Our results showed that the preferred knee angle used by the cyclists at the BDC position of the pedal was similar to guidelines from Peveler [1]. However, we noticed few changes of knee flexion between the four conditions of ‘posture length’. On the contrary, hip angles largely varied from backward posture to forward posture. These results suggest that the optimal fitting of the bicycle should equally depend on recommendations about hip joint angle at the BDC position of the pedal.
