We thought we had canvassed the entire history of mystery monowheels several months ago with our post on the Motoruota, but as this recent photo from the Steampunk Vehicles tumblr blog shows, we haven’t yet seen them all. As is typical with tumblogs, the image came without any information, so all we can say for sure is that it does not match the design of any monowheels we’ve seen to date. Aside from the configuration of the fuel tank and seat (both mounted directly to the inner ring rather than on a framework), we don’t see the rollers to position the wheel, as we saw with the Motoruota and Nilsson monowheels. Any ideas?
