Our His & Hers Twike commuter vehicle is completely gasoline-, emission-, and guilt-free. This cozy two-seater has a brilliantly engineered zero-emission electric power system that can be supplemented with human pedal power, as desired. Like your significant other, it's a first: the first electric-human power hybrid. Swiss and German engineers have designed it with lightweight aluminum alloys and reinforced floors, and it weighs less than 600 lbs. You will have to find another excuse for running out of gas, however; its state-of-the-art, six-kilowatt hour nickel-alloy batteries can be fully charged from a regular household outlet. Powered by a three-kilowatt electric motor, it can achieve speeds of up to 55 mph with a range of up to 90 miles per charge. When you feel like pedaling, and thereby extending its range for those romantic drives with the convertible top down, the choice is yours. The clever regenerative antilock brake system captures energy from deceleration and channels it back into the storage system to extend the range as well. The Twike has far fewer parts than any messy internal combustion engine; if only all relationships could be this low maintenance.
