KryptoniteFor over 40 years, Kryptonite has been the leader in action sports security. As the creator of the original bicycle u-lock in the bicycle security category in 1971, Kryptonite has set the standard for premium quality security products. As impressive as our products are, the Kryptonite story itself is also pretty cool. From the early days in a VW van, to the legendary NYC stories, to the numerous prestigious awards the company has received for design and innovation, the Kryptonite story is about much more than a product.
