The Dynasphere is a monowheel vehicle design patented in 1930 by John Archibald Purves FRSE  (7 August 1870 – 4 November 1952) from Taunton, Somerset, UK.Purves' idea for the vehicle was inspired by a sketch made by Leonardo da Vinci.


Two prototypes were initially built: a smaller electrical model, and one with a gasoline motor[1] that attained either 2.5[7] or 6[8] horse power depending on the source consulted, using a two-cylinder air-cooled Douglas engine with a three speed gear box, also providing reverse.[8] The Dynasphere model reached top speeds of 25–30 miles per hour (40–48 km/h).[1][8] The gasoline-powered prototype was 10-foot (3.0 m) high and built of iron latticework that weighed 1,000 pounds (450 kg).[1] The next generation version had ten outer hoops, covered with a leather lining, shaped to present a small profile to the ground.[8]
