I rode one during the open house a week or so back. I really liked the bike, but it is tall. I'm 5'11" and I was on my tip-toes at lights (wearing engineer style boots).
Overall I thought it was a great bike and could easily see doing a lot of long riding on it. Others mentioned during their rides on the demo day that the rear brake felt a little soft, which I would have to agree with. Or at least at first I did, but by the end of my 30 minute ride or so, I didn't seem to notice it as much. I would guess there would be an adjustment to make it feel a little more firm.
