Too heavy for me, not to mention the efficiency - 4 drive chains and then the Nu Vinci...

Also a three stage reduction increases motor speed and so efficiency and reduces motor weight.
To answer the question, which concept is best for which choice, one should do a lot of simulation with real world simulation data. This is called "Hardware-in-the-Loop" simulation. Maybe some forum members should try to do this some time. I use "IPG Carmaker" software for this at university, which is sadly a bit pricey for a private person I guess.
I'm still keen to see you follow up on this one, though: http://www.endless-sphere.com/forums/vi ... 27#p439227
