The geniuses at MIT have created a new wheel that turns your regular pedal-powered bike into an electric hybrid. All you have to do is swap your back wheel for the Copenhagen Wheel, which has a sleek red hub to house all the technology. Download the app to your smartphone, and you’re ready to start riding.
The smart wheel learns how you pedal and then stores energy when you’re braking or going downhill. The motor—which provides up to 10 times the power you’re capable of putting out—automatically kicks in when you need a push. You don’t have to spend several thousand dollars on another bike—just get the wheel and you're ready to go electric.
