bstender writes: "The Copenhagen Wheel — a revolutionary new bicycle wheel that not only boosts power, but can keep track of friends, fitness, smog and traffic.
"The Wheel uses a technology similar to the KERS (Kinetic Energy Recovery System), which has radically changed Formula One racing over the past couple of years,” says Ratti. "When you brake, your kinetic energy is recuperated by an electric motor and then stored by batteries within the wheel, so that you can have it back to you when you need it. The bike wheel contains all you need so that no sensors or additional electronics need to be added to the frame and an existing bike can be retrofitted with the blink of an eye.""
