The earliest bicycles were invented by the French.
At the end of the 18th century, the Frenchman Sifrak invented the world's first self-propelled car. In 1790, it was developed into a wooden bicycle without handlebars, pedals, and chains. The shape of the car resembles that of a wooden horse, with two wheels nailed to its feet, and the two wheels are fixed in a line.
Since the bike had no drive and steering and the saddle was low, Sifrak rode on it himself, landed on both feet, and pushed hard backwards to keep the bike moving in a straight line.
The "Wooden Horse Wheel" car was built, because the car did not have a transmission chain, only by the cyclist to push the ground hard, and there was no steering device, only to go straight, not to turn, go out to ride for a while and be tired and sweaty. New things that have just appeared are always less perfect. Sifrak was not discouraged, and he continued to find ways to improve it.
Unfortunately, he died soon due to illness.
System structure of the bicycle:
1. Guidance system.
It is composed of handlebars, forks, front axles, front wheels and other components. The rider can change the direction of travel and maintain body balance by manipulating the handlebars.
2. Drive (transmission or walking) system.
It is composed of pedals, bottom bracket, crankset, crank, chain, simple hand flywheel, rear axle, rear wheel and other components. The pedal force of the human foot is transmitted by the pedal through the crank, sprocket, chain, flywheel, rear axle and other components, so that the bicycle continues to move forward.
3. Brake system.
It is composed of brake parts, and the rider can manipulate the brake at any time to slow down and stop the moving bicycle to ensure driving safety. (In addition, for safety and aesthetics, as well as for practicality, it is equipped with parts such as lights, brackets, and bells.) )
