Predictive equations to define an ideal bicycle saddle height from simple static measurements

Bicycle saddle height is implicated in musculoskeletal injuries. A typical goal for setting saddle height is a minimum knee flexion angle of 30-40° during bicycling; yet dynamic analyses are unattainable in most circumstances. This investigation yielded a predictive equation, from inputs such as bicycle seat tube angle and rider inseam height, which would define the saddle height that results in a minimum knee flexion angle that is prescribed by a professional.
