Review: Feels secure and reliable, worth the extra weight - This is a seriously solid lock that gives you a real sense of security. The U lock alone is thick, heavy, and feels virtually tamper-proof. The included flex cable is a great addition, giving you more options to loop through your wheels or around awkward railings or posts. I’ve used it to lock both my frame and rear wheel with the U lock and then looped the cable through the front wheel. That versatility makes a big difference in urban areas where secure anchor points aren’t always ideal. While it is heavier than cheaper alternatives, the added weight feels justified by the protection it offers. I’d much rather carry a little extra bulk than come back to a missing bike. The lock mechanism is smooth, and the key turns easily without sticking, which I appreciate after past frustrations with cheaper locks. Pros: Heavy-duty and high quality Flexible locking options with included cable Smooth key operation Cons: A bit bulky for smaller backpacks It might be overkill for low-crime areas Review: Solid and Reliable Lock — Worth the Price - My husband said it Feels really sturdy and well built. The lock mechanism is smooth and doesn’t jam like cheaper ones he's used. It’s got a good weight to it without being bulky to carry. It gives him confidence leaving his bike locked up. A proper bit of kit if you want security and peace of mind. ## Features - Complete solution with U-lock and cable - Key Safe Program - Rated 6/10 on Kryptonite’s security scale - Optional ATPO - £1,000 - Sold Secure Bicycle Gold certified ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06XCLTVPQ | | Best Sellers Rank | 3,319 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 6 in Cycling U-Locks | | Brand | Kryptonite | | Colour | Black/Silver | | Control Method | Touch | | Controller Type | Hand Control | | Customer Reviews | 4.5 out of 5 stars 5,957 Reviews | | Finish | Vinyl | | Global Trade Identification Number | 00720018001966 | | Included Components | Locks | | Item Dimensions | 10.2 x 10.2 x 22.9 centimetres | | Item Type Name | Standard U-lock With 4 Foot Kryptoflex Cable - 2017 Edition | | Item Weight | 2.91 Pounds | | Item dimensions L x W x H | 10.2 x 10.2 x 22.9 centimetres | | Lock Type | Keyed Lock | | Lock type | Keyed Lock | | Manufacturer | MDSL4 | | Manufacturer Warranty Description | 2 years. | | Material | Alloy Steel | | Model Name | KryptoLok | | Model Number | 001966 KryptoLok STD & KryptoFlex 410 | | Number of Pieces | 1 | | Part Number | 1966 | | Recommended Uses For Product | Security | | Recommended uses for product | Security | | Shape | U Shape | | Smart Home Compatibility | Not Smart Home Compatible | | Special Features | Anti-Theft, Heavy Duty | | Special feature | Anti-Theft , Heavy Duty | | Style | KryptoLok | | UPC | 720018001966 | | Unit Count | 1 unité | ## Product Details - **Brand:** Kryptonite - **Item dimensions L x W x H:** 10.2 x 10.2 x 22.9 centimetres - **Lock type:** Keyed Lock - **Material:** Alloy Steel - **Special feature:** Anti-Theft, Heavy Duty ## Images ![Kryptolok Standard Bicycle U-Lock w/4-foot Flex Cable - Image 1](https://m.media-amazon.com/images/I/81Qvx8aOCAL.jpg) ## Available Options This product comes in different **Configuration, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Feels secure and reliable, worth the extra weight *by M***Y on 14 July 2025* This is a seriously solid lock that gives you a real sense of security.

A proper bit of kit if you want security and peace of mind. ### ⭐⭐⭐⭐ Good lock but couldn't register for the free replacement key service. So, 4 not 5 stars. *by N***L on 10 April 2026* Great lock and cable, but I couldn't get the online registration for free replacement keys (in the event of loss) to accept the keys' number. Although I couldn't fit it in any of the recommended places (due to my drinks bottle) I am pleased with where I've managed to locate it on the front wheel fork. ## Frequently Bought Together - Kryptonite Kryptolok Standard Bike U-Lock with Cable, Heavy Duty Anti-Theft Bicycle U Lock, 12.7mm Shackle and 10mm x 4ft Length Security Cable with Mounting Bracket and Keys - Ascher Ultra Bright USB Rechargeable Bike Light Set, Powerful Bicycle Front Headlight and Back Taillight, 4 Light Modes, Easy to Install for Men Women Kids Road Mountain Cycling Black - Zewdov Bike Lights for Night Riding, USB Rechargeable Bike Lights Front and Back, Waterproof IP65 Bicycle Light, 4+6 Modes Bike Headlight and Tail Light Set,1.5 Hrs Fast Charging, Easy to Install --- ## 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.tn/products/50673365-kryptolok-standard-bicycle-u-lock-w-4-foot-flex-cable](https://www.desertcart.tn/products/50673365-kryptolok-standard-bicycle-u-lock-w-4-foot-flex-cable) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-05*
