Cycling invention has experienced three changes:
The first generation: solid tires, driving difficult.
The second generation: inflatable tires, easy to break easy to wear.
The third generation: polymer tube, do not cheer, not afraid of rolling, good elasticity, riding light.
Argument 1:
Ancestor of the Chinese bicycle BC, 500 years of our wheelbarrow. The Qing Emperor Kangxi
(1662 ~ 1722), Huang Li-Zhuang who invented bicycles. "Qing unofficial Grand View" Juan Shiyi containing:
"Huang Lu-Zhuang manufactured in a two-wheeled car, more than three feet long, can seat one person, without push-pull, on their own.
Rows, hand rolled shaft next to the crankshaft, then re-line as ever, with enough to live on-line with the draft 80 years. "This is the world's
The earliest bicycle.
Argument 2:
Western Europeans in 1790 AD, the French Xifulake developed into a wooden bike with no handlebars,
Pedals, chain. Car looks like a wooden horse at the foot pinned two wheels, two wheels fixed to a line of
Previous. The car did not drive and steering devices, cushion is low, riding in the car, feet forward, the backward force
Pedal to make the car move forward along a straight line. 1817, Germany, invented a kind of Baron von Delaisse the free exercise of
The handlebar, so that car into a convenient location. In 1839, the United Kingdom a worker K · McMillan pioneered by crankshaft
Institutions driving the rear wheels of the pedal bicycles, make cycling both feet off the ground. One day in 1861 in Paris
Carriages and baby car manufacturers Michaud & Sons Repair Delaisse-style bicycle, the vehicle's front wheels on the placement of pedal Qu
Axis, and thus invented the Michaud-type bicycle, and soon began mass production of this bike. Probably 1870
Before and after, the French horse enforcement has created a big wheel in front, followed by
Driven small wheel bike. After 1890, Britain's Humber companies produce a chain drive with
The car for the diamond bike, this bike has been in use ever since.
Argument 3: the Russians in September 1801 of the day, the Russian serfs Artamonov riding their own making wooden
Bicycles, driving 2,500 kilometers, rushed to Moscow, Tsar Alexander I to the gift. Artamonov system
The French-made bicycles and cars were similar Xifulake manufacturing. I saw Alexander Artamonov
Manufacture of bicycles, immediately ordered the cancellation of his slave status.
