There will be a lot of pressure on a relatively small wheel there, so I wonder what dust or a grain of sand would do there. I would guess making sure the mechanism near the pedals stays operating smoothly takes more maintenance than with normal bicycles. I wonder whether they considered exchanging rotary motion of the pedals for up/down movement so that they could get rid of that complex shape.
Also, given that they sell a “seatpole spare string holder“, those strings don’t seem to last as long as a traditional bicycle chain.
