Giving mopeds of yore a new look and an energy boost, Citydoo's Elektroon relies on pedal power to get up to speed before the electric engine kicks in. But once it does, it can hit speeds up to 40 mph and the battery will keep it going for about 80 miles. To recharge, the bike plugs into a standard outlet and six hours later, it's good to go again.
Silent and clean, it's an eco-friendly way to get around town. It's currently available only in a few locations in France for €790.
