The handlebars connect to the stem that connects to the fork that connects to the front wheel, and the whole assembly connects to the bike and rotates about the steering axis via the headset bearings. Different gears and ranges of gears are appropriate for different people and styles of cycling. These are toothed and work much the same as a chain—popular with commuters and long distance cyclists they require little maintenance.

Off-road tires are usually between 1.5 and 2.5 inches (38 and 64 mm) wide, and have treads for gripping in muddy conditions or metal studs for ice. Saddles also vary with rider preference, from the cushioned ones favored by short-distance riders to narrower saddles which allow more room for leg swings. A higher gear allows a cyclist to make fewer pedal turns to maintain a given speed, but with more effort per turn of the pedals. They cannot be shifted across a cassette of sprockets, and are used either as single speed or with a hub gear. A dérailleur system normally has two dérailleurs, or mechs, one at the front to select the chainring and another at the back to select the sprocket. Recent versions use bamboo for the primary frame with glued metal connections and parts, priced as exotic models.
This steering is usually provided by the rider, but under certain conditions, may be provided by the bicycle itself. Military uses of bicycles include communications, reconnaissance, troop movement, supply of provisions, and patrol, such as in bicycle infantries. Bicycles are used for transportation, bicycle commuting, and utility cycling. More than 1 billion bicycles have been manufactured worldwide as of the early 21st century. Dérailleur gears and hand-operated Bowden cable-pull brakes were also developed during these years, but were only slowly adopted by casual riders.
- Early in its development, as with automobiles, there were restrictions on the operation of bicycles.

The "dandy horse", also called Draisienne or Laufmaschine ("running machine"), was the first human means of transport to use only two wheels in tandem and was invented by the German Baron Karl von Drais. The design of the bicycle was an advance on the velocipede, although the words were used with some degree of overlap for a time. The word bicycle first appeared in English print in The Daily News in 1868, to describe "Bysicles and trysicles" on the "Champs Elysées and Bois de Boulogne".

Training wheels are sometimes used when learning to ride, but a dedicated balance bike teaches independent riding more effectively. Front-mounted baskets, front or rear luggage carriers or racks, and panniers mounted above either or both wheels can be used to carry equipment or cargo. Bicycle suspension refers to the system or systems used to suspend the rider and all or part of the bicycle.

Some US companies, notably in the tech sector, are developing both innovative cycle designs and cycle-friendliness in the workplace. In Copenhagen, a cyclists' organization runs a Cycling Embassy that promotes biking for commuting and sightseeing. There are also cycling-specific multi-tools that combine many of these implements into a single compact device. Some brands of tires are much more puncture-resistant than others, often incorporating one or more layers of Kevlar; the downside of such tires is that they may be heavier and more difficult to fit and remove. A patch kit may be employed to fix the puncture or the tube can be replaced, though the latter solution comes at a greater cost and waste of material. Over the longer term, tires do wear out, after 2,000 to 5,000 miles (3,200 to 8,000 km); a rash of punctures is often the most visible sign of a worn tire.

The front triangle consists of the head tube, top tube, down tube, and seat tube. Drag can also be reduced by covering the bicycle with an aerodynamic fairing. Drag can be reduced by seating the rider in a more aerodynamically streamlined position. A human traveling on a bicycle at low to medium speeds of around 16–24 km/h (10–15 mph) uses only the power required to walk. The bicycle is the most efficient human-powered means of transportation in terms of energy a person must expend to travel a given distance. The bicycle is extraordinarily efficient in both biological and mechanical terms.

In built-up cities around the world, urban planning uses cycling infrastructure like bikeways to reduce traffic congestion and air pollution. The bicycle has had a considerable effect on human society, in both the cultural and industrial realms. There are specialized bicycle tools for use both in the shop and at the roadside. The chain cycling classes jacksonville fl and the brake blocks are the components which wear out most quickly, so these need to be checked from time to time, typically every 500 miles (800 km) or so.
