You could also duplicate the six fyx kit with a thread on freewheel for less money. With used parts and a set of dmr chain tugs with a derailleur hanger, you could easily do a 5 or 6 speed conversion for under 100 bucks. Granted, you could probably locate a used road bike for that too. In my experience, internal gear hubs that will fit 120 rear spacing don't offer a low enough low gear, and aggressive pedalling while standing isn't the best idea with this type of hub. Thats just my .02.
