The bike that won Outside Magazine Best Fat Bike of 2020 just got even better! Built around 27.5” fat bike wheels with clearance for up to 27.5×4.5” or 26×5” tires, this modern titanium steed will be your trusty companion on any snow or soft-surface endeavor. The crew at Why goes way back to the early days of fat biking in Alaska, and the Big Iron is the culmination of years of fat biking experience combined with modern design features, and an engineering oversight to optimize Why’s titanium tubing to the rigorous riding the Big Iron is made for. The V2 sees some updates to slightly more progressive geometry and a new UDH hanger to future-proof this bike even more.
