Although we are all familiar with the unicycle, a one-wheeled vehicle invented in the 18th century as an offshoot of the Penny Farthing bicycle, there must be another one-wheeled vehicle in operation. However, this does not mean that the inventors did not attempt it when the Dynasphere saw a one-wheeled vehicle in the 1930s that would revolutionize the automotive industry.
Who Made It & Why?
The Dynasphere was invented by Dr. Ing. JH Purves, hoping to revolutionize modern transportation, described his invention as a spherical movement. It was considered a remarkable invention at the time and was iterated twice over prototypes. The larger of the two Dynaspheres should have a 2.5 HP petrol engine while the other one was powered by electricity. The Dynasphere was so big that there was room for at least two people, probably the driver and a passenger. Dr. J.H. Purves demonstrated how the prototypes worked on a beach in Weston and is featured in the video below, while an edition of Modern Mechanics in an interview with Dr. Ing. J.H. Purves.
According to Modern Mechanics the Dynasphere worked with a track that ran completely inside the wheel. The motor was attached to the rail so that the rail was pulled in that direction when the engine started. So the wheel could move forward.
How did not it tip?
The device's gravity was low enough to prevent unnecessary tilting. Then combine the weight of the driver and the attached motor and the Dynasphere would stay parallel and upright.
How did you see that with the grid? For miles per hour, the lattice would simply disappear as if it were not there because the wheel was moving fast. The driver would end up with a clear view of the road, as the latticework would merge seamlessly.
Why did not it prevail?
Although there is no specific reason to understand why the one-wheeled miracle did not prevail, it was not due to lack of trying on Dr. Wilson. JH Purves's part. He not only designed two Dynasphere prototypes, but also developed a version of it to accommodate more passengers in 1
