Different gears and ranges of gears are appropriate for different people and styles of cycling. Multi-speed bicycles allow gear selection to suit the circumstances: a cyclist could use a high gear when cycling downhill, a medium gear when cycling on a flat road, and a low gear when cycling uphill. In a lower gear every turn of the pedals leads to fewer rotations of the rear wheel. This allows the energy required to move the same distance to be distributed over more pedal turns, reducing fatigue when riding uphill, with a heavy load, or against strong winds. 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. pedal cycle". Oxford English Dictionary (Onlineed.).

A good heavy-duty bike cover will protect your frame from rain, dust and the elements from causing parts of your bike to rust. Waterproof bike covers are a must have if you are plan on storing your bike in the garden. Indoor bike covers offer protection for your bike while it is stored under cover. Oxford makes both outdoor and indoor bike covers. Other words for bicycle include "bike", [13] "pushbike", [14] "pedal cycle", [15] or "cycle".

Until recently, bicycles have been a staple of everyday life throughout Asian countries. They are the most frequently used method of transport for commuting to work, school, shopping, and life in general. In Europe, bicycles are commonly used. [85] They also offer a degree of exercise to keep individuals healthy. [86] In addition, the carbon dioxide generated in the production and transportation of the food required by the bicyclist, per mile traveled, is less than 1⁄ 10 that generated by energy efficient motorcars. [56] Bicycle poverty reduction is the concept that access to bicycles and the transportation infrastructure to support them can dramatically reduce poverty. [87] [88] [89] [90] This has been demonstrated in various pilot projects in South Asia and Africa. [91] [92] [93] Experiments done in Africa ( Uganda and Tanzania) and Sri Lanka on hundreds of households have shown that a bicycle can increase the income of a poor family by as much as 35%.

Bicycles are used for transportation, bicycle commuting, and utility cycling. [44] They are also used professionally by mail carriers, paramedics, police, messengers, and general delivery services. Military uses of bicycles include communications, reconnaissance, troop movement, supply of provisions, and patrol, such as in bicycle infantries. [45] The International Organization for Standardization (ISO) has a special technical committee for cycles, TC149, that has the scope of "Standardization in the field of cycles, their components and accessories with particular reference to terminology, testing methods and requirements for performance and safety, and interchangeability".

Kits often also include a wax crayon to mark the puncture location. The combined center of mass of a bicycle and its rider must lean into a turn to successfully navigate it. This lean is induced by a method known as countersteering, which can be performed by the rider turning the handlebars directly with the hands [49] or indirectly by leaning the bicycle.

Bicycles were introduced in the 19th century in Europe. By the early 21st century there were more than 1billion. [1] [2] [3] These numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. [4] [5] [6] They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, bicycle racing, and bicycle stunts.
