I like the motor per wheel approach and the availability of the space between the wheels for lowering the bed or batteries or whatever.

But the same could be achieved with a swingarm suspension with hypoid gears and the motor in between the main bearings of each swingarm. The motors could rev higher, the hypoid gear set would add less unsprung weight than a rim motor would, and the motors would be less vulnerable.

It would be no good for the front suspension as you cannot steer, obviously, but neither is a rim motor any good there as the the motor and steering pivots get in each others way and the total weight gets out of hand.
