[Blue Bomber Man]

Lot of naysayers on hub motors.

I suggest people look up BluWave's hub motors, they are quite impressive: All wheel drive built in, regen breaking, and normals breaks, additionally the ECU coordinates all traction issues.

Another interesting hub is Michelins. Their's has everything mentioned before, but also has suspension built into the wheel to remove most of the unsprung weight.

As far as efficiency these motors run around 95% efficient and need no transmission and are all fully capable of highway speeds.
