U can see the stud ends, welded to a steel plate cut in a circle and drilled to fit puch mag bolt pattern.
Trimmed the NC hub around the spokes to fit into the mag center.
Welded 5 coupler nuts around the NC to bolt the rim on like a car. I shaved the heads and welded it for a smooth look. The plate is 3/16” and welded around the center too. It’s a 1978 NC50 Express with the tiny output axle. If u have the larger axle, an urban Express wheel laced up to 16” wheels and a good bicycle tire, moped tube. 20x2.0 tires, they hold about 95psi to keep from bottom out or ejection seat wooOoklunk
