Are you sick of switching gears? Want to get rid of cables forever? This prototype can help.
Engineers at Cambridge Consultants placed sensors on a bicycle crank and wheel that calculate pedaling speed and road speed. The data gets sent to a smartphone app that calculates the correct gear, then sends it via Bluetooth to a Shimano electric shifter. It’s wireless and can be powered easily for a year by a watch battery.
Sign me up, right? One detail: the price tag. A Shimano Di2 electric shifter alone sells for upwards of $3,000. Yikes. Read more at WIRED’s Autopia.
