BICYCLE
A bicycle is a human-powered vehicle with two wheels. The first bicycles, called “hobby horses”, were built about 200 years ago. The rider moved along by pushing his or her feet against the ground. The first pedal-powered bicycle was made by Scottish blacksmith Kirkpatrick Macmillan in 1839. In 1861 in Paris, Pierre Michaux built a bicycle on which the pedals turned the front wheels. It was known as the “boneshaker” and was the first popular bicycle. The modern bicycle, with a diamond-shaped frame and chain-driven back wheel, was designed in 1885 by Englishman John Starley.
MOTORCYCLES
Early motorcycles were simply bicycles with a small steam engine attached, but they were not practical machines. The first modern-style motorcycles, with a metal frame, two air-filled tyres and a lightweight petrol engine, appeared around 1900. Modern motorcycles have similar features to cars, but have much greater acceleration.
