History
The Kryptonite lock was developed in 1972. Before then, the only comparable security available was from a chain, which could weigh almost as much as the bicycle. (A common humorous observation in bicycle magazines at the time was that the total weight of a bicycle plus chain was constant regardless of cost, since owners of more expensive, lighter bicycles would buy heavier, more secure chains.) In the early 1970s the only proven method to secure one's bicycle was by the use of case hardened security chain with hexagonal links, but some cyclists were making the mistake of using inexpensive chains or cables that could be breached by thieves using commonly available tools. Indeed, local hardware stores would often sell inexpensive chain cut to length using simple bolt cutters. The first Kryptonite lock model was made of sheet metal cut and bent to shape, but the company soon went to the now universal circular cross section.
In an early test of the Kryptonite lock, a bicycle was locked to a signpost in Greenwich Village in New York City for thirty days. Thieves stripped the bicycle of every part that could be removed, but the lock resisted all attempts to break it. The innovative U-shaped design of the Kryptonite lock was subsequently adopted by several other manufacturers, with varying degrees of security. U-locks can often be seen holding naked rusty bicycle frames without pedals, gears, or wheels to bicycle racks.

Famous quotes containing the word history:
“When the coherence of the parts of a stone, or even that composition of parts which renders it extended; when these familiar objects, I say, are so inexplicable, and contain circumstances so repugnant and contradictory; with what assurance can we decide concerning the origin of worlds, or trace their history from eternity to eternity?”
—David Hume (1711–1776)
“The second day of July 1776, will be the most memorable epoch in the history of America. I am apt to believe that it will be celebrated by succeeding generations as the great anniversary festival. It ought to be commemorated, as the day of deliverance, by solemn acts of devotion to God Almighty. It ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires and illuminations, from one end of this continent to the other, from this time forward forever more”
—John Adams (1735–1826)
“History is more or less bunk. It’s tradition. We don’t want tradition. We want to live in the present and the only history that is worth a tinker’s damn is the history we make today.”
—Henry Ford (1863–1947)
