When we find ourselves with a deep, primal urge to explore beyond the horizons of our beloved Flat Earth, few things satiate this need. Moonlander is one of them.

A portal into previously unridden terrain, Moonlander goes where other fat bikes don’t dare, where traction is a supposed myth and the only grams worth saving are in our Dugout Bag.

Our newly developed, high-volume Molenda tires were key. (Even the fattest in-market tires don’t cut it, and that includes our own line.) Therefore, we equipped this one with 24 x 6.2-inch tires on 100mm rims. Such a large footprint allows us to ride at very low pressure, enabling the ability to float over a geographic smorgasbord of otherworldly terrain. Think rocky dunes, creeping shorelines, frozen beaches, sinuous stretches of snow and the like.

• Carefully crafted from our 4130 Chromoly steel, with a bottom bracket height that supplies plenty of clearance for bushwhacking and monster-trucking without losing out on stability
• Surly's first bike with a 9-speed Pinion gearbox, an innovative approach to spur gearing that improves reliability and go-anywhere performance with less maintenance
