Review: Great U-Lock and integral part of a locking system. - Impressive looking lock that does not weigh as much as other locks, but still provides excellent security for my bicycle. I use this to lock up my Bianchi Volpe and can sometimes also lock up another bike next to mine. I am not a fan of the small metal fitting that is supposed to be used with a plastic fitting to hold the lock on your bike, so I taped the metal to keep it from scratching my paint finish. I use this lock with multiple bikes, so I don't want to buy plastic fittings for each bike so taping it makes sense. The keyway is in the center of the orange part and the key goes deep into the crossmember. The keyway has a handy plastic cover to keep the keyway clean and it works well and does not get in the way. And one of the keys has a built in flashlight with just enough juice to help you unlock the lock. I feel very confident when I use this lock. Note that it has the flat key, not the old round one that could be picked easily. This lock will not survive an angle-grinder, but then again, nothing will survive such an attack. I use this lock as my primary way to prevent theft and I add an Abus frame lock with a hardened steel chain, figuring that few crooks have experience with a frame lock in the US, so if an angle grinder is used, it will cut through the Kryptonite and the Abus chain, but the frame lock would take multiple cuts, plus a lot of fussing, to defeat the frame lock which is around the rear wheel. Plus, all of this looks impressive and hopefully a thief will bypass my bike as being too much work. Note that many people use a cable lock to tie up the front wheel to the U-lock, but I prefer a hardened steel chain as a pair of pliers will not cut through the U-lock nor the chain. Review: Great improvement for Kryptonite - The new centered key mechanism and double-bolt design is really excellent and big improvement over the previous designs that Kryptonite used to use. The key is more complicated, the keyhole is small and has a built-in cover. The key turns very smoothly on mine. The double bolt is a great feature because the key controls bolts on *both* sides of the lock requiring a thief to cut both sides of the lock before releasing the bike. This is a substantial lock. That also means that it is *heavy*, so it may not work great if you are looking for a lock to carry around everywhere. I use this to lock up my commuter bike outside overnight, and the lock gets left on the post 24 hours a day. So far has worked out. Crossing my fingers. The common wisdom is that it is better to use as small a lock as possible to reduce the possibility of using a crowbar to get leverage on the lock. But sometimes you need a big lock, and that's when I use this guy. It works well on my hybrid to thread it through both seat stays, the wheel rim, and a sizable post. This leaves very little space and there is *always* a less securely locked bike close at hand. All locks can be broken, so the game is to lock it up enough so that most thieves would rather spend their time on other bikes (or, hopefully, doing something productive for society). It's true that the mounting bracket is a bit of nonsense. It doesn't work anywhere on my bike, so when I do carry this lock around, it has to go in a bag. ## Features - 14mm hardened MAX-PERFORMANCE STEEL SHACKLE resists bolt cutters and leverage attacks - Patented*, HARDENED OVAL CROSSBAR design is stronger than typical round tube - Hardened DOUBLE DEADBOLT DESIGN gives additional protection against twist attacks - HIGH SECURITY DISC-STYLE CYLINDER - Includes NEW TRANSIT FLEXFRAME-U transportation system which allows for versatile carrying - Protective vinyl coating - SLIDING DUSTCOVER protects and extends cylinder life - 3 STAINLESS STEEL KEYS – one lighted with high intensity LED BULB 7 REPLACEABLE BATTERY - Key Safe Program - Product dimensions: 4” x 9” (10.2cm x 22.9cm) - 14mm hardened MAX-Performance steel shackle resists bolt cutters and leverage attacks - Patented*, hardened oval crossbar design is stronger than typical round tube ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005YPK99I | | Additional Features | Key Lock | | Best Sellers Rank | #328,640 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #167 in Bike U-Locks | | Brand | Kryptonite | | Brand Name | Kryptonite | | Color | Black, Orange | | Control Method | App | | Controller Type | Hand Control | | Customer Reviews | 4.4 out of 5 stars 980 Reviews | | Global Trade Identification Number | 00720018001010 | | Included Components | Transit FlexFrame-U transportation system, 3 stainless steel keys (one with an LED bulb and replaceable battery), sliding dustcover | | Item Dimensions | 4.02 x 0.55 x 9.02 inches | | Item Weight | 1 Pounds | | Item dimensions L x W x H | 4.02 x 0.55 x 9.02 inches | | Lock Type | Key Lock | | Manufacturer | Kryptonite | | Manufacturer Part Number | 001010 | | Material | Alloy Steel , Stainless Steel | | Material Type | Alloy Steel, Stainless Steel | | Model Name | Evolution Series 4 | | Model Number | 152069 | | Number of Pieces | 4 | | Recommended Uses For Product | Security | | Shape | Oval, Round | | Special Feature | Key Lock | | Style Name | Original | | UPC | 757183194568 182682055889 787766678390 787766664904 706084269233 787766665642 720018001010 | ## Product Details - **Brand:** Kryptonite - **Item dimensions L x W x H:** 4.02 x 0.55 x 9.02 inches - **Lock Type:** Key Lock - **Material:** Alloy Steel, Stainless Steel - **Special Feature:** Key Lock ## Images ![Kryptonite Evolution Series 4 Standard Heavy Duty Bicycle U Lock Bike Lock (4-Inch x 9-Inch) - Image 1](https://m.media-amazon.com/images/I/61KC5vD0uzL.jpg) ![Kryptonite Evolution Series 4 Standard Heavy Duty Bicycle U Lock Bike Lock (4-Inch x 9-Inch) - Image 2](https://m.media-amazon.com/images/I/910+RAXu4AL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great U-Lock and integral part of a locking system. *by W***N on September 4, 2014* Impressive looking lock that does not weigh as much as other locks, but still provides excellent security for my bicycle.

The lock itself feels sturdy, and I'm not noticing any peeling or issues with the outer coating so far. The numerous included keys are nice, and this one's definitely much longer than many other U-Locks, which makes it much easier to lock up my bike than before. I only have one problem, and it's with the installation of the holder for the lock itself. You probably won't be able to fit this on an E-Bike with a thicker frame. The strap they include with the mount simply isn't long enough for anything larger than the small tube frame you'll get on a standard non-E-Bike, so you'll need your own replacement strap, or have to mount it on the side of your bike's back frame/basket if it has one. --- ## 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.ae/products/1430776-kryptonite-evolution-series-4-standard-heavy-duty-bicycle-u-lock](https://www.desertcart.ae/products/1430776-kryptonite-evolution-series-4-standard-heavy-duty-bicycle-u-lock) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-05-31*
