Ive put a aw 3 speed alloy wheel onto my Concept city folding bike. It was single speed. But had tabs on the frame for the cable. Its on my City boy thread.
Ive got a few hubs still. Some 28 hole ones. Including a AG 3 speed Dyno hub from my BSA Twenty. Two of S3B 3 speed with small diameter drum brake, from Raleigh RSWs. A Duomatic 2 speed kick back coaster hub from a Moulton.
Also got some new SA gear cables. Various sizes of cogs. And other SA parts.
I have a spoke threading machine. was going to build the AG onto a 406 rim for my BSA.
Im getting rid of all my stuff. But the problem for you is that Im in Scotland. And I dont want to post things overseas
