This is a brand-new, unused Kryptonite Kryptolok U-Lock, built for reliable, heavy-duty protection for your bicycle, e-bike, or scooter. I purchased it and then missed the return window, so I never got the chance to send it back. It’s been sitting unused in my closet ever since, and I decided it would be better to sell it than let it sit around. The lock has never been used, and I haven’t even removed the keys or zip ties from the packaging.

The Kryptolok features a 12.7mm hardened performance steel shackle that offers excellent resistance against cutting and leverage attacks. Its patented double deadbolt design provides extra protection against twist attacks, while the high-security disc-style cylinder helps prevent picking and drilling.

The interior locking dimensions are approximately 4 in. x 11.5 in, with a total weight of about 2.9 lbs. The lock includes two stainless steel ergonomic keys, designed for smooth use and long-term durability.

Rated Sold Secure Gold, this Kryptolok meets one of the highest industry standards for bicycle security. It’s perfect for bikes, e-bikes, scooters, gates, or outdoor gear — anywhere you need strong, dependable protection.
