Minimizing bicycles is one of my favourite thought experiments, so imagine my delight when I just ran into this prototype for a foldable city bike: Full Circle.
It was Korean designers Sang-hyun Jeong and Jun-tae Park’s submission for the Seoul Cycle Design Competition 2010.
The design is truly minimalist: symmetrical, built from two circles, two vertical lines and one horizontal.
The simplistic exterior contains all necessary technical stuff to make it a functional bicycle, and on top of that highly foldable. The design shows so many interesting solutions and ideas; look at the pedals for instance. Quite the engineering feat!
