In 1971, Kryptonite was born out of the back of a VW van. A year later, Kryptonite locks were put to the ultimate test by locking a 3-speed bike to a signpost in New York City for thirty days and thirty nights. While everything on the bike that wasn’t locked was stolen, the lock itself never failed. This is the perfect example of Kryptonite’s reliability and know-how. And if your bike does get stolen under the watch of a Kryptonite lock, they offer anti-theft protection.
