Series 2 Mini-7 U-lock - Kryptonite


Created by THE bicycle security expert, this lock combines a lightweight design (1.11 kg) with a solid level of protection 6/10 (ideal for protecting mid-range bikes outdoors). The shackle is still large enough to attach your bicycle to most bike racks in town. The strength of the series 2 U-lock lies in the shackle's patented double locking system (so would-be thieves have to saw through it in two places). What's more, your purchase comes with 1 year of free Kryptonite insurance. Your bike is insured for up to €1500 in case of theft.

Brand History

Kryptonite is an American brand. It is 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 bike to a traffic sign 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 put Kryptonite on the map and launched the brand, which is now widely recognized in the security industry.

All its models come with a lifetime warranty. 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.
