The Yikebike Electric bikes have become more and more popular in the last decade. While most electric bike designs revolve around a motor providing an extra boost to the rear wheel, Yikebike has totally re-imagined the concept. The YikeBike lets you sit comfortably and steer with handlebars that reach around you from behind. The electric motor is all contained in the back wheel and, best of all, the whole thing folds up into a neat little package.
