Self-Shifting Bike Prototype From Colorado State University
Ben Johnke, Bill Engelking, and Matthew Stout from CSU teamed up on a self-shifting bike prototype. As the rider picks up or drops in speed, the bicycle shifts gears to accommodate. The stock derailleur and cable system are paired with electronic sensors and computer code. When starting the bike, the rider keys in initial gearing on the bar-mounted main computer. While pedaling, a sensor reads speed as an LED light bounces off reflective tape on the rear wheel.
