Brand History

Kryptonite is an American brand. They are credited with the invention of the U-lock system! It was tested for the first time in 1972 in New York: for this, the brand attached a bicycle to a signpost in Greewnwich Village. If the removable parts were quickly dismantled by the thieves, the body of the bike remained intact for 30 days and 30 nights. This experience made Kryptonite known and launched the brand, which is now very well known in the security field. All its models are guaranteed for life.

The brand also offers an insurance system included in its locks as well as a "Key Safe" program: this program allows cyclists who own Kryptonite anti-theft devices to register their keys online and benefit, in case of loss, from a free replacement of its first two keys!
