Editor’s note: A version of this article ran in the November issue of BRAIN. It has been updated with more information about the two brands that sell products with similar features as the SRAM patent.

SRAM’s recent patent application for an “Electronic Cable Puller” points to the increased integration of e-bikes. But it also might lead to some conflict between SRAM and two U.S. companies that already offer products using technologies similar to what SRAM describes in the application.
With e-bikes surging in popularity both in the U.S. and globally, manufacturers have been considering what else a large-capacity e-bike battery could power in addition to propelling a bike. Headlights, taillights, and integrated computer displays are obvious accessories to draw juice from an e-bike battery. Magura has shown heated grips that use e-bike battery power, and Fox’s E-Live Valve uses the bike battery to control suspension.
But SRAM has its eyes on derailleurs. SRAM’s U.S. patent application for an “Electronic Cable Puller” was published on Sept 10, with Geoff Nichols as the sole inventor. It describes a wireless shifting system that’s centered around an electronic cable puller, which mounts to the frame. The cable puller is powered by an e-bike’s battery.
