A bicycle (or bike) is a two-wheeled human powered land vehicle that is propelled by pedals and steered with handlebars. It has a frame, a seat, and two wheels that are connected by a metal chain, which runs over cogs on both the pedals and the rear wheel. The rider, or cyclist, stands on top of the seat and pushes on the pedals with their feet to move the bicycle forward.

A skilled cyclist can balance the bicycle hands-free by leaning slightly left and right to keep the center of mass over the wheels to minimize the force arm of gravity. This is why it’s impossible for a bike to fly away or sink into the ground.

The frame gives the bicycle strength and sets the stage for how well all the other parts will function. The frame shape, material, and quality determines how well the bicycle rides and handles. There are many types of frames, and some have special features to enhance the cycling experience.

The handlebars connect to the stem that connects to the fork, which in turn connects to the head tube. There are three styles of handlebars: upright, which curve gently back toward the rider, for a natural grip and comfortable upright position; drop handlebars, which curve downward and allow riders to get into a more aerodynamic “crouched” position; and mountain, which have straight or curved bar ends that let riders hold them close to their bodies.

Cycling is a great way to stay in good health and have fun. It is easy and enjoyable to do, doesn’t require expensive equipment or a lot of space to store, and can be done at almost any intensity, from very low to very high. It increases muscle strength and stamina, and also improves cardiovascular endurance and aerobic fitness. People who cycle regularly are less likely to suffer from heart disease, diabetes, obesity, and some cancers.

Biking is an excellent way to reduce air pollution and traffic congestion. The noxious gases and particulates released by motor vehicles can harm people’s health and damage the environment. Removing cars from the roads and replacing them with bikes reduces the need for oil and gas, and makes our cities less congested and more pleasant to live in.

It’s easy to see why so many people love their bicycles! It’s a great way to have fun, explore your local area, and get some exercise. And it’s a great way to save time, since you can use your bike instead of taking the bus or driving a car!
