Who said that fat bikes are just for winter riding; not us. Here are a few shots of our buddy Eric's Pugs that he just had in for some work. He has been ripping hard, getting it dirty, and subsequently ripped the derailleur off. With a new one installed and the shifting dialed in the Pugs is ready to ride another muddy trail.
With the size of those tires it like riding a bike with a couple inches of travel all around. Also with the increasing popularity of fat bikes are increasing accessory options. Think adventure touring, logging road bumping, and lost coast exploration.
