I think this thread would be much more helpful if all the acronyms being used were written out in full at least the first time they are used. I've dabbled in this e-assist stuff since the early and mid-90's and I'm seeing acronyms in this thread I've never seen before. Never got further than paper napkin flow charting though. Back then Ni-CAD batteries were still a thing. Throttle was still king but some crude torque sensors had appeared. That's all changed and it doesn't look like Li-ion battery technology is going to be improved upon in my riding lifetime. About my only question is: how is it possible to have a torque sensing crank drive system? It seems like the motor assist turning the crank would make it impossible for the torque sensor to know just how much human input into the system is going on. Back when I was designing systems on napkins I ruled out both torque sensing and crank drive together for that reason. Clearly I was wrong. But why was that?
