Predictive automatic shifting for bikes and trikes. Avenue Shifters reads your cadence and wheel speed and shifts a standard chain and derailleur for you — no phone required. Link the app and it adds GPS grade (it sees the hill first) and live wind. It holds your gear while you coast, and the trikes drive both rear wheels through a true differential. Designed in Des Moines for returning riders, and riders whose hands don't work a gear lever like they used to. Launches Nov 12 on Kickstarter.
