if I had to buy another fat bike it would be the lightest one I could find, my farley 7 with a rack weighs in around 35 lbs, it is tough to move around
it is a great bike, and I enjoy riding it,
I have seen a pivot les build that was very light, and weight would be a major consideration for me.
as it stands now my fat bike has lights on it, and reserved for winter rides only, if it came in 10 lbs lighter I would use it more during the summer
