Who invented the bicycle? Please, great gods.

It is universally acknowledged that in 1839, an Englishman Macmillan invented the pedal bicycle, and there are different opinions about the invention of the bicycle. China was the first country in the world to invent bicycles. The ancestor of bicycle was a unicycle in China in more than 500 BC. During the Kangxi period of Qing Dynasty (1662 ~ 1722), Huang Lvzhuang once invented bicycles. "Grand View of unofficial history in Qing Dynasty" has been published for eleven years: "Huang Lvzhuang built a two-wheeled vehicle, which is more than three feet long and can sit for one person without pushing or pulling. When walking, turn your arm around the axis, then walk as before, and walk 80 miles around the sun with your arm. " This is the earliest bicycle in the world. Bicycles were invented by western Europeans. In A.D. 1790, the Frenchman Sifrak developed a wooden bicycle without handlebars, pedals and chains. The car is shaped like a wooden horse, with two wheels nailed to its feet and 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 by himself, with his feet on the ground and pushing back hard to make the bicycle move straight forward. 18 17, the German baron von delaisse invented a handlebar that can move freely, making his bicycle easier to replace. Delaisse applied for a patent in Britain. 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. 186 1 year, one day, Michelson, a Parisian carriage and stroller manufacturer, repaired delaisse's bicycle. After the repair, they found it difficult to put their feet on the ramp, so they improved it, and installed a pedal crankshaft on the front wheel of the car, thus inventing Michelle's bicycle, which soon began mass production. Around 1870, a Frenchman, Ma Zhi, made a bicycle with a big front driving wheel and a small rear driven wheel. This kind of bike runs well. 1890, Humber Company of England produced a chain-driven bicycle, diamond bicycle, which has been in use ever since. Bicycles were invented by Russians. 180 1 One day in September, Artamonov, a Russian serf, traveled 2,500 kilometers to Moscow to present a gift to Tsar Alexander I. The bicycle made by Artamonov was similar to that made by Sifrak in France. When Alexander I saw the bicycle made by Artamonov, he immediately ordered the abolition of his slave status.
