    Well, looks good on paper. The actual world of physics may
    have a dissenting vote:

    Wellm, it is possible to make plastics with a lower coefficient of friction than steel roller bezrings. Now if you giver these plastic support pieces sufficient surface are the wear factor could concievbly be slow enough to last the olife time of the initial owner of such z vehicle.
    Electric storage in aluminum-ion batteries if I were to believe the propaganda makes for such low degredation rates that you can forget degredation.
    So physic may not come into question at all.
    Not that I will believe it until I see it.
