Bicycle Seats and Your Health

Traditional bicycle seats damage the prostate, genitalia, perineum and tailbone. Add to this a host of medical issues specific to female riders. The Spongy Wonder hornless bike seat ends all that! Two sizes, two fabric interface options, and adjustability by width guarantee no pressure on the perineum, tailbone, prostate and your “naughty bits.” Be comfortable and take great care of yourself! There are a few medial studies listed below. I stopped adding years ago. What would have been the point of adding more?
