Ford has been granted a US patent for, and we quote, a “Self-propelled unicycle engagable with vehicle”. The patent application illustration shows the vehicle’s rear wheel removed and installed on the unicycle, and off you go.

While we cannot think of many situations where you would deliberately disable one vehicle just to enable another, according to Ford, the unicycle is their concept of a multi-mode transport for urban areas.

Considering how dirty car wheels get, and the effort of jacking your car up just to ride your electric unicycle, we think this should be filed under “it seemed like a good idea at the time”.
