Recently, while searching the net for the most interesting forward-thinking ideas around, we stumbled across a design for an electric bicycle which works sort of like a train. Sure, that sounds confusing, but a quick glance at the pictures below will likely make the concept easier to understand. While we in no way believe that a device such as this would make any real dent in global emissions or congestion, we do think that the idea has some merit for cyclists. Consider, for example, how expensive tandem bicycles are. With a vehicle such as this, a single rider can go his merry way alone or attach extra helpers bikes as needed. Additionally, the electric machine is collapsible, which should make it easier to store when not needed. Pretty cool stuff from designer Jiang Qian in China. A quick glance at his accomplishments makes us believe we're not the only ones impressed by his work.
