Fat, skinny, it all boils down to where and how one likes to ride. I ride lots of dirt trails, some very soft some rocky and hard road and everything that comes along. The 4" tires allow me to do any side trails the spirit moves me to which I often do and enjoy. My knobby tires are a bit noisy only on a paved road but I don't notice it anymore. Does the bike feel like a road racing skinny tire bike, of course not. It feels more like a small dirt bike motorcycle.
As for tire rolling resistance. When I coast alongside narrower tire bikes I don't believe they coast any better. If the 4" tires are aired up they only ride on a very narrow strip down the center that contacts the road no more than a skinny tire would. I would like to see some actual test stats on rolling resistance. At any rate with the E- assist it isn't an issue to loose sleep over.
I am keeping my fat tire bike. The only thing I don't like about the 4" tires is everybody asks to dang many questions.
