About Cycling(Olympic ort since 1896)

Bicycles were first developed in the mid-18th century and have long since been used as a form of tra ort. Originally, the front wheel was much larger than the rear wheel, and the rider was elevated a great deal, making them difficult to control and very dangerous. In 1885, J.K. Starley of England devised the more modern bike with a chain and gearing to allow the wheels to be of equal size. Although bicycle races had been held on the old "pe y farthings", the new bikes stimulated the growth of bicycle racing as a ort.

Cycling at the Olympics features three exciting disciplines: road, track and mountain biking.

自行车概述(1896年成为奥运会正式比赛项目)

从18世纪中期问世以来,自行车一直是一种广泛使用的交通工具。早期自行车的前轮比后轮大很多,而且车座也很高,使得骑车人很难控制车子。这种情况是相当危险的。1885年,英国的斯塔利(J.K. Starley)使用滚珠轴承及链条设计出了前、后车轮大小一样的现代自行车。虽然在此以前已经有使用老式4:1式自行车的(前轮尺寸是后轮的4倍)自行车赛,但现代自行车的出现刺激了自行车赛向竞技体育方面发展。

如今,奥运会自行车比赛分为公路赛、场地赛及山地赛三种。
