A bicycle, also called a pedal cycle, bike, push-bike or cycle, is a human-powered or motor-powered assisted, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.

Bicycles are one of the most popular and efficient modes of transportation in the world. They are human-powered vehicles that consist of two wheels, a frame, pedals, handlebars, and a saddle. Bicycles provide a cost-effective, eco-friendly, and healthy way to commute, exercise, and explore the outdoors.

Road Bicycles: Designed for speed and efficiency on paved roads, road bicycles have lightweight frames, thin tires, and drop handlebars. They are commonly used for racing, long-distance rides, and recreational cycling. Mountain Bicycles: Built to tackle rough terrains and off-road trails, mountain bicycles have sturdy frames, wide knobby tires, and front or full suspension. They are ideal for off-road adventures, trail riding, and mountain biking. Hybrid Bicycles: Combining features of road and mountain bicycles, hybrid bikes offer a versatile option for both city commuting and light off-road trails. They have a comfortable upright riding position, medium-width tires, and often come with accessories like fenders and racks.
