My last two commutes (36-42 miles route trip) were done on my new fatbike. While they are fun to run and really do smooth out the bumps, they are slow. I would not use one as my every day commuter, but I do plan on using it to commute throughout the winter.

A good example of how they smooth out the bumps was my commute home yesterday. Coming down a hill, as I rounded a corner, I saw a bike eating pot hole too late to avoid it. If I'd been on any other bike, I think I would have gone down hard. On the fatbike, I slightly popped the front wheel and let the rear wheel do what it wanted. I barely felt the pot hole and did not have any issues keeping the bike in control. I was glad to have been riding the fatbike.
