A slider-crank mechanism whose coupler curve is the approximate ellipse is designed so that the human may perform the pedaling of the elliptical motion of the foot. The set of the frame, the crank of the usual bicycle and the foot, the shank, the thigh of the man's leg to be pedaling composes the planar five-link mechanism with two degrees freedom. The set of the frame, moving links and the foot, the shank, the thigh in slider-crank pedaling composes the planar seven-link mechanism with two degrees freedom. Kinematic and static analyses of planar five and seven link mechanisms above-mentioned are possible to perform with given values of the angular displacement of the foot (the pedal angle) and ones of joint moments at the hip and the knee during a crank rotation. Then, a new procedure is proposed for analyzing motion, forces and moments of components in cases of ordinary pedaling (simple crank pedaling) and slider-crank pedaling and for evaluating their performance of pedaling. Simulation results of the pedal angle, the pedal force and the crank moment are verified experimentally.
