Ford Motor Company has registered a US patent for what it calls a ‘bicycle derailleur apparatus for controlling bicycle speed’, and it is a genuinely intriguing idea that was first reported by Wheelbased.com. Filed on 22nd April 2019 and finally made public in late September, the patent depicts a front derailleur for a bicycle, devoid of cables, and instead, uses two Nitinol wires to provide the movement needed to shift gears. 

This diagram shows the mechanism attached to the seat tube (110) with the Nitinol wires (126 and 128) acting as a bridge to connect the derailleur cage. (Image credit: United States Patent and Trademark Office)
