I was appalled but I took it in stride. I had just walked into amazon fresh in pasadena to get some items, not realizing someone was ruining my bike outside. I came out and tried to unlock it and it was jammed! The criminal sat on a bus bench and didnt even leave!! altho, he covered his face w/ his hands! I had to go back into amazon fresh and ask for assistant. A guy in the back got BOLT CUTTERS. He just happened to have them, because he said "when employees leave they lock the storages". He broke through my severely damaged ulock offbrand that I bought here on amazon. I then realized the creep had hurt my front wheel so badly i had to drag it all the way home! I literally had to walk my bike home. I went back in and asked him to help me to make my front tire move!Thanks to the guy at the Amazon Fresh in Pasadena who was very helpful. You should tho have a bike area to lock your bike CLEARLY IN FRONT OF THE STORE and not off way to the side. This probably would have NEVER HAPPENED if you knew where to places to lock your bike.Which brings me to this lock. It took 100.00 to repair my bike and get this lock, and its nice and long, easy to turn once you figure it out and very sturdy.I will never lock my bike by far from a store. I will never lock my bike by a bus bench. I will never be out after 10 and LEAVE my bike locked where criminal element surely can exist. ### ⭐⭐⭐⭐⭐ great lock is it worth the price *by on Reviewed in the United States January 7, 2026* they work great and make my bikes feel much more sacure...wish the shackle was just a lil bit longer or the locking worked a lil more smoothly as i have issues making sure the key is in the right position to allow lowing and unlocking the shackle.. but that is the price of secuirty perhaps since the lock is new the key is catching ### ⭐⭐⭐⭐ Better than a cable *by on Reviewed in the United States August 14, 2025* Kryptonite locks have always been quality, and they work well very sturdy. But the Thievin has clicked up to a higher level these days and thieves are getting more tricky so good luck. ## Frequently Bought Together - Kryptonite Kryptolok Standard Bike U-Lock, Heavy Duty Anti-Theft Bicycle U Lock, 12.7mm Shackle with Mounting Bracket and Keys, High Security Lock for Bicycles Scooters,Black - Kryptonite Keeper 785 Bike Chain Lock, 2.8 Feet Long Heavy Duty Anti-Theft Bicycle Chain Lock with Keys for Bike, Motorcycle, Scooter, Bicycle, Door, Gate, Fence - Apple AirTag --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/46512184-kryptonite-kryptolok-standard-bike-u-lock-heavy-duty-anti-theft](https://www.desertcart.us/products/46512184-kryptonite-kryptolok-standard-bike-u-lock-heavy-duty-anti-theft) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-07-04*
