What Is Bicycle? The Complete Definition

A bicycle, commonly known as a bike, is a steerable, two-wheeled vehicle that is propelled by the rider’s feet. The front wheel of a normal bicycle is held in a rotating fork, and the wheels are positioned in line in a metal frame. The rider steers by swaying and turning handlebars that are fastened to the fork while seated on a saddle.

Pedals connected to cranks and a chain wheel are turned by the foot. A chain loop that connects the chain wheel to a sprocket on the back wheel transfers power. Bikes may be ridden at speeds of 16–24 km/h (10–15 mph), which is around four–five times faster than walking. Riding is simple to learn.

The bicycle is now the most effective way to turn human energy into movement. For transportation, leisure, and sports, bicycles are frequently used. Bicycles are crucial for getting people and things around in places where there aren’t many cars. Bicycles outsell cars three to one and are produced in equal numbers around the world.

Bicycles for commuting and shopping are strongly promoted in the Netherlands, Denmark, and Japan. In the United States, bike lanes have been built in numerous locations, and the government promotes bicycles as an alternative to automobiles.

Bicycling, often known as biking or cycling, is the riding of a bicycle for recreational purposes such as touring, exercise, and personal transportation.

Even though tricycles and unicycles have three wheels or one wheel instead of two, they are frequently referred to be bikes in informal contexts.
