The Copen­hagen Wheel

Element - - Contents -

Com­ing out of MIT, the Wheel trans­forms a nor­mal bi­cy­cle into a hy­brid-elec­tric one. It har­nesses the en­ergy lost through brak­ing, and stores it in a com­pact bat­tery on the back wheel, to be re­cov­ered later by an elec­tric mo­tor. It also as­sists the rider by giv­ing feed­back on road con­ges­tion, con­di­tions and pol­lu­tion.
