I do not care much for hub motors just think what happens when you hit that big pot hole that looks like a puddle and you pop your tire and bend the rim. Time for a new motor.
The tweel is a neat concept and could be a viable choice if they fix the high speed vibration, noise, and heat issue. Probably could be fixed by sealing the sides and placing it under a slight vacuum.
Has anyone tried reducing the weight of a vehicle by sealing the frame of the car and filling it with helium? I know that it sounds ridiculous but if it is not under pressure the air gap in the frame will be lighter and since it is a noble gas it will not react with the metal and cannot ignite.
