Types of bicycle

Bicycles can be categorized in different ways: e.g. by function, by number of riders, by general construction, by gearing or by means of propulsion. The most common types are:

Utility bicycles are designed for commuting, shopping and running errands. They employ middle or heavy weight frames and tires, internal hub gearing, and a variety of helpful accessories. The riding position is usually upright.

Mountain bicycles are designed for off-road cycling, and include other sub-types of off-road bicycles such as Cross Country (i.e."XC"), Downhill , and to a lesser extent Freeride bicycles. All mountain bicycles feature sturdy, highly durable frames and wheels, wide-gauge treaded tires, and cross-wise handlebars to help the rider resist sudden jolts. Some mountain bicycles feature various types of suspension systems (e.g. coiled spring, air or gas shock), and hydraulic or mechanical disc brakes. Mountain bicycle gearing is very wide-ranging, from very low ratios to high ratios, typically with 21 to 30 gears.

Racing bicycles are designed for speed, and include road, time trial, and track bicycles. They have lightweight frames and components with minimal accessories, dropped handlebars to allow for an aerodynamic riding position, narrow high-pressure tires for minimal rolling resistance and multiple gears. Racing bicycles have a relatively narrow gear range, and typically varies from medium to very high ratios, distributed across 18, 20, 27 or 30 gears. The more closely spaced gear ratios allow racers to choose a gear which will enable them to ride at their optimum pedaling cadence for maximum efficiency.

Touring bicycles are designed for bicycle touring and long journeys. They are durable and comfortable, capable of transporting baggage, and may feature any type of gearing system.

Cruiser bicycles feature balloon tires, curvy "cantilever" frames, upright riding position, and padded saddles. They are popular recreation bikes for those who value style and durability over performance, especially in resort areas. The many elaborate and fanciful cruiser designs of the 1930s-1950s have become a focus for bicyle collectors.

tandems or twins have two riders, one on the front and one on the back.

folding bicycles can be quickly folded for easy carrying, for example on public transport.

unicycles are not proper bicycles, as they have only one wheel.
