“Towable backpack” gets an aluminum frame and a big, fat tire

The Fatmate has a 20 x 4-inch fat tire that’s better for going over soft surfaces such as snow or sand. That tire is protected against punctures by a Kevlar liner, and is mounted on a wheel that features an Alex Blizzerk 90 rim, a unique sealed hub that uses a porous polymer to dispense lubricant onto the bearings, and a mechanical disc brake that’s operated by a lever on the trailer’s left handle.

The Monowalker Fatmate is presently on Indiegogo
