Express delivery-the earliest bicycle
179 1 One day in summer, many men and women gathered on the lawn of Louis XVI Palace. Suddenly, there was a bang, accompanied by a loud bang. In an instant, people saw a man named Kong Di de Chirac rushing through the middle of the croquet field. But Chirac did not run like ordinary people, but sat on a strange "wooden horse" with wheels, pedaling on both feet and doing running movements. When Chirac reached the end of the lawn, he turned the Trojan horse and ran back. People were shocked and attracted by Chirac's "wooden horse", which was called "running fast", and the real bicycle history really began from now on.
Pedal-the foot begins to leave the ground.
/kloc-one day in 0/863, a Frenchman, Pierre Michel, rode out of his house on an early two-wheeled bicycle, and all the people in the street of Saint Martin in Paris stared at him. Why? It turns out that Michio's feet have never touched the ground! Michio was the first person to ride a bicycle without stepping on two pedals. At this time, many models of bicycles weighed 100 pounds.
Rubber-free tires-400 cars sold a year
1865, Michelle's carriage shop sold 400 improved rubber pedal bicycles a year. But at this time, the bicycle is still called the "broken bone car", and its shock absorption function is much worse.
Large and small wheels-finally reduced the weight.
During the period of 1869, bicycles with large front wheels and small rear wheels appeared at the first bicycle show held in France. 187 1 year, James Starey of Coventry, England made the first bicycle and named it "Ariel". This kind of car is very light, and Starey is also called "the father of bicycle industry". Bicycles with large and small wheels are the first kind of bicycles popular in major industrial countries in the world.
Safe-popular with women
From 65438 to 0879, British H.J. Lawson developed a 30-pound two-wheeled chain-driven bicycle. The wheels are small and light, so cyclists won't roll over even if they brake suddenly. This kind of bicycle is welcomed by women, and any bicycle made according to this design idea is called "safe bicycle".
Tricycle.-for safety.
The two rear wheels are large, and the chain drives the rear wheels, which has a good balance effect and is conducive to pushing the whole vehicle forward. The tricycle manufactured by Peugeot in France in 1890 can carry 1 10 pounds of goods, which makes it have special commercial value.
Pneumatic Tire —— The First Major Improvement of Safety Bicycle
1885, john boyd Deng Lupu, a scot, successfully developed a bicycle with pneumatic tires.
Transmission device-the key to the development of light racing car
The "Deux Vicesses" bicycle produced by 1888 is one of the early two-speed bicycles. At present, from the initial two-speed to 18-speed transmission.
With the popularity of light rickshaws, in a few years, fashionable contemporary racing cars may be regarded as as old-fashioned as safety bicycles and as grotesque as early bicycles.
