I’m not sure what the “next hardest” wheel configuration but compared to the last bicycle Palate Cleanser with square wheels, this seems to be a bit harder to ride for those with back issues. That said, still looks FAR more “stable” than what I would have thought:
Why stop at square wheels? After the success of last month’s square-wheeled bike design, The Q went back to the drawing board to see if they could come up with a bike design featuring triangular wheels. They succeeded, and unlike the square-wheeled bike, these triangular wheels actually roll like round ones. It’s an idea that seems either impossible, or at least like it would be incredibly uncomfortable to ride.
But by slightly curving each side of the triangular wheels and engineering a pair of articulating (but limiter-equipped) arms allowing the center of each wheel to move up and down, the bike can be ridden without the rider experiencing hardly any up and down movements at all.
Still, I’d rather use a normal round tired bike than being the “unusual” one – just too many joints, at this stage of my life, that are aching to fail.
