The point on motorbikes was you could change a wheel without removing the chain, the wheel just attached to a hub like it does on a car.
I presume from the pics the wheel is on a ‘hub’ with an axle that passes through the frame, then on the other side you have another ‘hub’ with the disk mount and freewheel.
It’s no worse as an engineering solution, just the brief is solving a problem that doesn’t exist.
