This tandem two seat device was made by the French automobile company Morgan Monotrace in the years between 1926-1929. The machine was powered by a horizontal 500 cc 4 stroke single. The stabilizer wheels were raised up as the vehicle started moving. I'd say the obvious development was to make it amphibious.

I think the looks alone would be enough to curb sales- a boat on wheels, and look at that windshield!- and one wonders how seamless the stabilizer wheel activation might be. The passenger looks a bit sheepish being caught on film.
