I am guilty of buying a mongoose beast last year, very smooth, lots of fun, heavy as a house and no gears, beach cruiser geometry. Not a commuter bike for anything longer than three flat miles in my mind, but everyones route is different. Tire pressure is everything on a fat bike, 20 PSI eliminates a lot of contact patch, but it is not as bouncy either, lots of trade offs.

Good luck,
