My legs, particularly my knees, don't care for the motion and prefer a slightly lower seat.
hey, whatever works best for your knees. I, however, am the opposite. I really notice a low seat and my knees immediately feel better when a seat is at my optimal height. When too low, its like certain knee muscles or ligaments get "overworked" (for want of a better word) and they hurt. When at the right height, its an immediate "ahhhh" as they stretch out to their full extension and they feel better right away.
