Who invented the bicycle pneumatic tire?

Nowadays, bicycles spread all over the world like a flood, entering thousands of households. But few people know that bicycles were invented by a German ranger named delaisse (1785- 185 1). Delaisse used to be a forest ranger. He had to walk from one forest to another every day. Years of hard work on foot 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 unicycle with two wooden wheels, a saddle and a handlebar, which is connected to the front wheel for control. People sit in cars and drive wooden wheels with their feet. In this way, the world's first bicycle came out. 18 17, delaisse rode his bike for the first time and 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 car took 15 hours. However, no manufacturer is willing to produce and sell this kind of bicycle. 1839, Macmillan, a native of Scotland, 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 emerged, such as windsurfing bicycles, water treadmills, ice bicycles and five-wheeled bicycles, and bicycles gradually became popular means of transportation. With the emergence of pneumatic tires and chains, the structure of bicycles is becoming more and more perfect. Who invented the bicycle has been arguing endlessly. However, it is recognized that in 1839, an Englishman Macmillan invented a pedal-driven bicycle. Before that, bicycles used pedals to move forward.
