Who first invented the bicycle?

On a rainy day, Sifrak, a Frenchman, was splashed with mud by a passing carriage when he was walking in the street. This splash made him suddenly think that the carriage was so wide that it should be cut in half and the four wheels should be turned into two wheels ... So in 1791, the first "wooden horse wheel" car was born. This car has two wooden wheels, front and back, with a beam in the middle, and a bench on it, like a toy. The new things that have just appeared are definitely not so perfect. This "wooden horse wheel" has neither a transmission chain nor a steering device, so it naturally needs improvement.

In 1818, a German woodsman named Delaisse had an occasional idea, and he also made a wooden cart, which looked similar to that of Sifrak, but he added a handlebar to the front wheel to control the direction, which could change the direction of progress. But when riding a bike, you still have to use two pedals to push the car forward. At that time, when Delaisse rode his "Little Horse" on the road to test, he was laughed at by many people. The emergence of new things will always be laughed at by traditional forces of one kind or another, but the inventor of human beings will never stop because of these ridicule. In 184, Macmillan, an English blacksmith, improved the pony cub invented by Delaisse. He installed a crank on the axle of the rear wheel, and then connected the crank with the front pedal with a connecting rod, and both the front and rear wheels were made of iron. The front wheel was big and the rear wheel was small. In this way, people's feet really leave the ground, from the alternate stepping of their feet to the rolling of the wheels. In 1842, Macmillan got on this car and ran 2 kilometers a day.

By 1861, Messaud and his son in France installed a rotatable pedal on the front wheel, and the saddle of the car was mounted on the front wheel. They dubbed the car a "bicycle" and it appeared in the Paris Expo in 1867, which opened the eyes of the audience.

From Sifrak to Renault, the bicycles they made are quite different from modern bicycles. The truly modern bicycles were born in 1874. Luo Song, an Englishman, put chains and sprockets on his bicycle in an ingenious way, and used the rotation of the rear wheel to propel the car forward. But it is still not coordinated and stable enough.

in p>1886, stahly, a British mechanical engineer, designed a new bicycle style from the perspective of mechanics and kinematics. The front fork and brake were installed, and the front and rear wheels were the same size to maintain balance. A diamond frame was made of steel pipes, and rubber wheels were used for the first time. Stahly not only improved the structure of bicycles, but also reformed many machine tools for producing bicycle parts, which opened up a broad road for the mass production and popularization of bicycles, so he was called "the father of bicycles" by later generations. The bicycle model he designed is basically the same as that of today's bicycles.

human wisdom is really ubiquitous. In 1888, Dunlop, an Irish veterinarian, was inspired by the treatment of flatulence in cattle. He glued a rubber hose for watering his garden into a round shape and put it on a bicycle, which was the beginning of pneumatic tires. Pneumatic tire is an epoch-making pioneering work in the history of bicycle development, which not only fundamentally changed the riding performance of bicycles, but also improved the use function of bicycles. From 1791 to 1888, the invention and improvement of bicycle, the ancestor of motorcycle, experienced the unremitting struggle of these inventors for nearly 1 years. We have to be moved by human inventions.
