The more common types include utility bicycles, mountain bicycles, racing bicycles, touring bicycles, hybrid bicycles, cruiser bicycles, and BMX bikes.
Road bicycles are designed to be ridden fast on smooth pavement. They have smooth, skinny tires and "drop" handlebars, and can be used for on-road racing. They are usually lighter than other types of bicycles. They can be ridden on paved trails, but most people find them uncomfortable and unstable on unpaved trails. Most road bikes are not capable of carrying heavy loads.
Cyclocross bicycles are a special type of road bike designed to be ridden on mixed surfaces (combination of pavement, unpaved trails, gravel, grass).
Touring bicycles are another special type of road bike. They are designed to be ridden on pavement, but are more durable for use on self-supported long-distance riding.
Mountain Bicycles are design for riding rough off-road trails. They have flat or upright handlebars, and a very low gear range for pedaling up steep trails. Most mountain bikes have some type of shock absorbers or suspension.
BMX Bikes are popular with kids because of their small size, but they are used by adults and kids alike for various styles of trick and stunt riding.
Mudguards, or fenders, protect the cyclist and moving parts from spray when riding through wet areas and chainguards protect clothes from oil on the chain. Kick stands keep bicycles upright when parked, and bike locks deter theft. Front-mounted baskets, Luggage carriers, and panniers mounted above either or both wheels can be used to carry equipment or cargo. Parents sometimes add rear-mounted child seats, an auxiliary saddle fitted to the crossbar, or both to transport children.
Standards, also called naked bikes or roadsters, are versatile, general purpose street motorcycles. They are recognized primarily by their upright riding position, partway between the reclining rider posture of the cruisers and the forward leaning sport bikes.
Scooter engine sizes range smaller than motorcycles, 50–850 cc (3.1–51.9 cu in), and have all-enclosing bodywork that makes them cleaner and quieter than motorcycles, as well as having more built-in storage space.
There are three major types of motorcycle: street, off-road, and dual purpose. Within these types, there are many sub-types of motorcycles for different purposes. Street bikes include cruisers, sportbikes, scooters and mopeds, and many other types.
