Which effect is associated with a lower bike saddle regarding knee flexion?

When the bike saddle is lowered, it allows for greater knee flexion during the pedaling motion. This is primarily because a lower saddle height decreases the distance between the saddle and the pedal at the bottom of the pedal stroke. As a result, the knee has to flex more to bring the pedal back up to the top of the stroke. This increased knee flexion can help improve the biomechanics of pedaling by allowing for a more efficient range of motion and potentially reducing stress on the joints.

In the context of cycling, optimal knee flexion is important for effective energy transfer, comfort, and to prevent injuries. A saddle that is too high can lead to inadequate knee flexion, resulting in less efficient pedaling and potential strain, while a saddle that is set too low may cause discomfort and other issues. Understanding the relationship between saddle height and knee flexion is essential for both performance and injury prevention in cycling.
