Kerékpárok

Kerékpárok, often referred to as bicycles, are human-powered vehicles with two wheels attached to a frame. They are propelled by the rider pushing pedals, which turn a crankset, which in turn drives the rear wheel via a chain. The rider steers the front wheel using handlebars. This fundamental design has remained largely consistent for over a century, though numerous innovations have refined their performance, comfort, and specialized applications.

The history of the bicycle traces back to early 19th-century inventions like the velocipede, which lacked pedals. The addition of pedals to the front wheel, followed by the development of the chain-driven rear wheel and the safety bicycle design, marked significant advancements. Today, bicycles come in a vast array of types, including road bikes for speed on paved surfaces, mountain bikes designed for off-road trails, hybrid bikes combining features of both, and city bikes for urban commuting. Electric bikes, or e-bikes, incorporate an electric motor to assist the rider, making cycling more accessible and less physically demanding. Bicycles are used for recreation, sport, transportation, and exercise globally, promoting a sustainable and healthy lifestyle.
