he “Rotation” was designed for the International Bicycle Design Challenge and Yirong Yang’s entry was definitely worth the research. This concept “rotation” bike is a city bike that rotates and folds as it was designed to do. Due to its collapsibility and unique folding design, you can ensure the bike is the shape you want it to be in when you choose to ride. Folding it along its axis will allow you to change it from unicycle to bicycle; depending on your adrenalin requirements for the day that is. We don’t think I’d necessarily be ‘unicycling’ around the block anytime soon! What we admire the most about this concept design is the fact that you can simply fold this bike up and carry it around. Our compliments to Yiron.
