Pocket bikes are bicycles that are built to look and feel like a small motorcycle. They are smaller than motorcycles, though most of them do have an engine. They are often used for racing.
Pocket bikes often go up to 50 mph, though the exact speed depends on the weight of the person riding it. The exact features of specific pocket bikes, also called mini-bikes, vary based on the manufacturer. Many of them include a two- or four-stroke engine with a centrifugal clutch. They are easy to ride because they are very light in weight, and they have front and rear disc brakes for safety.
