Ah, the 1930s. A time when something that could go 30 miles per hour was considered a "high-speed vehicle." The inventor of this motorized iron latticework hoop, Dr. J. H.

One can only imagine he dreamed of motorizing the caveman's wheel, and this is what he came up with. A roller-mounted carriage in the interior of the wheel holds the driver's seat as well as the engine, which transmits power to the inner rim of the hoop. The driver can steer the dynasphere by shifting the cabin to one side or the other, shifting its weight and changing its direction.
