Just wondering if anyone has experience with Fat Bikes? I've been looking at them online and watching some videos, but I'm wondering how bad the rolling resistance is on those things vs. a 'regular' mountain bike tire. I was looking at maybe buying a Surly Moonlander for cruising some heavy sand trails here in Florida and also doing some beach runs. Since the bikes carry a pretty hefty price tag (for me), I'd like to know just how much those tires make you crank up the effort? We've got miles and miles of trails here in Florida to ride. Is 'bike-camping' with one and some 20-40 mile rides a possibility or are they pretty much good for not much other than a couple miles of ripping through some tough terrain?
