Found this on another website and have absolutely no idea. The person who submitted it thought it was from the 1920’s but I think it might be even earlier.
Yeah, us neither. We’ve covered monowheels (and, as one reader pointed out, motorized unicycles) before, but neither Dan nor I have seen this before, nor do we know what website the poster’s referring to. Bet it was entertaining in the mud, though - that looks a lot like a racetrack in the background, eh?
