英语自行车的发明作文
【The Invention of the Bicycle】
A French father-and-son team of carriage-makers, Pierre and Ernest Michaux, invented an improved bicycle in the 1860's. Many early bicycles (called velocipedes, meaning "fast foot," or, more descriptively, "bone shakers") had huge front wheels —— it was thought that the bigger the wheel, the faster you could go. Early tires were wooden —— metal tires were an improvement, and solid rubber tires were added later. A chain with sprockets was added to the bicycle in the 1880's; this was called the "safety bicycle." Air-filled tires were also added in the 1880's. The derailleur gear system was added in the 1970's.
Nowadays,it's important for us to live the low-carbon life. So riding bicycle is the best choice for us to go around. It's not only benefit for our health and also cheaper than cars and the oil is not necessary for bicycles. The better thing is, it was so friendly to environment that it won't produce any polution. So let's go for a ride!

自行车是谁发明的?
自行车是卡尔·德莱斯发明的。自行车是卡尔·德莱斯发明的,发明于1817年。德国卡尔·德莱斯KarlDrais,1785–1851是一般公认的自行车发明人,他在1817年制造出有把手的脚踢木马自行车,在车子前轮上装了一个方向把手,这是人们第一次看到不需用马拉的奇怪车子,也是人们最早的自行车印象。
自行车的原理
最简单也最重要的就是齿轮原理,自行车的链条以及前后齿轮之间的连接是推动自行车前进的重要结构。自行车的摩擦,自行车把手与手之间的摩擦可以防滑,而轮胎与地面之间的滚动摩擦可以减少摩擦阻力。自行车龙头的轮轴远离,自行车龙头将轮轴扩大,使自行车转弯更加省力。自行车后轮齿轮与链条之间的连接属于定滑轮,可以改变受力方向,使得自行车前进。
