16" Bikes are quite difficult for singlespeed conversion due to appropriate gear ratio. 11T is the smallest possible on regular cassette hub, but they come in 130mm OLD, not narrow. Or you go with a BMX hub, but there aren't really light ones. The Novatec hub you got is pretty much the only option. Or SRAM Automatic (see pic above), which adds some weight again. Or fixed gear.
Edit:
BTW, could you post a nice pic of your Dove, ideally at daylight/outdoors with the Kenda tire configuration? Also a pic when folded that better shows how compact (and narrow) it gets. Would make it more impressive to show it off to others.
