I was in Stowe, VT for a few days this week for a conference and decided to try out a fatbike since there is a shop there that rents them (I ended up renting a Pugsley). It was pretty good on the well-packed snowmobile trails, but on another trail with soft snow that was not as well packed all I did was spin the rear wheel and get stuck! There were quite a few places where I had to push it. Even on the hard packed snow, I don't think I was moving much if any faster than I would have been on XC skis...think I will stick to that and snowshoeing for winter sports. It would be interesting to try riding a fatbike on the beach or dirt trails though. For those who do a lot of snow riding on fatbikes, is it normal to be that slow, or was that just me being bad at it?
