Kryptonite is an American bicycle lock manufacturer founded in 1971 by Michael Zane in Canton, Massachusetts. The company introduced the first production U-lock in 1972, using hardened steel to defeat bolt cutters and establishing the form factor now standard across the category. Kryptonite publishes a 1-to-10 security rating used by cyclists and insurers to compare locks, and its New York Fahgettaboudit chain and Evolution series are widely specified in high-theft cities. The brand has been owned by Allegion since 2001. Supreme has collaborated with Kryptonite on co-branded U-locks and chain locks.
