Bicycle - a High Utility Vehicle Evolution of cycling began in 1818 with push bikes or hobby horses which were like a wooden frame and two wheels in line and the driver used to push with their feet when you're on the front wheel. In 1839 it was refined, like a crank drive mechanism has been added to the rear wheel.
A new design of the bicycle made his debut in the 1850s and 1860s when the French Pierre Michaux and Pierre Lallement placed pedals on an enlarged front wheel. It was made of wrought iron and wood with mounted wire spiked wheels with rubber tires on a tubular steel frame. But this designed faced problem of very high seat and the unequal distribution of weight.
Subsequently, these problems have been solved to some extent by reducing the diameter of the front wheel, adding gears to attain enough speed, setting the seat in the middle, etc., but it faces the major problem with front wheel, two pedals and steer were attached to it. Then JK Starley, JH Lawson and Shergold connected the pedals with the rear wheel with the transmission system to reduce the problem. These bikes have been given a name bicycle safety or security dwarf, as they had lower seats with equal distribution of weight.
the golden age of bicycles began in 1890, as new innovations in these bikes more comfortable. tire was an invention of Scotsman John Boyd Dunlop in 1888, then only freewheel was developed. Subsequently, the coastal brakes were invented in 1898. This period also marks the introduction of derailleur cable and hand-pull brakes. Soon he became famous worldwide because of its great utility in alsmost all areas. It was used in India to distribute milk in the house, used by factors for mail delivery, used by the military for troop movement, and it has also become a source of recreation.
With advent of technology and modern materials, various types of bicycles are launched on the market. There are a range of bikes utilities, road bikes, mountain bikes, BMX bikes and much more. You can select the type of bike according to its needs term of office, the number of riders, etc.
A rider mounts the bicycle by keeping it upright so that the center of gravity stays on its wheels. He leans while taking a turn by turning the handlebars with his hands. It uses the brakes to stop, as the brakes stopping force applied to the front wheels. It is the most energy efficient transportation, as it requires very little energy to mount a slow speed and transmits 99% of the energy of a rider to the wheel.
With the advent of technology and innovatios, the design of bicycles has remarkably changed. There are different models for men and women, races and walks ordinary freight carriers and the use of the circus. Each model has its own characteristics to meet the unique needs of the rider like gears for racing cyclists, cushioned stools short distance riders, disc brakes for mountain biking, etc.
The use of the bicycle has not only the man of the improvement of everyday life, but also helped improve the environment because cycling doesn `t polllution question. In addition, it has positive effects on one `s health. Manufacturing of bicycles has led to the deveopment other industries such as the composition of ball bearings, nuts, washers, etc., as many companies make frames of bicycles and buy other parts for other companies.
