A bicycle is basically a human-powered, pedal-driven, single-track vehicle also simply called as a cycle or bike. It has two wheels attached one behind the other to a frame. A bicycle rider is named as a cyclist or bicyclist.
Bicycles were first introduced in Europe in the late 19th century and by the start of the early 21st century, greater than 1 billion bicycles were manufactured worldwide. These numbers have far exceeded the total number of cars. This number includes both the total and also the cycles ranked by the number of individual models produced. Today due to increasing pollution, riding cycles is greatly encouraged and appreciated in India and all over the world. This has increased the number of cycle manufacturers in India and cycle distributors in India too.
Bicycles have undergone continuous improvement since its inception. Since the making of the first chain-driven model around the year 1885, there has only been a slight evolution of the structural configuration of a typical upright or safety bicycle. But a lot of details have been improvised, especially since the inception of modern materials and computer-aided design. These have encouraged an increase in specialized designs for various types of cycling. This is now widely utilized by many cycle manufacturers in India as well. This has led to an increase in the number of specialized bicycles, bicycle safety, and riding comfort.
A bicycle will stay upright while moving ahead by being steered in order to maintain the center of mass on the wheels itself.
The aggregate center of mass of a bicycle and its rider must lean into a turn to successfully navigate it. This is induced by countersteering that can be performed by the rider twisting the handlebars directly using hands or indirectly by leaning the bicycle.
Bicycles could further be categorized in many different ways. These various types of bicycles are easily available with a cycle supplier in India or a cycle distributor in India and worldwide. Its functionality differs as per the number of riders, general built, gearing or by ways of propulsion. The more general types are mountain bicycles, racing bicycles, utility bicycles, touring bicycles, hybrid bicycles and cruiser bicycles.
Cycles are the primary means of transportation in a lot of regions. They also serve as a popular form of recreation and have also been modified to use as general fitness, children's toys, military, police applications, courier delivery, bicycle racing and stunts.
Today, bicycles are made easily available in the market by cycle suppliers in India. The invention of a bicycle has had a huge effect on society in terms of culture and modern industrial methods. Many components that played a key role in the making of various automobiles were gradually introduced for use in the bicycle. These elements include ball bearings and pneumatic tires along with chain-driven sprockets and tension-spoked wheels.
A bicycle is highly efficient in both biological and mechanical terms. It is a highly effective and efficient human-powered method of transportation in terms of energy. A person has to expend in order to travel a given distance. If considered from a mechanical point of view, up to 99% of the energy used by the rider into using the pedals is transmitted to the wheels. Although, the use of gearing mechanisms has the ability of reducing this by 10–15%. If considered in terms of the ratio of cargo weight, a bicycle possesses the capability of carrying the total weight. A cycle is thus an extraordinarily efficient means of cargo and other transportation in general.
