This Dynasphere video from British Pathé is awesome. The electric vehicle places passengers inside one giant wheel to get them from A to B. From wikipedia:
The Dynasphere was a monowheel vehicle design patented in 1930 by Dr J. A. 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…
The driver’s seat and the motor were part of one unit, mounted with wheels upon the interior rails of the outer hoop. The singular driving seat and motor unit, when powered forward, would thus try to “climb” up the spherical rails, which would cause the lattice cage to roll forward.
And there are more monowheels to be seen, via the Retronaut.Next, watch Cycle-Skating.
