On 2000 Sydney Olympics, Jiang Cuihua obtained the bronze medal of 500m item for woman track bicycle, achieved our cycling medals in the Olympic Games zero breakthrough. Jiang Yonghua won again at the Athens Olympic Games silver medal in 500m item for woman track bicycle. 2008 Beijing Olympic Games, our athletes also won three medals, opened up a new high of cycling. Compared with American-European countries, the beginning of the research work on the bicycle simulator of our country is later. The Dalian Jiaotong University once developed a block successfully for the national bicycle team in 2003, which has raised the athletes results. But a lot of actual need has not been solved yet, under the abominable weather such as the blowing and raining, the athlete can not exercise normally, which has affected the coachs drill program; So developing this set of bicycle training simulator will play a very important role in improving the achievement of our country’s cycling. As the road conditions require simulation training simulator Peace Road, two kinds of bike uphill attitude, so racing simulator in order to frame as a basic framework, using crank - slider agencies to achieve the slope of motor and sens
