The One Wheeled Vehicle
was Charles F Taylor's invention that culminated in the development of working prototypes
. The site contains 3D models
explaining the concept.
With no electronics, the machine was stabilised electro-mechanically with the use of the humble gyroscope
, but the One Wheeled Vehicle is certainly not the only example of a "Gyro-Car".
The Brennan Gyro-Monorail
is surely worth a mention, as is the 1961 Ford Gyron
, and the wonderful Schilovski Gyrocar
