Background Information 背景信息
发明自行车的是德国的一个看林人，名叫德莱斯（1785-1851）。德莱斯是一个看林人，每天都要从一片林子走到另一片林子，多年走路的辛苦，激起了他想发明一种交通工具的欲望。他想：如果人能坐在轮子上，那不就走的更快了吗？就这样，德莱斯开始设计和制造自行车。他用两个木轮、一个鞍座、一个安在前轮上期控制作用的车把，制成了一辆轮车。人坐在车上，用双脚蹬地驱动木轮运动。就这样，
世界上第一辆自行车问世了。1839年，苏格兰人马克·米廉发明了脚蹬，装在自行车前轮上，使自行车技术大大提高了一步。以后随着充气轮胎，链条等零件的出现，自行车的结构越来越完善。
