Bicycle

A bicycle is a two-wheeled vehicle powered by human effort, typically through pedaling. It consists of a frame, handlebars for steering, pedals connected to a chain to drive the rear wheel, and wheels with tires that help smooth the ride. Bicycles are eco-friendly transportation options offering exercise and mobility, used for commuting, recreation, and sport. They operate through basic mechanical principles, translating pedaling energy into motion, and can be adjusted for comfort and efficiency. Bicycles are versatile, cost-effective, and require minimal maintenance, making them a popular choice worldwide for sustainable travel and healthy activity.
