Head-lock is a device that doubles as a helmet and wheel lock for bicyclists

Cycling is green and healthy. That is why more and more people are opting for it. With the benefits come certain inconveniences  like carrying along a helmet and of course bicycle theft. Head-lock provides a solution to tackle both of the difficulties as it can be worn as a head guard and also used as a wheel lock.

The helmet transforms into a lock when the movable white part of the Head-lock is rotated to form a sort of clasp that grips on the bicycle wheel. A number dial on the helmet is shuffled by the user to secure the bike.

Designed by Lim Seokjoong, Kim Younghye, Kwon Zion, and Na Hyesook, the Head-lock is indeed a useful device for bicyclists.
