MOTOR CYCLE HAS JACKKNIFE CHASSIS (Feb, 1936)

MOTOR CYCLE HAS JACKKNIFE CHASSIS

To allow easy access to its motor, the body of a motor cycle recently constructed by a French inventor unfolds like a jackknife. A metal frame, which supports the driver’s seat and covers the motor, is attached to the chassis so that it may be tilted straight up in the air, exposing the motor to full view. No extensive adjustments are necessary preparatory to raising the frame, and the tilting may be done in a few seconds, it is claimed.

    Pretty wild concept – well before its time. Wonder why no one ever tried it again?

    Wordwrench: Maybe because it looks to be unnecessary heavy and complicated and IMHO doesn’t offer any real advantage against normal tube frame?

    @ Jari – In steel maybe but what about carbon fiber?
