I've see the posts about IGH being heavy, and this is true, but this doesn't seem to be your goal if your looking for a fat trike.
The
NuVinci is a continuous variable IGH - might not be exactly what you're looking for. I found the range limiting, but I'm an strong/fast rider (and I like the 100-year old French stuff
)
I'm familier with the NuVinci as well as it's increased weight & somewhat limited range. What I am not aware of is if they come with 190 mm OLN spacing. If they do I would appreciate a link to where I can buy them. Since our trikes are equipped with 500 watt mid drives the limited range & extra weight are not a concern. Since Fat Trikes weigh in the range of 60 lbs. possibly more with the Power Assist & Battery, the extra couple of pounds of an Internal Hub becomes a mute point & the advantages far out weigh any reason for not using them. In case it is of interest, here is a chart showing the most common IGH's on the market & their best gear spreads using off the shelf standard chainrings & rear sprockets. Numbers that could be difficult to achieve using a derailleur & cassette. (scroll down) -
