Designed to go where no normal fat bike can, the Surly Moonlander is for riders who want otherworldly capabilities on rocky shorelines, sand, snow, and desolate landscapes not yet discovered. While our proprietary 24 x 6.25” tires surpass the limitations of current fat bikes, the Moonlander still rides like a normal bike, making it easier (and more fun) to navigate previously unrideable terrain.
