Most hub motors I've seen tend to be outrunning hub motor (think of the shaft as staying still, the housing turns, the wheel bolts to the housing) making it hard to put a drive shaft in the center of it, thus it's hard to connect a traditional drive shaft to it, but I do agree on your point of making it so the components can work separately, no point in pulling the engine or tranny and having to replace the motor at the same time, make it so it can be taken appart, but it would seem to be true the other way, you don't want a $1,000 repair bill to replace a wheel bearing, but if the wheel bearing and the motor bearing are one in the same that just might be the case, also how long would a hub motor last with a bad wheel bearing?
