I'm kind of a chubby guy and needed a little more seat for my lot more butt. I put this on my exercise bike, because the one that came with it was too small and too hard. This seat is just perfect for that- I do not have trouble moving my legs as previous reviewers have stated- the range of motion is just fine, but as I stated before this is for an indoor exercise bike. There was no road testing. The only thing that it has done for me is make it possible to stay on my bike longer. If it were to break, I would definitely buy another one.
