Well I got no reply from ping or raf242 so far, which led me into further e-speculation.
As Drunkskunk pointed out, the motor starts working miracles once you plug a higher voltage in, and 6*10 motor has almost exactly half the speed of a 5 winding (superfast 2805) 9C motor.
So I simulated the 2805 motor with a 700c wheel, 72V pack and 20A controller. I hope some of you already tried 9C at 72V, so you can confirm my findings.
It looks very promising for my bike. The best aspect of this is that cruising at 80+ efficiency AND enough power available is possible from 25 to 50kph, and speed is only dependent on throttle setting and pedal input. The motor would only start being inefficient in really slow and super steep climbs, but also here it is more efficient than it was at 48V simulation. See the attached pic for various throttle settings.
So I would have a choice of speed AND power, without much need to compromise either. I would only need to get the slower motor, which is out of stock now. A 7*9 may however also do the trick, if a little too fast. Getting a 72V pack charged evenly and buying a controller that can do 72V may be a bigger challenge, but not impossible. I think the power at this voltage is ample, so I could get eway even with a 15-17A controller. Any thoughts?
