The only time I think mine rides "poorly" is when I hit a "pressure ridge" in the road. You know one of those speedbump like deals that push up randomly. Then it's a very sharp BUMP. Probably the result of the small wheel/tire combination.
I ride mine78 miles one way to work, and I would say that overall it is reasonably comfortable. My legs get a little cramped, but I'm able to move them about so that helps. I think it would be worse if I had to keep my feet on pegs. I'm 6' and weigh about 300 pounds, and I love to ride it, even in cold weather.
Hope that helps some.
