‘The Ford Gyron was a two-wheeled gyrocar first shown in 1961 as a concept car. One wheel was at the front and the other at the rear like a motorcycle and the car was stabilized by gyroscopes. When the vehicle was stationary, two small legs appeared from the sides to support it.’
They should build it now!
Interestingly 40 years later we have MonoTracer, history repeats itself.
