| Evolution of bicycle commenced in 1818 with push | | | | postman for mail delivery, used by military for |
| bikes or hobby horses which were like a wooden | | | | troup movement, and it also became a source of |
| frame supported by two in-line wheels and the | | | | recreation. With an advent of technology and |
| rider used to push it with his feet while navigating | | | | modern materials, various types of bicycles are |
| the front wheel. Then in 1839 it was refined, as a | | | | launched in the market. There is a range of utility |
| mechanical crank drive was added to the rear | | | | bicycles, racing bicycles, mountain bicycles, BMX |
| wheel. A new design of bicycle marked its | | | | bicycles and many more. One can select the type |
| beginning in 1850s and 1860s when Frenchmen | | | | of bicycle according to his requirement in terme |
| Pierre Michaux and Pierre Lallement placed pedals | | | | of functions, number of riders, etc. A rider rides |
| on an enlarged front wheel. It was made of | | | | the bicycle by keeping it upright so that the |
| wrought iron and wood with mounted wire spiked | | | | centre of gravity remain on its wheels. He leans |
| wheels with solid rubber tires on a tubular steel | | | | while taking a turn by turning the handlebars with |
| frame. But this designed faced problem of very | | | | his hands. He uses brakes in order to stop, as the |
| high seat and uneven distribution of weight. | | | | brakes applies stopping force to the front wheels. |
| Subsequently, these problems were solved to | | | | It is the most energy-efficient means of |
| some extent by reducing the front wheel | | | | transportation, as it requires very low energy to |
| diameter, adding gears to attain enough speed, | | | | ride in a slow speed and transmits 99% of |
| setting the seat in the middle, etc. But it faced | | | | energy of a rider to the wheels. With an influx of |
| major problem with the front wheel, as both | | | | technology and innovatios, the designing of |
| pedal and steer were attached to it. Then J.K. | | | | bicycles has remarkably changed. There are |
| Starley, J.H. Lawson and Shergold connected the | | | | different models for men and women, racing and |
| pedals with the back wheel with chain drive | | | | ordinary rides, cargo carriers and circus use. Each |
| system to reduce the problem. Those bicycles | | | | model has its own unique features in order to |
| were given a name of safety bicycles or dwarf | | | | meet the exclusive requirements of the rider like |
| safeties, as they had lower seats with equal | | | | gears for racing riders, cushioned saddles for |
| distribution of weight. Golden age of bicycles | | | | short distance riders, disc brakes for off-road |
| began in 1890s, since new innovations made these | | | | riders, etc. The use of bicycle has not only |
| bicycles more comfortable. Pneumatic tire was an | | | | improved man`s day to day life, but also |
| invention of Scotsman John Boyd Dunlop in 1888 | | | | contributed for better environment because |
| and then only freewheel was developed. | | | | cycling doesn`t cause polllution. Moreover, it has |
| Subsequently, coastal brakes were invented in | | | | positive effects on one`s health. Manufacturing of |
| 1898. This period also marked the introduction of | | | | bicycles has led to the deveopment of other |
| derailleur gears and hand operated cable-pull | | | | industries also like composition of ball bearings, |
| brakes. Soon it became world wide famous due | | | | sprockets, washers, etc., as many companies |
| to its high utility in alsmost every field. It was | | | | make frames of bicycles and buy other parts |
