Kryptonite

Kryptonite is the top name in the bike lock industry. That's why we've included three of its locks in our guide. One of the factors that set Kryptonite apart is its Anti-Theft Protection Offer. Basically, when you get your lock, you must register it with the company right away. Then, if your bike is stolen while it is covered by the anti-theft protection, the company will pay to replace your bike. For the Fahgettaboudit Mini, the first year of registration is free. After that, it is $24.99 for five years of coverage. The New York Fahgettaboudit Mini offers the highest level of security of any of Kryptonite's locks according to the company. The shackle is made of 18-millimeter hardened "MAX-Performance" steel. For extra security, the crossbar has an oversized hardened steel sleeve. The lock comes with three keys, which disengages the lock using a high-security disk-style cylinder. The cylinder is protected by a sliding dust cover. And, the center keyway is designed to make leverage attacks difficult.
