Hi I've tried to bring this motor up a couple of times.
http://www.leafbike.com/products/e-bike-hub-motor/gearless-20-24-26-700c-28-inch/newest-48v-1500w-rear-spoke-hub-motor-electric-bike-motor-998.html
I seen it said 90.5% efficiency, 731 rpm and 35mm magnets. So my main question is this a new 9c 35mm stator motor?
Most motors say somewhere in the 80's for efficiency and 600 rpm, so I'm wondering if this means this motor has thinner laminations of the magnets? It also sais it has maximum copper fill. Would this motor give the crystalyte 35 series a run for there money?
Is this the same motor?

I've been actually talking with leafbikes through email tonight. This is what I've been able to get outta them.
bottom to top..
Well I guess that answers the question of why this one has 731 rpm when the rest seem to be at 600. It just has a lower turn count. That's probably the only thing that makes it "NEW".

Do you also make a front one?
I plan on using for a fat tire bike 26"x4".
Can you mount on 26"x4" rim 12g spokes?
Do you have different windings available?
What is the thickness of the magnet laminations?
thanks
