Will SRAM soon debut a self-charging wireless mountain bike derailleur with a dynamo generator inside? SRAM filed a patent on November 10th, 2022, detailing an electronic rear derailleur with the means to re-charge itself whilst in use, negating the need for even a medium-sized removable battery that requires charging off-the-bike. The 28-page document describes the use of a generator coupled to the derailleur cage that can be activated to continually charge the batteries by virtue of the rotation of the upper pulley wheel while pedaling.
