自由車發展至今已逾兩百年歷史，其所扮演的角色也隨著時代變化而不同，從早期單純的交通與載貨工具更延伸為日常生活中運動、休閒等器材，因此，自由車不只提供健康的休閒活動，也解決了環境污染與經濟的問題。
本研究目的如下：了解自由車運動的力學分析、體能特性、人體關節結構特性、騎乘姿勢與人體關係。
研究方法：採文獻分析法以期探究自由車的力學分析、體能特性、人體關節結構特性、騎乘姿勢與人體關係。
研究討論：藉以釐清自由車運動發展歷史的真相，對於自由車運動發展有其必要性，並藉由科學與社會科學的對話中，頗析出具有實用價值與科普價值之自由車運動發展與傷害之研究，更進ㄧ步了解自由車運動並做為熱愛運動人們參考之依據。
研究結果：可以充分了解自由車的生活文化和特殊功能設計、自由車的設計基本概念，進而引發更多的創意且健康安全騎乘生活和樂趣，並能感受從自由車延伸出來的運動休閒文化。

　　Cycling have a more-than-200-year history, and the role vary with time, from the pure transportation for carrying passengers or goods in the early days to the tool for sports or leisure nowadays. As a result, cycling not only provide the healthful leisure activities but also solve the environmental pollution.
　　Purpose: to understand the dynamic analysis of cycling, the characteristics of fitness, the characteristics of human joint structure, and the relation between riding postures and human body.
　　Methods: Documentary Analysis.
　　Conclusions: By clarifying the truth of the history of cycling development, the necessity of development of cycling riding can be shed light on. Furthermore, in the dialogue between science and social science, it is that practical values and merits of science universality of cycling riding can be analysed in this research; Moreover, cycling riding can be understood further, and this research can be a reference for the people loving sports.
　　Results: Furthermore, the culture of cycling ; the functional design of cycling; the basic concept of cycling, design would be fully understood to encourage more creativity, to arouse more interest of cycling, and to feel the cycling-related leisure culture.
