Audemunie Aero Max

The Audemunie FatTrack 26″ Fat Tire All-Terrain Bike is built to go where no other bicycle can follow — through deep snow, soft sand, muddy trails, and loose rocky surfaces that would stop a conventional mountain bike immediately. The 6061 aluminum frame in Arctic White is specially engineered with a wide bottom bracket shell, oversized chainstays, and reinforced dropout spacing to accommodate the massive 4-inch-wide tires that give fat bikes their legendary all-terrain capability. These enormous tires run at extremely low pressure — typically 5–15 PSI — creating a giant contact patch that floats over soft surfaces and provides extraordinary traction that defies seasonal limitations on cycling. The wide 135mm front fork and 190mm rear spacing provide the structural integrity needed to handle the loads of aggressive fat bike riding. A 9-speed Shimano drivetrain provides a smooth, functional gear range for variable terrain without the complexity that harsh conditions would compromise. Mechanical disc brakes with oversized rotors deliver reliable stopping power on slippery surfaces. The wide riser handlebar and mountain-style stem provide confident control at low speeds on technical surfaces. Sealed bearings throughout resist water, mud, and snow ingress. The Audemunie FatTrack is the bicycle that eliminates the concept of bad weather riding conditions.
