# Five-Bar Linkage Model of the Bicycle-Rider System

Five-Bar Linkage Model of the Bicycle-Rider System

This Demonstration models the motion of the bicycle-rider system by a five-bar planar linkage with the crank axis and the hip as fixed joints; the pedal, ankle, and knee are moving joints.

If we take the foot angle as a function of the crank angle, we end up with the crank angle as the only degree of freedom.
