Kryptonite is an Allegion-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. More information...
