The history of bicycle development.

The history of bicycle development.

　　Industry profile,

　　Bicycle is a traditional industry, has a history of more than 100 years, due to environmental and traffic problems, the bicycle has once again become the countries of the world, especially developed countries people favorite traffic tools, fitness, bicycle industry in the world's centre of gravity is from traditional walking type vehicles to sports, mountain, casual, in the United States, Europe, Japan and other developed countries, the bike is a more common sports, fitness, leisure and entertainment products. There is a huge demand for bicycles around the world every year. According to statistics from CYCLEPRESS, Japan, the world's bicycle demand is kept at a level of 106 million, with annual turnover of about $5 billion.

　　history

　　Bicycle is one of the most successful human machines invented by man. It is a complex machine composed of many simple machines. During the kangxi reign of the qing dynasty, huang took the initiative to develop a bicycle. According to the history of the qing dynasty, "a two-wheeled cart with a long three feet and a long distance, can sit one person, without pushing the arm, and can do it." When you walk on the side of your arm, you will be able to walk on your arm. Thus, the bicycle he made, with one wheel on each side, and the rider on the other side of the axle, could move forward, which is the earliest recorded bicycle. It took about 100 years for the French to make a wooden bicycle in 1790.

　　Design a prototype

　　In 1790, there was a Frenchman named sivlak, who was particularly fond of thinking. One day he was walking down a street in Paris, because it had rained the previous day, and there was a lot of rain on the road. Suddenly, from behind a carriage is rolling in and the street is narrow, the carriage is very wide, the schiff, hide to hide to fortunately not knocked down by a car, or was spattered mud and rain. The others saw it, and felt sorry for him, and cursed with anger, and tried to call the carriage to stop. "Don't shout," he muttered. "stop Shouting and let them go." The carriage was far away, and he was still standing by the side of the road. He thought, why can't you change the structure of the carriage so narrow and so pedestrian? The cart should be cut in half, four wheels turning into two wheels... He wanted to go home and design. After trial and error, the first "Trojan horse" car was built in 1791. The earliest bicycles are made of wood, its structure is simple, neither drive, also have no steering device, cyclists on foot hard ground, change direction, and can only move the car when the car. Even so, when he rode the bike to the park, he was amazed and amazed.

　　To improve the

　　In 1816, in Germany, there was a man named drales, who went from the forest in the village to the other woods in the west of the village every day. He thought: if people are sitting in the car, go to stop, do what they want, is not very smart? DE les started making a wooden wheel that looked almost like the one he had built. However, a steering wheel was added to the front wheel to change direction. But when you ride a bike, you still have to use two feet to push the car forward. When dreyles rode out on his bicycle, he was laughed at by many people. Still, he loved his "cute little pony bike". A DE les when cycled around driving a carriage, the driver laughed at he said his car slowly, so he and the driver said: "your letter not letter I car faster than your carriage" and they two made a bet. The journey was from the village to the west of the village, and it turned out to be more than an hour faster than the driver.

　　In 1840 macmillan, an English blacksmith, got a rundown "cute little pony". He put a crank on the axle of the rear wheel and connected the crank to the front pedal with a connecting rod. The front and rear wheels were made of iron, the front wheel was large and the rear wheel was small. When the cyclist pedals, the car will move and run forward. They were caught by the police and fined. The crime was "brutal cycling". In 1861, in France, the michos, who were originally employed as carriage repairers, fitted the wheel with a rotating pedal. The saddle of the car is on the front wheel, so unless the technology is very good, you can't catch the car and fall off the car. They dubbed the two-wheeled vehicle a "bicycle" and exhibited it at the Paris exposition in 1867, which opened the eyes of the audience.

　　In 1869, Britain's Renault looked at the French bicycle and thought it was too heavy, and began to wonder how to make it lighter. He USES steel wire spokes to tighten the wheel as the wheel; At the same time, using the fine steel rod to make the frame, the front wheel of the car is larger, the rear wheel is smaller. The bike itself is reduced in weight. From the start of sifrak to Renault, the five types of bikes they make are quite different from modern ones.

　　Modern shape

　　The truly modern form of the bicycle was born in 1874. For a year in 1874, the Englishman, roson, put a chain and sprocket on his bicycle and drove it forward with the back wheels. But the front wheel is big, the rear wheel is small, it looks uncoordinated and unstable.

　　In the UK in 1886, and John k. starr, is a mechanical engineer, from mechanics, design a new style of bicycle kinematic point of view, for the bicycle mount the front fork and brakes, front and rear wheels of the same size, in order to keep balance, made the diamond frame, and steel tube also use rubber wheels for the first time. Stelios not only improved the structure of the bicycle, also changed a lot in the production of bicycle parts in machine tools, to a large number of production and application of bicycle has opened up broad prospects, so he was called the "father" of the bike. The bike model designed by starley is basically the same as today's bike.

　　In 1888, Ireland's veterinary Dunlop, get inspiration from healing cow stomach gas expansion, he spent in home garden watering rubber and glued into round, play enough gas, mounted on bicycle wheels, to ride a bike race, incredibly, aroused people's great interest. Pneumatic tyre is an epoch-making innovation in the history of bicycle development. It increases the elasticity of bicycle and does not vibrate due to uneven road surface. At the same time, it greatly improves the driving speed and increases the friction between the wheels and the road surface. In this way, the cycling performance is fundamentally changed and the function of bicycle is improved.

　　Also in 1888, John k. stafford of coventry, England, produced the first modern bicycle, the "safe" bicycle. The main feature is the diamond frame structure, which makes the body have higher rigidity and strength, the rear wheel is driven by the chain, and the direction is grasped directly through the front fork.

　　Various design

　　The world's first truly practical bikes appeared in the early 19th century. In 1817, German DE les invented the wooden two-wheeled bicycle in Paris, France. The bicycle became a popular means of transportation in Europe. In the 19th century some of the europeans also dreamed up some ideal bike maps.

　　In the early stages of the invention of bicycle [1], the larger the wheel, the faster it was thought to travel, and the two men rode a bicycle with a wheel almost as high as one.

　　In the invention of the bicycle phase, some people didn't take the bike before and after the two wheels design into place, but the two wheels made placed around, the appearance of this kind of bicycle is similar to a wheelchair.

　　In 2012, China had a double-powered exercise bike. While riding, the car can push the car to get the driving force and achieve the perfect combination of fitness and walking. Due to the role of the push-pull car, in the cycling, can effectively exercise the waist, abdomen, legs, chest, arms and other body muscles. It opened a new era in the history of bicycles.

　　Technology alliance

　　With the development of the society, the bicycle products of professional research and development and technology demand is higher and higher, in 2011, the domestic numerous well-known bicycle lithium trams corporate r&d or technical department head to communicate with each other to explore, think in the current situation, the industry we need unity and cooperation, learn each other, complement each other, enterprises and individuals can have a long-term healthy development, in everybody's urging, China bicycle technology alliance for potential was established, by industry experience more than eight years of China's many well-known bicycle lithium trams enterprises engaged in research and development or technical department head join together to create, through extensive contact industry outstanding professionals, strengthen technological exchanges and cooperation, reflect the value of each person within the enterprise and at the same time promote the benign development of the industry.

　　In Chinese history

　　For the first time in the seven years of tongzhi (1868), Shanghai was the first to transport several bicycles from Europe, and it was a recreational vehicle for the recreational activities of people riding on the bus and walking on tiptoes.

　　In the thirteenth year of the same rule, the Frenchman, mila, imported a rickshaw from Japan to enter Shanghai, which is called "dongyang car" because it is yellow and "rickshaw". Later, the construction of rickshaws in Shanghai was built, rented and sold.

　　After the eleventh year of qing emperor guangxu (1885), English merchant jardine matheson, German ShangChan minister, local foreign firm, such as li kang will bicycle and parts listed as "hardware grocery class" input in Shanghai, has broad market in Shanghai by the end of the 19th century.

　　It was originally set up to repair horse-drawn carriages and rickshaw, which was located at 604 nanjing road, nanjing road (now nanjing east road).

　　Guangxu 26 years, Shanghai has huimin, cao shuntai and other six - seven cars, sales rickshaw, carriage and bicycle parts, to sell and repair.

　　In the fourth year of the republic of China (1915), there were nearly 20 bicycle shops in Shanghai. After the first world war, post and telecommunications enterprise development, to a postman means of transportation, bicycle a surge in demand, the city and a new batch of bicycle shop, formed by the old gate area (now huangpu district) as the center of the bike sales network.

　　Due to the industrial characteristics and labor cost factors, the global bicycle manufacturing industry has shifted to countries and regions dominated by China in the past 15 years. At present, China has become the world's largest production base of bicycle, vehicle manufacturing, auto parts factory reached more than 500, more than 700, the world's top five manufacturers main base in China.
