The development history of bicycle, and some information and inventions involved in it! Thank you!
Questioner: It has been more than 2 years since the bicycle was invented. Today, as a means of transportation, exercise, cross-country travel, sports competitions and a small amount of goods transportation, bicycles have spread to every corner of the world. So, do we know the history of bicycle development?
express train-the earliest bicycle
One day in the summer of 1791, many men and women gathered on the lawn of Louis XVI's palace. Suddenly, there was a sound of "De De", accompanied by a loud sound of "De". In an instant, people saw a man named Conte de Chirac rushing through the middle of the croquet field. However, Chirac did not run like ordinary people, but sat on a strange "wooden horse" with wheels, and his feet pedaled on the ground with running movements. When Chirac reached the end of the lawn, he turned the "wooden horse" and ran back. People were shocked and attracted by Chirac's "rolling wooden horse", which was called "running fast", and the real bicycle history really began from now on.
Pedals-Feet start to leave the ground
One day in p>1863, Pierre Michaux, a Frenchman, rode out of his house on an early two-wheeled bicycle, and all the people in the rue Saint-Martin in Paris stared at him. Why? It turned out that Michaux's feet never touched the ground! Michaux is the first person to ride a bicycle without stepping on the ground with two pedals. At this time, many models of bicycles weighed 1 pounds.
Rubber-free tires-4 bicycles sold in a year
In p>1865, Michaux's carriage shop sold 4 rubber-free bicycles with pedals improved by him in a year. But at this time, the bicycle is still called "the car with broken bones", and its shock absorption function is much worse.
large and small wheels-finally reduced the weight
In p>1869, at the first bicycle show held in France, bicycles with large front wheels and small rear wheels appeared. In 1871, James Stari of Coventry, England, built the first bicycle named Ariel. This kind of car is very light, and Stari is also called "the father of bicycle industry". Bicycles with large and small wheels are the first kind of bicycles popular in major industrial countries in the world.
safe type-popular among women
In p>1879, H．J． Lawson of Britain developed a 3-pound, two-wheeled chain-driven bicycle. The wheels are small and light, so the cyclist will not turn over the handlebars even if he brakes suddenly. This kind of bicycle is welcomed by women, and any bicycle made according to this design idea is called "safe bicycle".
tricycle-for safety
the two rear wheels are larger, and the chain drives the rear wheels, which has a good balance effect and is conducive to pushing the whole car forward. In 189, the tricycle made by Peugeot Company in France could carry 11 pounds of goods, which made it have special commercial value.
pneumatic tires-the first important improvement of safe bicycles
In 1885, a pneumatic tire bicycle was successfully developed by Scottish john boyd Deng Lupu.
transmission-the key to the development of lightweight racing cars
the "Deux Vicesses" bicycle made in p>1888 was one of the early two-speed bicycles. At present, from the initial two-speed to 18-speed transmission.
With the popularity of light rickshaws, in a few years, fashionable contemporary racing cars may be seen as old-fashioned as safety bicycles and as grotesque as early large and small bicycles.

There are many sayings about the invention of bicycles.
① China is the first country to invent bicycles in the world. The ancestor of bicycle was a unicycle in China for more than 5 years BC. During the reign of Emperor Kangxi in Qing Dynasty (1662 ~ 1722), Huang Lvzhuang once invented bicycles. "Grand View of unofficial history in Qing Dynasty" has been published for eleven years: "A two-wheeled car made by Huang Lvzhuang is more than three feet long, which can seat one person without push-pull. When you walk, turn around with your arm around the shaft, and then you will walk as before, and you will walk eighty miles with your arm around the sun. " This is the earliest bicycle in the world.
② Bicycle was invented by western Europeans. In 179, the Frenchman Sifrak developed a wooden bicycle without handlebars, pedals and chains. The shape of the car is like a wooden horse with two wheels nailed to its feet, and the two wheels are fixed on a line. Because this bicycle has no driving device and steering device, and the seat cushion is low, Sifrak rides on the bicycle himself, with his feet on the ground, and pushes back hard to make the bicycle move forward in a straight line. In 1817, Baron von Delaisse invented a handlebar that can move freely, which made it easier for him to change his bicycle. In 1818, Delaisse applied for a patent in Britain. In 1839, K. Macmillan, a British worker, pioneered a pedal bicycle with a crankshaft mechanism to drive the rear wheels, so that people can leave their feet off the ground when riding a bicycle. One day in 1861, Michaux and his son, a Parisian carriage and stroller manufacturer, repaired the Delaisse bicycle. When they tried it on the ramp after repair, they found it difficult to put their feet on it, so they improved it and put a pedal crankshaft on the front wheel of the car, thus inventing the Michaux bicycle. Soon, this kind of bicycle began to be mass-produced. Around 187, the French horse master made a bicycle with a big driving wheel in front and a small driven wheel in the back, which worked well. After 189, Humber Company in Britain produced a bicycle with a chain drive and a rhombic bicycle. This type of bicycle has been in use ever since.
③ Bicycles were invented by Russians. One day in September 181, Artamonov, a Russian serf, rode his own wooden bicycle and traveled 2,5 kilometers to Moscow to present a gift to Tsar Alexander I. Bicycles made in Artamonov are similar to those made in France by Sifrak. When Alexander I saw the bicycle made in Artamonov, he immediately ordered the cancellation of his slave status.
ah, people and machines are so outstanding! "A senior Turkish official praised Stevens when he saw him get off his bicycle" Ordinary Man ". Humans have used wheels (or single wheels, or two wheels, or three wheels, or four wheels) for about five thousand years, but before 169, no one connected the two wheels to ride. A Frenchman named De West Flach straddled a two-wheeled car he called "Celeriffler" with his feet apart, and put one leg on one side to make it roll forward. The rolling of the wheels is limited, because he hasn't created a way to drive this machine. The drivable Dreyfus car was successfully developed by Karl von Dreyfus in 1817. It is a mechanical bicycle, which was invented by Macmillan in 1839. The rear wheel is driven by a crank connected to the pedal. With bicycles, human beings can travel on their own, and it is much faster than walking. However, not many people are interested in this idea. In 1861, a French hatter named brunell took his Dreyfus to the carriage craftsman Michaud to have it repaired. Ernest, Michaud's son, probably didn't know Macmillan's invention at all, so he suggested that if a crank-like the handle of a mill-was installed on the front wheel and it could be turned step by step, this machine would certainly be improved. In this way, he accidentally started the bicycle industry. In some early bicycles called "Velocipide", the pedals turned once, and the wheels turned once. Before the invention of the bicycle called "Penny Fassen", the front wheels became bigger and bigger. People properly call this kind of car "high bike". It runs fast, but it is not stable: if you want to brake, especially when you are going downhill, the cyclist may be thrown in front of the handlebar, and you will have to fall several times after riding a car for a day. However, people were not frightened. The sports club was established. In 1884, the brave Thomas Stevens rode, pushed and sometimes even carried a tall bicycle called "Ordinary Man" across the United States. Attempts to make the front wheel smaller, thus making the bicycle safer, were carried out intermittently, however, these attempts failed due to the limitation of the technological level at that time; Reliable bicycle chain is an important invention, without which it is impossible. In 1885, stahly invented a chain-driven bicycle, named "Safety Rover", thus ending the era of high bicycles. Bicycles quickly adopted chain transmission, but did not adopt his structural design. People have tried various methods to connect two wheels in an attempt to combine rigidity, controllability, mechanical efficiency and comfort. Driving soon became quite reliable and efficient. Dunlop reinvented pneumatic tires in 1888, which further developed bicycles. It seems impossible to have any fundamental changes in bicycles at present. In recent years, many people want to develop a better bicycle, but their efforts are fruitless.
nowadays, bicycles are like the tide, spreading all over the world and entering every household. But few people know that the bicycle was invented by a German ranger named Delaisse (1785-1851).
Delaisse used to be a forester. He had to walk from one forest to another every day. The hard work of walking for many years aroused his desire to invent a means of transportation. He thought: If people can sit on wheels, they will walk faster! In this way, Delaisse began to design and manufacture bicycles. He made a wheelbarrow with two wooden wheels, a saddle and a handlebar attached to the front wheel for control. People sit in the car and drive the wooden wheels with their feet. In this way, the world's first bicycle came out.
In 1817, when Delaisse traveled by bike for the first time, he was ridiculed all the way ... He was determined to answer this ridicule with facts. In a race, he rode for 4 hours, but the horse-drawn cart took 15 hours. Nevertheless, no manufacturer is willing to produce and sell this kind of bicycle.
In 1839, Macmillan, a native of Su Gelan, invented the pedal and put it on the front wheel of the bicycle, which greatly improved the bicycle technology. In the following decades, various bicycles have emerged, such as windsurfing bicycles, water treadmills, ice bicycles and five-wheeled bicycles, and bicycles have gradually become popular means of transportation. With the emergence of pneumatic tires and chains, the structure of bicycles is becoming more and more perfect.
Delaisse also invented meat grinder and typewriter, which can reduce labor intensity. At present, the trolley propelled by railway workers on the rails by manpower was also invented by Delaisse, so it is called "Delaisse".
