Monowheel Cart - 1940

After you have adjusted your weight for proper balance on this one-wheel coaster, it will still be a trick to maintain that balance while coasting. While essentially a one-wheel affair, the triangular frame is fitted at each corner with a set of roller-skate type wheel, which prevent sudden stops and spills in case the rider tips over too far forward, backward or sideways. When the frame is horizontal, the sets of skate rollers should clear the sidewalk by about 2 in. Beginners can start by riding the main wheel and the two rear sets of skate wheels. With a little practice enough skill can be developed to balance on the large center wheel alone.
