The origin of bicycles! !

18 18, the Trojan horse made by German baron Carl Dulles was patented in Germany and France, and he also became a recognized bicycle inventor. He installed a steering handle on the front wheel of the car, which is the earliest impression of the bicycle, but compared with Leonardo da Vinci's manuscript, this car can only pedal on the ground with both feet, and it is made of wood.

1885, the British changed the bicycle with large and small wheels to the same size as the front and rear wheels, and adopted chain transmission, which is called Rove bicycle, which is also the basic prototype of the bicycle now. The same wheelset as now, bicycle frame, chain drive, still no brakes.

1965, the number of cars and bicycles was basically the same, both around 20 million, but now, the number of bicycles has reached126 million, twice the number of motor vehicles.

Bicycle, also known as bicycle or bicycle, is a small land vehicle driven by human pedaling. Bicycles usually have two wheels and three wheels, but they are mainly used for freight transportation and are relatively rare.
