I am going to say that the Uly is quite a bit taller. For a guy your height I would suggest the the Uly simply because I am 5'9" and ride an SS and I find my knees are getting sore form my leg angle. At the same time, I have only been riding the bike for less than a week, so I prolly have some "breaking in" to do of my own, so...! But seriously, check out the Uly, seems to be a pretty sweet bike!
