【The Invention of the Bicycle】
　　The history of human use of the wheel about 5000 years,and in 1839,Macmillan invented a mechanical bicycle.
　　The earliest bicycle was a wooden scooter-like contraption called a celerifere; it was invented about 1790 by Comte Mede de Sivrac of France.In 1816,Baron Karl von Drais de Sauerbrun,of Germany,invented a model with a steering bar attached to the front wheel,which he called a Draisienne.It has two wheels (of the same size),and the rider sat between the two wheels,but there were no pedals; to move,you had to propel the bicycle forward using your feet (a bit like a scooter).He exhibited his bicycle in Paris on April 6,1818.
　　Kirkpatrick MacMillan (1812-1878),a blacksmith from Dumfriesshire,Scotland,invented the first bicycle with foot pedals in the 1830 to 1840's,but he never patented it and his idea did not catch on locally.
　　A French father-and-son team of carriage-makers,Pierre and Ernest Michaux,invented an improved bicycle in the 1860's.Many early bicycles (called velocipedes,meaning "fast foot," or,more descriptively,"bone shakers") had huge front wheels —— it was thought that the bigger the wheel,the faster you could go.Early tires were wooden —— metal tires were an improvement,and solid rubber tires were added later.A chain with sprockets was added to the bicycle in the 1880's; this was called the "safety bicycle." Air-filled tires were also added in the 1880's.The derailleur gear system was added in the 1970's.
　　Nowadays,it's important for us to live the low-carbon life.So riding bicycle is the best choice for us to go around.It's not only benefit for our health and also cheaper than cars and the oil is not necessary for bicycles.The better thing is,it was so friendly to environment that it won't produce any polution.So let's go for a ride!
