wheels, a frame, handlebars, pedals, and a seat. They are designed for transportation, recreation, or sport and are propelled by pedaling, which turns the rear wheel via a chain and gears. Bicycles can vary widely in design, purpose, and features, including types like road bikes, mountain bikes, and hybrids. They are an efficient mode of transport that offers health benefits, reduces environmental impact, and provides a means of exercise. Bicycles can also come equipped with various accessories such as lights, racks, and fenders for enhanced functionality.
