The 'Ivy' by Sono Mocci from Italy was recently shortlisted in the Seoul Cycle Design Competition 2010, a contest designed to help the city of Seoul develop a healthier cycling culture. How much better-looking is this lock than hard chain metal?
As the designer says:
Why does our bicycle need to be connected to light poles by chains like a criminal in prison? Inspired by nature, the design of this cable wire lock is a mimicry of ivy. It is unified in our daily scene and promotes protection of the environment. It is soft and feels natural. 'Ivy' is a plug to awaken the relationship between you and society. 4 dial number lock, steel wire + silicon gom covered. 2 sizes: short (900mm), long (1500mm).
