Toyota's New Bicycle Shifts According to Rider's Thoughts

The Prius X Parlee bicycle, which allows riders to shift gears by thinking “up” or “down.”
Would you ride a bike that shifts gears as you think about them?  The Prius Project is developing just that.  Using electrodes connected to a rider’s helmet, the Prius X Parlee bicycle picks up on neuro-electrical activity, subsequently changing gears via a thought-controlled interface.  Riders need only think the words “up” or “down” to engage an electronic gear shifter mounted under the bike’s seat.
