In 1936, Japanese retired military officer and chaebol Kojima Kazusaburo drew lines and stakes on more than 200 acres of land near the old gate of Zhougong Temple in Xiaosunzhuang, the Fourth District of Tianjin. Four or five factories were equipped with more than a hundred old machines made in Japan, more than 200 workers were recruited, and the brand "Changhe Factory" (the earliest predecessor of Tianjin Bicycle Factory) was hung. Produces bicycle frames, rims, front forks, cranks, wheel discs, mud plates, three sets of axles and other main bicycle parts, plus some parts shipped from Japan, to assemble a 26-inch dark green bicycle, named "Iron Anchor" " brand, with a monthly output of 900 bicycles, this is also the earliest and largest bicycle factory in the country. W_aO,u After the liberation of Tianjin in January 1949, the Industrial Takeover Office of the Tianjin Municipal Military Control Commission sent people to take over the factory. It was tentatively named "Military Control Tianjin Machinery/Second Branch Factory" and was directly under the leadership of the Tianjin Municipal Military Control Commission. At the end of January, With support from many parties, the factory has fully resumed operations and officially started producing bicycles in February, and allocated 130,000 kilograms of millet as production funds. By the founding of New China on October 1, 1949, the factory was officially named "Tianjin Bicycle Factory". vv In April 1950, Tianjin Bicycle Factory launched the activity of "Building a New Generation of Strong, Durable, Beautiful and Light Bikes in China". More than 20 comrades workers voluntarily formed a trial production team. They dissected and analyzed the bicycles of Philips of the Netherlands and Japan. Horii, British Fengtou and other famous brand cars from various countries have taken their strengths and avoided their weaknesses and made reasonable improvements. They borrowed drawing tools and used wooden boards as drawing boards. They carefully designed and repeatedly screened, and integrated hundreds of suggestions from the workers. Develop a plan to build a new car. After repeated trials and improvements, major changes were made to the processing technology and tooling equipment. For example, the frame structure was improved, the length of the top tube was changed to 640 mm, the third and bottom bracket joints were changed to large furnace brazing, the handlebar size was widened, and the heat treatment carburizing formula was improved. In order to solve the material problem of the new car, the workers used a calender to roll the waste oil barrels into specification materials and transformed the old molds. After improving the production process, on July 5 of the same year, China produced the first bicycle designed and manufactured by itself and assembled entirely with domestic parts. Specifications: 710 mm, men's style, trademarked as "Flying Pigeon" brand. The birth of Feige brand bicycle ushered in a new era for Tianjin's bicycle industry.
