Big city cyclists need big city protection, as would-be thieves aren't intimidated by flimsy cables or weak U-locks. That's why serious cyclists turn to Kryptonite for their security needs. The Evolution Series 4 U-lock is a cut above other bike locks, with a 14mm hardened Max-Performance steel shackle designed to resist both cutters and leverage attacks. Ideal for anyone who lives in moderate to high crime areas, the Series 4 received a 9 on the Kryptonite 1-12 lock comparison system, which ranks the varying levels of security offered by the company's product range. A lock that ranks 1 on the Kryptonite scale might work if you live in the burbs and have a Rottweiler parked next to your bike or motorcycle. A lock that ranks 12, however, is built for maximum deterrence. The Series 4 also offers such security-enhancing features as a double deadbolt locking mechanism for extensive holding power; a disc-style cylinder with more than one million key variations; a reinforced anti-drill/pull cylinder protection system; and a center key location with a dual overhead cam locking mechanism that defends against leverage attacks. The Series 4 is about more than just security, however, with a sliding dustcover that protects and extends cylinder life, anti-rattle bumpers that reduce noise during transport, and versatile EZ mount transportation bracket. And as a bonus, the lock comes with three keys, one of which is lighted with a high-intensity bulb that makes it easy to unlock the Series 4 after dark. The lock measures 4 by 9 inches.

The Legendary Durability of Kryptonite Locks
The first big test for Kryptonite locks came in 1972, when Kryptonite founder Michael Zane directed the Second Avenue Bicycle Shop in New York City to lock a three-speed bicycle to a signpost in Greenwich Village. Although thieves immediately stripped all of the bicycle's removable parts, the bicycle itself remained for 30 days and 30 nights. The publicity gave Kryptonite the boost it needed and forever changed the face of bicycle security. Twenty-two years later, Kryptonite returned to the streets of the Big Apple to test its latest innovation, the New York lock. In April 1994, the New York Post laid down the ultimate challenge: Could Kryptonite's New York lock last 48 hours on the toughest streets of New York? In a city where more than 100,000 bikes are stolen each year, Kryptonite and the Post locked a brand new, bright green Univega road bike worth $600 to a parking meter in the East Village--the Bermuda Triangle of New York bicycle thievery. For a full 48 hours, the bike remained locked on the corner of Avenue A and 11th Street. Zane and Neil McDaid, director of product development and design for Kryptonite, watched from around the corner as the bike came under every possible means of assault, stumping thieves at every turn. After 48 hours the bike remained intact except for the gear derailleur, which had been stripped off. The lock showed definite signs of abuse, but it had not
