I’m not sure what kind of technology they use. Here is a link to an article on their website where they speak a bit about the product: https://www.motioncomposites.com/en_ca/community/blog/motion-composites/grade-aid-the-one-thing-your-wheelchair-is-missing#:~:text=A%20grade%20aid%20is%20an,ramp%20at%20a%20comfortable%20pace.

This could either be build into the hub of the wheelchair wheels, and activated and deactivated by something constraining the movement of the freewheel assembly, or a small wheel containing a freewheel mechanism could be clamped directly against the tire (similar to the way that some wheelchair brakes work) that would allow the wheel to roll in one direction only. I would love to provide some sketches of ideas if there is a way to facilitate that.
