Moonlander runs 4.8″ tires on 100mm rims. Such a large footprint allows you to ride them at very low pressure, which (as with a snowshoe) enables unparalleled traction and float over all kinds of terrainwet stuff, roots, rocks, pebbles, gravel, sand, and many types of snow. Moonlander, like its name implies, is meant to go beyond where normal bikes, even normal fat bikes, can go. It is designed from the ground up to ride where there are no roads, no trails and no people.

Like all of our framesets, Moonlander is made of 4130 cro-moly steel, with tubing designed specifically for this frame. The frames geometry is not unlike a standard mountain bike, with a bottom bracket height that supplies plenty of clearance for bushwhacking and monster-trucking while remaining low enough for a stable ride. The toptube maximizes standover height while keeping the headtube fairly high so you can set up your rig with a comfortable, all-day-grind riding position.
