This bike concept, called the MOOBY by designer Madella Simone. MOOBY plays with the word mobility to show that this fun one-speed is up for the challenges of urban riding. It even offers a "paneled, modular system that makes it possible to easily re-skin your ride with personalized graphics." That means that you can change the look depending on your mood. The hope: that more riders will be drawn to the fashionable style and opt for 2 wheels over 4!
