Thx d8veh, but if I could make this fantasy come true, then I would connect a simple 3 speed shift on my left handle bar, and throttle off to shift. Since my Nuvinci speed sensor is on my output, it would see less r/m, and would auto shift to my desired motor speed - ~350 r/m - automatically. What adds another layer of issue is that my disc brake is on my Nuvinci output. Showing my ignorance here - does a Sturmey Archer 3 speed come with a freewheel, or is it attached? I hope it is the latter, because I want it to both pull and push.
Sidebar, d8veh. Are you continuing to have good service from your Xiongdang 2 speed hub? Hope so. My front hub equipped, Bikee E2, tandem recumbent install worked well, until early summer. That's when I robbed the battery for the e mini bike set up that is in the link that you can trace to, from this thread. It's currently difficult to move the battery back and forth between builds (I'm gonna work on that), so my summer transport was my trusty ol' 650 Dakar.
Thx again for past and current help....
