MarkT,
I honestly can't say. I've asked for detailed specs and I'm hoping to get them next week. The motor I'm looking at is the Golden Motors MW16B, if anyone knows anything about it.
cr0sh,
I've looked at Roboteq but their incredibly expensive, 150A 50v for $550 for a bldc. If I were to go brushed I'd go with the OSMC board that is 160A 50v for about $170. My hope was to simplify the physical design by using a hubbed motor. I know this will add cost and complexity to the electronics.
I did find a couple of threads over on the Endless-Sphere.com forum;

I'm studying both designs to see if I can use them, since they're intended for scooter use.
