The Wolseley Gyrocar, made in Birmingham, seen here in November 1913 before a successful test run around the streets of the city. Once started up the two-wheeler was firmly stabilised by gyroscopes which spun at 2,000 r.p.m. The inventor is the man on the left of the picture.

Fully clad in bodywork, fitted out with upholstery and with the internal gyro giving the ‘levitation’ effect…

The plans… if you were thinking of re-making it as a 3D model.
