How was the bicycle invented?
In 1869, after Renault saw French bicycles, Renault thought it was too heavy and began to figure out how to make it lighter. He used to tighten the wire spokes rim as the wheel; at the same time, the use of thin steel rods into the frame, the car front wheel is larger, smaller rear wheel. Thereby reducing the bicycle's own weight. From the beginning until the Reynolds, Xifulake, they produced 5 types of bicycles and modern bicycle big difference.The really modern form of bicycles was born in 1874. In the year, Luo Song, the British, made a unique choice of chains and sprockets on his bicycle and pushed the car forward with the back wheels. But it's still big front wheels and small rear wheels. It doesn't look coordinated and unstable.In 1886, British stahly, is a mechanical engineer from the mechanics, kinematics point of view to design a new bike style, bicycle mounted on the front fork and brakes, front and rear wheels of the same size, in order to maintain balance, and made the diamond frame with steel, but also the first use of rubber wheels. Stahly not only improved the structure of bicycles, but also restructured a number of machines used in production of bicycle components, opened up broad prospects for promotion and application of mass production and bicycle, so he was later known as the "father of a bike". The bicycle models designed by Michael are almost the same as those of bicycles today.
In 1840, Mcmillan, a blacksmith in England, got an old, cute little pony". He put a crank on the axle of the rear wheel and connected the crank with the front pedal with the connecting rod, and the front and rear wheels were made of iron, big front wheels and small rear wheels. When the cyclist steps on the pedals, the car will move itself and run forward. As a result, the cyclist's feet really leave the ground and alternate with the feet to make the wheels roll, greatly improving the speed of the vehicle. In 1842, Mcmillan rode on this kind of car and ran 20 kilometers a day. Because of carelessness, he stepped too fast and knocked down a small girl on the road. Therefore, he was caught by the police and fined. The charges were barbaric cycling.In 1861, France Michaud and his son, the original occupation is the carriage repairman, they can turn the pedal board installed on the front wheel; the car in front of the saddle rack above, unless such cycling technology superb, otherwise not hold the handlebar, falling from the car. They named the two wheeled bicycle "the name of the bicycle" and displayed it at the Paris fair in 1867, which opened the eyes of the audience.
New things that appear just aren't always perfect. Siv Lark was not discouraged, and he continued to think of ways to improve. Unfortunately, he died of illness soon.In 1818, a German named Lin delaisse, he from the woods east of the village every day, go to another forest west of the village, so every year. He thought: "if people sit on the car, stop and go, do what they like, isn't it natural?" Delaisse began making wooden wheels, like Siv Lark's almost. However, with a control direction in front of the car handle, can change the direction of. But to ride the bike, still use two feet, a little tread on the ground, in order to push the car forward rolling. When the delaisse ride out a road test, many people have been ridicule. Despite all this, he still loved the cute little cub he created".
In 1790, a Frenchman named Siv Lark, he was very fond of thinking. One day, he was walking on a street in Paris, because it rained a lot before, and it was difficult for me to have a lot of rain on the road. Suddenly, a four wheeler rolled up behind him. The street was narrow and the carriage was wide. Siv Lark hid and escaped. Luckily, he was not knocked down by the car, but he was covered with mud and rain. When others saw him, he felt sorry for him, and angrily scolded him, wanting to call the carriage to stop and talk over reason. But Siv Lark muttered, "stop shouting, don't shout, let them go."." He was still standing on the side of the road, as the coach was far away. He thought, "the road is so narrow, and there are so many pedestrians. Why can't we change the structure of the carriage? We should cut the cart along half of it, and the four wheels turn into two wheels."...... If he thought so, he would go home and start designing. After repeated trials, in 1791, the first ride on the "Trojan horse wheel" car built. The car has two front and rear wooden wheels, with beams in the middle, and a stool on it, like a toy. Because the car is not on the drive chain, the rider feet pedaling, the car can slowly forward, and the car also turned to the device, only straight, do not bend, go out to ride soon sweat.
