KRYPTONITE was born in Massachusetts, USA in 1971 and started manufacturing security locks. After that, we embarked on security locks for bicycles, repeated tests in metropolitan areas such as New York, and developed an innovative U-lock system that made its name known to cyclists around the world. Since our founding, we have been manufacturing innovative locks with reliable quality that has not changed since our founding, and that are compatible with cutting, picking, and other destructive work, and delivering them all over the world.
