The Kryptonite lock is an Ingersoll Rand-owned brand of bicycle lock for securing a bicycle to a pole or other fixture, when the owner wants to leave the bicycle in a public place. The basic design, made of hardened steel of circular cross section bent into a U-shape with a removable crossbar, has been emulated by numerous other manufacturers, and adapted with variations in size and shape for other applications, such as locking motorcycles.
The product was named after kryptonite, the fictitious substance that can thwart the powerful comic-book hero Superman. The name is used under a limited trademark agreement with DC Comics dating back to 1983.

Famous quotes containing the word lock:
“There warn’t anybody at the church, except maybe a hog or two, for there warn’t any lock on the door, and hogs likes a puncheon floor in summertime because it’s cool. If you notice, most folks don’t go to church only when they’ve got to; but a hog is different.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
