Kind of odd. High angle universal joint setups are not desirable. The offset motor with the planetary reduction also is odd unless you want to give up a place to put your feet AKA the old opposed twins BMW built in the past. Why not put a regular helical gear reduction on the motor, offset the gearbox to whichever side you want the output shaft on and put the motor in the center of the chassis and run the propeller shaft directly back to the rear drive. The layout of a regular two or three gear in-line reduction box would get everything "balanced up" and would be shorter in length than a planetary. Looks like a patent looking for a problem. Maybe they should look at a Can-Am Ryker 3 wheeler to see how to do it.
