I would like all of you engineers and designers to comment on this design of bike. Tell me what you think the ridability would be like considering the hub motor is mounted on the swingarm.

not yet heard what I want to hear.

OK see if you can spot it in this video.

I don't know Rip. May be a weak upper shock mount pushing into the batteries? Too much anti-squat built-in with the downward angle of the swing arm?

Half right.
The bike has chronic "jacking" or antisquat under acceleration but not because of the suspension geometry.
Its because the motor is mounted to the swingarm.
The torque reaction in the hub motor axle feeds into the swingarm and effectively turns it so the suspension extends almost to top of stroke.
If the motor turns forwards the axle and swingarm turn backwards.
You also see the forks jacking but that is due to weight shift.
When the throttle is chopped the whole bike squats back down, front and rear.
I recently made a rear end for a trike with a Kelly motor mounted to the swingarm and it did the same thing.
Watch the KL9 in this video at 32s for an example of torque reaction.

Although, this would be bad for ground clearance .

Yes.
You cant fix this. The motor has to be moved to the frame.
BUT...that all depends on who is riding the bike.
You might have someone who likes Vodka and doesnt care about the finer aspects of suspension performance and they wouldnt even notice the rear end pogoing up and down.
But then you might have a pro downhill racer and he would get off the bike in 2 seconds saying wtf is wrong with this thing...unridable.
I would ride the bike only to find out how unridable or annoying it is ie try to quantify the problem.
