I live in a snowy frozen wonderland and am enjoying my first winter with a Pugsley. It does not make one unstoppable. It seems to me that there are levels of snow that any bike could handle, and there are levels of snow that would stop any bike, and then there are the levels in between. The fat bike lets a person go in conditions that would stop a narrower bike, but as conditions worsen, they get to the point where even the fat bike won't go. I got it because I wanted to add a few days to the total number of days in a year when I could bike to work, and am accomplishing that goal. If I had to make a sound bite for the Pugsley, I would say, "The Pugsley makes it possible, but it doesn't make it easy."
