The bicycle was invented by Karl Delaisse in 1817.
Karl Delaisse (1785–1851) is a generally recognized inventor of bicycles. In 1817, he made a pedal-pedaled wooden bicycle with a handle, and a steering handle was installed on the front wheel of the bicycle. This was the first time that people saw a strange car without horses, and it was also the earliest impression of bicycles.
The idea of his invention comes from the principle of roller skates. He thinks that if people put a cushion on two wheels, people can sit on it with their feet drooping and trample forward, and the car can move forward like skating. ?
In 1818, his wooden horse bicycle was officially patented by Germany and France, and became the originator of bicycles. This bicycle is made of wood, which is pedaled on the ground by people's two feet. Nowadays, it looks like a wooden toy wooden horse, which is several times heavier than the current iron horse. The invention of this wooden horse bicycle has made great contributions to mankind.

In the development history of the Wright brothers, they also tried to build a two-wheeled car first. This shows that the technology of two-wheeled vehicle plays an important role in early aircraft design.
However, as a key inventor, Delaisse has never been taken seriously. It was not until a few years ago that it was re-proposed that he was the great inventor at that time. Delaisse's way of dealing with people was so "different" that his inventions were treated coldly by his contemporaries. He also missed the opportunity to invent a bicycle. In fact, he did not invent the bicycle, but invented a two-wheeled vehicle that could turn.
Historians debunked the lie that other countries were equally leading in the research of two-wheeled vehicles at that time, and then regarded the once neglected bicycle history as a research object worthy of consideration. After many arguments, Delaisse was considered as the real inventor of this innovative technology.
