I have a 16" wheel folder that currently has a 44t chainring coupled with an IGH 4 speed. I am going to change to a nexus alfine 8 speed hub with 16t sprocket. In order to make it work I need to go to a larger chainring. It has a four arm/four bolt crankset. Is it possible to find a 52, 53, or 56t chainring with four bolt holes, or will I need to change the crakset to get the chainring I need?

It's probably cheaper just to change the whole crankset. Have you talked to Bike Friday? I've bought oddball parts from them before, stuff not in their catalog. Custom chainrings are available, but pricey: http://dgcustommachining.blogspot.co...hainrings.html

Or maybe ask nicely in this thread: a homemade microadaptor
