Developed by researchers at MIT in consultation with representatives from the Danish capital, the Copenhagen Wheel is a new technology that transforms your bike into a "smart electric-hybrid".
Are you interested in bicycling more, but concerned about showing up to work covered in sweat or having enough stamina to travel long distances and manage hilly terrain?
"Say hello to the Copenhagen Wheel, a device that slips onto your existing bike wheel. It stores the energy that you already use, and saves it for when you need it most. Hills become flat, and you no longer have to expel loads of energy to get around."
See an explanation of this ground-breaking technology in the video below:
