The inner city bike was designed by JRUITER + studio as a project asking questions about ultra short inner city travel. What is needed, who is riding, and how far are they going.
The inner city bike rethinks what a “frame” is, getting rid of basic key components, and creating a new type of urban bicycling.
The positives are easy quick turns, huge power to the rear wheel to go over curbs and up hills, and great start / stopping / sitting situations.
