I did the research, your search terms came up with better searches, tho. Either way... none of the threads were definitive about whether or not hubs with internal gears would work. Only the one that I linked to above had any hope, and sure enough... the guy posted pics when I asked, and it appears that he's been riding it for a long while.the nuvinci is expensive ($300) and made for an engine (staton sells them)
I was giving examples of the search
your money, spend it this way if you want
you really need to do some research tho
I would have assumed that as long as you change gears the way the hub was designed to change gears... it's prolly gonna work.I have been using a Nexus 7 speed for about a year & a half on this bike.
I have heard the nightmares about stripping gears & so I release all motor power before I shift it. So far no problems.
