Kryptonite Krypto Series 2 U-Lock

Yes, it is designed for urban environments. The 12.7mm hardened steel shackle and double deadbolt mechanism provide strong resistance against common theft attempts like prying and twisting.

The FlexFrame U-Bracket is adjustable and designed to fit most standard bicycle frames. However, if you have an unusually shaped or oversized frame, you may need to find a specific mounting point on your seat post or frame tubing.

The lock weighs 2.45 lbs. While you will notice the weight, it is considered a compact and manageable option for daily commuting, especially when secured to the frame rather than carried in a bag.

The lock comes with two keys. Kryptonite offers a key replacement program, so it is highly recommended that you register your key number with them immediately after purchase.

Yes, the lock features an integrated dust cover that shields the high-security disc-style cylinder from dirt, grit, and moisture, which helps prevent the mechanism from seizing up over time.

With internal dimensions of 3.25 x 7 inches, this lock is best suited for standard bike racks, parking meters, or thinner poles. It may be a tight fit or impossible to use on very thick street sign posts or large trees.
