That would be an electric paramotor. They are for sale and are roadable too. Very few pilots will admit that there are roadable aircraft available. You can walk down the street with one or you can carry it in the boot of a vehicle. You could even modify a wheel barrel to make a more useful roadable.
I hope there will be a little more capable craft than a paramotor. I think if electric will ever be efficient it has to be very lite and compact. Good glide rate and only then can you achieve some range with it.
