At $2000. u.s. when riding out the door, It's not going to happen. Especially when I have several trikes to equip with IGH's.
As can be seen from the Gear Inch Chart the very best gear spread you can achieve with a Rohloff is not getting that much of an improvement in gear range and that's running out of spec which voids your warranty. At least with the Alfine 11 speed I need to blow 3 or 4 hubs before I am reaching the cost of a single Rohloff. After more than 3 years of riding with the Alfine 11 with a mild Mid Drive there doesn't seem to be any indication of that happening.
Just heard back from Enviolo (NuVinci) they are not making a hub with 190 OLN spacing.
The Sturmey SX-RK3 is ordered & a local Machine Shop is making the adapters for me.
Photos to come soon.
