'Full circle' is a compact-sized city bike that has a large wheel size (508mm, 20'') like a sprinter minivelo.
This specification makes this bike easy to navigate through a big city like seoul, while most compact bikes that have small wheels have difficulty. In short, this is a small bike with big wheels. 'Full circle' does not have chains, but free wheel gear directly connected to its pedals. It just looks like a fixed gear, but it isn't.
