Great info on long term performance of the N360 Denman I share your preference for how the Nuvinchi changes gear over a derailiur.To me adding the harmony electric shift mech has really shown what the Nuvinchi can do other shift systems can't do, you simply pedal along at your chosen cadenence and enjoy the ride.
The derailiur mech and its narrow flexible chain was never designed for the stresses of crank driven e bikes, I doubt any mech would last 30 years on a crank drive ebike.
I would not dream of using campy or ultegra quality kit to take the pounding an electric motor would subject it to.
The compelling argument for me was it compensates for the lack of torque sensing on the BBS motor, for less experienced riders it eliminates missed shifts wrong selections that can place you into a hazard situation on the road you could have avoided.
The drive line efficency and complexity argument kind of goes out the window once you decided to add a motor to a bicycle, lets apply the same logic to modern cars.
Would you really want to drive a car with a live axle, chain drive, crash gearbox, manual advance retard ignition etc, ok you may be transmitting 99% of the engine power to the live axle vintage car but the convenience of how a modern car performs has never made me think twice about the inefficency and power losses it creates.
The bicycle without a motor is a beautful efficient means of human powered transport the more I play around with e bikes the more I admire what a bicycle does so simply.
For me with age has come knee problems if I push too hard on my normal bike my right knee hurts a week later, so e bikeing has been a great way for me to continue cycling my very hilly local rides.
I regard the e bike as quite a diffrent animal to a bicycle, as such a different kind of transmission system is very applicable to use.
The power losses are less important to me than the smooth jerk free take up of power and ride experience I now enjoy, it is very swift in use with that extra boost of a thumb throttle when needed.
Depending on my battery config used I sweep along effortlessly like I did as a young very fit rider in my 20s and it feels great, after 10+ miles the low voltage sensors beep and its time to lower power settings and return to normality.
My super human lipo power legs desert me till the next recharge, but that inefficent complex Nuvinchi/BBS 02 combo is very enjoyable while the electric assistance powers it all along.
