Objective: In this study, by means of biomechanics and kinematics analysis to discuss the motion analysis of riding bicycle, hoping to understand the effect that by adjusting the stature of saddles to change the joint angles and angular velocity in hip, knee and ankle of the lower limbs to the optimization of riding bicycle. Methods: Use two high-speed cameras to capture the motions of riding bicycle, and Kwon3D motion analysis software to proceed with kinematic analysis, then apply SPSS 19.0 version to make the kinematic parameter analysis. Results: 1.There is a significant difference in the joint angles in hip, knee and ankle of the lower limb in the same side, between before and after adjusting the stature of saddles. Before adjusting the stature of saddles, there is a right lean tendency towards the position of riding bicycles, but after adjusting, the difference in the joint angles of two sides becomes small obviously. Before and after adjusting the saddles, the angles of the right hip joint are 80.50 degrees and 88.02 degrees, of the left hip joint are 81.02 degrees and 88.41 degrees; of the right knee joint are 119.35 degrees and 123.87 degrees, of the left knee joint are 124.89 degrees and 128.73 degrees; of the right ankle joint are 110.21 degrees and 114.85 degrees; of the left ankle joint are 112.64 degrees and 117.83 degrees respectively. 2. It reaches a significant difference in compared with the angular velocity in hip, knees and ankles joints of the lower limbs in the same side, between before and after adjusting the stature of saddles. Before and after adjusting, the average angular velocity of the right hip joint are 22.16 deg/s and 28.03 deg/s, of the left hip joint are 21.13 deg/s and 27.38 deg/s; of the right knee joint are 27.90 deg/s and 32.12 deg/s, of the left knee joint are 26.48 deg/s and 30.42 deg/s; of the right ankle are 64.55 deg/s and 85.82 deg/s, of the left ankle are 76.68 deg/s and 91.01 deg/s.
