I recently installed a Nuvinci and a SBP shifter kit on my Micargi "General" cruiser. There was a little bit of work involved in the hub installation, so I took some pictures and I'm describing the process here. Step one - find the Nuvinci hub and a freewheel. You can find the whole wheel (already laced-up with spokes and everything) here: Amazon.com: Sun Rhyno Lite XL / NuVinci Nuvinci Gearless 26 x 1.75 36H Black/Black: Sports & Outdoors, but I found it to be cheaper to get the pieces individually. A couple of web sites have these hubs significantly cheaper than most: Tree Fort Bikes Online Bicycle Shop - Mountain & Road Bicycles | Repair & Tune-Up Sales in Ypsilanti, Michigan near Ann Arbor and Motorized Bicycles Detail Page. (There are probably other good websites, please chime in if you know of any). Then look for an english-threaded (not metric!) 16- or 18-tooth freewheel to put on the hub. I found my freewheel at a local bike shop, I'm using a 16-tooth. Then lace your hub into a wheel.
