The real modern bicycle was born in 1874. 1874, Luo Song, an Englishman, ingeniously installed chains and sprockets on his bicycle, and used the rotation of the rear wheels to propel the car forward. But the front wheel is still big and the rear wheel is small, which looks uncoordinated and unstable.
1886, John K. stahly, a British mechanical engineer, designed a new bicycle style from the perspective of mechanics and kinematics. Bicycles are equipped with front forks and brakes, and the front and rear wheels are the same size to maintain balance. A diamond-shaped frame is made of steel pipe and rubber wheels are used for the first time. Stahly not only improved the structure of bicycles, but also transformed many machine tools for producing bicycle parts, which opened up broad prospects for the mass production and popularization of bicycles, so he was called "the father of bicycles" by later generations. The bicycle model designed by stahly is basically the same as the current bicycle.

The History of Bicycles in China
In the seventh year of Tongzhi in Qing Dynasty (1868), in June, 1 1, Shanghai shipped several bicycles from Europe for the first time. They are recreational vehicles for people to get on the bus and leave quietly.
In the 13th year of Tongzhi, Milla, a Frenchman, brought a rickshaw from Japan to Shanghai. This kind of rickshaw is called "Oriental rickshaw" and becomes a means of transportation because it is yellow. Subsequently, the repair, leasing and trading of rickshaws began in Shanghai.
After the 11th year of Guangxu reign in Qing Dynasty (1885), French foreign firms such as Jardine Matheson, Chanchen and Likang listed bicycles and spare parts as "hardware groceries" and imported them into Shanghai. By the end of 19, they had a broad market in Shanghai.
In the 23rd year of Guangxu, students who originally set up stalls to repair leather and rickshaws chose No.604 Nanjing Road (now Nanjing East Road) in Shanghai, and started Tongchang Car Shop, dealing in bicycles and spare parts.
In the 26th year of Guangxu, there were six or seven car shops in Shanghai, such as Huimin and Cao Shuntai, which sold rickshaws, carriages and bicycle spare parts for sale and repair.
In the 4th year of the Republic of China (19 15), there were nearly 20 bicycle shops in Shanghai. After the First World War, with the development of post and telecommunications, bicycles became the means of transportation for postmen, and the demand for bicycles surged. A number of bicycle shops have been opened in the urban area, forming a bicycle sales network centered on Laozha District (now Huangpu District).
Due to industrial characteristics and labor cost factors, the global bicycle manufacturing industry has shifted to countries and regions with industrial manufacturing advantages in recent 15 years, mainly China. At present, China has become the largest bicycle production base in the world, with more than 500 vehicle manufacturers and more than 700 parts manufacturers. The main bases of the world's top five manufacturers are all in China.
