Welcome to the new age of American Made Bikes. The American Stout is a bigger, bolder American Made iteration of our classic Mr. Big Stuff fat bike and is built using our proprietary OME technology.  The American Stout increased the wheel size from the older 26" wheelset technology to the advanced 27.5" wheelset for maximum trail and snow efficiency. The larger volume tires float more easily through snow while giving better traction and control as the rider floats through roots and rock gardens.  The American Stout is the ultimate "Do it all no matter what you need" trail mountain bike.
