Big Iron v2
The Big Iron v2
The ultimate modern fat bike.
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.

Big Iron V2 geometry
The Big Iron V2 brings an updated and further modernized mountain bike geometry adapted for use with super-huge 27.5 fat bike tires. Using feedback from the V1, the V2 offers a slightly longer reach paired with a taller stack, which allows for what we think is best balance of comfort and control that is unique to fat bikes. The handling benefits of this setup are magnified in snow riding with a sometimes unstable front tire at low pressures. The chain stays are adjustable from 445mm to 460mm so you can really dial in the rear-end snappiness of this bike based on the tire size you choose. A lower seat tube and curved top tube allow for excellent standover height while allowing for the use of a longer than normal dropper post, but still keeps a nice big front triangle if you choose to use a frame bag for gear storage.
Because Titanium is Magic
We make our bikes form the best materials possible for the terrain we ride. For now, that means titanium, but we’re not stopping there stay posted. We use the highest quality Grade 9 3/2.5 titanium for our frames’ tubing, and 6/4 titanium for the head tube, bottom bracket shell, and machined bits all over the frame. The wonder material has so many excellent ride quality attributes: 43% lighter than steel, higher strength-weight ratio than aluminum, significantly more resistant to crash-damage than carbon, and the best vibration damping properties of all three listed here. We think you’ll agree that we achieved our goal of creating titanium frames with a modern twist by engineering guided internal cable routing, stealth dropper post routing, integrated headsets, and threaded bottom brackets. For riders who want a high-end, comfortable, fast bike built to last a lifetime, we believe a properly made titanium frame is the best option.
The Why Bikes
At Why, we believe in our products. If you are not fully satisfied with your purchase for any reason, you can return your Why for a full refund within 30 days of purchase. Of course, we ask that you respect this policy (no purposely buying a bike for a long term “rental” allowed!)
Further, we offer a lifetime warranty to the original buyer on all Why frames. This is a straightforward warranty policy- basically if you use your bike for what it was intended, and the frame ever fails due to a manufacturing defect, we will replace it for you for free.
And, to top all of that, we offer a lifetime crash replacement policy. If you crash your bike and damage it, or if you drive into your garage while forgetting there was a fresh new Why on the roof of your car, we will work with you to offer you a replacement frame at a very low cost.
