The invention of the wheel is among the greatest discovery by the mankind and has proved to be a great boon. Ever since its invention man has tried to use it for numerous applications. When efforts were being made to develop a steam-run motor car capable of plying on the road, man was also engaged in designing a two wheeled cycle (bicycle).
The first bicycle was made by Baron Van Drais of Germany in 1817. He named this bicycle as ‘draisine’ after his name. It had two wheels connected by a wooden rod. A cyclist would rid it and push his legs against the ground to move forward. The front wheel was provided with handle to negotiate turns. This machine was so costly that people named it ‘dandy horse’. ln 1840, Macmillan made some improvements in this cycle. He attached paddles to the back wheel. In 1865, Lallement of France developed another type of cycle with paddles attached to the front wheel. People started calling it a ‘bone shaker’ because a rider of this cycle used to get big jerks.
It was realized at this stage that increasing the size of the front wheel would increase the speed of the cycle. For experimental trials, cycles with very large front and very small rear wheels were made. The diameter of the large wheel was about 1.5 meter while that of the small wheel was about 0.3 meter. A cyclist riding a bicycle of this type always had the risk of falling down. Afterwards, several improvements were made in the bicycles. Finally in 1885, the safe bicycle of today was developed. Both the wheels of this bicycle were of the same size and a seat was provided for the rider. It had paddles also. With the passage of time, this bicycle also underwent many improvements. Today you see that very beautiful and easily movable bicycles are being produced. The use of bicycles is now a very common feature of villages, towns and cities.
