Cycling involves riding bicycles, unicycles, tricycles, quadricycles and other similar human powered vehicles (HPVs).
Introduction
As a sport, cycling is governed internationally by the Union Cycliste Internationale in Switzerland (for upright bicycles) and by the International Human Powered Vehicle Association (for other HPVs, or human-powered vehicles). Cycling for transport and touring is promoted on a European level by the European Cyclists' Federation, with associated members from Great Britain, Japan and elsewhere. Regular conferences on cycling for transport are held under the auspices of Velo City; global conferences are coordinated by Velo Mondial .
Equipment
-
In many countries, the most commonly used vehicle for road transport is a utility bicycle. These have frames with so-called relaxed geometry, protecting the rider from shocks from the road, and easing low speeds steering. Road bikes tend to have a more upright shape and a shorter wheelbase, which make the bike more mobile but harder to ride slowly. The design, coupled with low or dropped handlebars, requires the rider to bend forward more, which reduces air resistance at high speed.
The price of a new bicycle can range from US$50 to more than US$20,000, depending on quality, type and weight (the most exotic road bicycles can weigh as little as 3.2kg (7 lb)) ). Being measured for a bike and taking it for a test ride are recommended before buying.
The drivetrain components of the bike should also be considered. A middle grade dérailleur is sufficient for a beginner, although many utility bikes come equipped with hub gears. If the rider plans a significant amount of hillclimbing, a triple-crank (three chainrings) front gear system may be preferred. Otherwise, the relatively lighter and less expensive two chainrings may be better.
Many road bikes include clipless pedals to which special shoes attach via a cleat, permitting the rider to pull on the pedals as well as push. Other possible accessories for the bicycle include locks, mudguards (UK)/fenders (US), luggage carriers and pannier bags, water bottles and bottle cages.
For basic maintenance and repairs, cyclists can choose to carry a pump, a spare inner tube, a CO2 cartridge, a puncture repair kit and tyre levers. Cycling can be more efficient and comfortable with special shoes, gloves, and shorts. In wet weather, riding can be more tolerable with waterproof clothes, such as cape, jacket, trousers and overshoes.
