In recent years, both Shimano and Campagnolo have introduced electronic gear-shifting systems for bicycles – instead of relying on steel cables, the systems wirelessly transmit signals from the user-operated shift levers to powered shifting actuators on the front and rear derailleurs. Now, a group of engineers from UK-based Cambridge Consultants are taking things a step further. They’ve developed a smartphone-based electronic automatic transmission for bikes.
