BMX bike

A BMX bike is a bicycle used for cycle sport, specifically racing or stunt riding.

Though originally denoting a bicycle intended for BMX racing, the term "BMX bike" is now used as a generic term to encompass race bikes ('class' and 'cruiser') and those used for freestyle disciplines (street, vert, park, flatland), and dedicated dirt jumper bicycles.

Frames are made of various types of steel, aluminum, or carbon fiber.

[1] BMX race bikes extensively use aluminum or carbon fiber.

These bikes come with thick and fat tires to absorb shocks and for better jumping.
