In this study, we construct the evaluation system for muscular activity of the lower limb when pedaling an electric power-assisted bicycle. The evaluation system is composed of the electric power-assisted bicycle, the numerical simulator and the motion capture system. The electric power-assisted bicycle is attached to the specialty pedal with the force sensor. The numerical simulator is the musculo-skeletal model. The musculo-skeletal model is the human model for the pedaling motion. The motion capture system is used for measuring joint angle of the lower limb. Then we examine the influence of each muscle of the human body in the electric power-assisted bicycle. First the experiment for pedaling motion is performed. Then the musculo-skeletal model is calculated by using the experimental data. We discuss which muscles are important for pedaling motion. It is found that Gluteus maximus, Vastus, Soleus and Gastrocnemius muscle are changed characteristically in the pedaling motion and the muscle activity is decreased by electric power-assist.
