One-Wheeler
The Dynasphere, also known by the name “Jumbo”, is an electrically driven wheel that was invented by J. A. Dr. Purves of Taunton and his son in the 1930s. The doctor was inspired by one of Leonardo da Vinci’s sketches. Purves thought that his creation was the ‘vehicle of the future” simply because it reduced driving to its most basic form.
The first model had a basic engine that was used to push it forward. If you needed to turn the vehicle, the driver would have to lean to the side and tip the wheel to go in another direction. The wheel also had to have a low center of gravity to prevent it from tipping over. Two years later, Perves developed a bus version to hold more passengers.
