Many cruisers have a kick-back brake in the rear hub. they are intended for slow rides at the beach, so a back-pedal brake is often enough. More and more, many customers like the style, and are buying multi-speed cruisers. The old way was to "upgrade" to a simple 3-speed IGH, or a 5,7,8,11-speed IGH, if you wanted to get fancy.
Because of this, you can buy a Sturmey-Archer or Nexus 3-speed IGH that has a band brake, or a drum brake on the rear wheel, since these frames often don't have the mounts for a V-brake, or...especially a disc brake.
This guy is customizing a truly rare vintage frame, so I understand why he wouldn't want to drill, cut, or weld onto it...so it can be completely restored later if anyone wants. So...how to add a brake to the rear wheel?
Solid fixed cog on the rear wheel, so it runs a live chain (if rear wheel is spinning, the chain is spinning). Then he adds a freewheeling crankset (like all the mid drives around here), and then finally, he adds a disc brake caliper to a large diameter chainring. Using a sprocket as a brake rotor is sometimes called a "Sprotor" in custom motorcycle circles.
