Rather than designing "for the disabled", start from the principle that a technical aid can also be of service to an able-bodied person.

What would an electric wheelchair look like if it became a small urban vehicle for everyone?

This process of expanding the need and the market can enable you to progress towards a product that will be better accepted by its users, because it will be positioned in non-stigmatizing product universes: an exoskeleton resembling sports equipment gives a modern and dynamic image of its user, and not the image of a disability; similarly, a wheelchair resembling a small urban vehicle gives an active image of its user.
