Kryptonite Evolution Series U-Lock With Cable

Kryptonite's 7/10 rating indicates this lock is suitable for moderate-risk areas. It is robust enough for quick stops in cities or longer lock-ups in quieter suburban settings, but it is not intended for high-theft urban environments where a higher-rated, heavier-duty lock would be recommended.

The 4-foot Krypto Flex cable is designed to loop through your front wheel or accessories and then attach to the U-lock shackle before you lock it to the bike rack. It provides a secondary layer of security for components that are easily removed, though it is not meant to be used as a primary locking mechanism.

Yes, the included Flex Frame-U bracket is designed to be versatile and adjustable, allowing you to attach the lock to various frame tube shapes and sizes. It keeps the lock secure and rattle-free while you ride, though you should ensure the mounting location doesn't interfere with your pedaling.

Kryptonite offers a Key Safe Program where you can register your key number online immediately after purchase. If you lose your keys, you can contact them to have replacements sent to you, saving you from having to replace the entire lock.

The Anti-Theft Protection Offer is a reimbursement program that covers a specific amount if your bike is stolen due to the opening or breaking of the lock by force. You must register your lock on the Kryptonite website shortly after purchase to be eligible for this coverage.

The sliding dust cover is designed to stay shut when the lock is not in use, protecting the internal cylinder from dirt, road grime, and moisture. While it is a simple mechanism, it is effective at preventing the keyway from jamming over time, especially if you ride in wet or dusty conditions.
