These locks are easy to use, and while heavy and a little bulky, give a good feeling of security. The longer shackle model of the lock can be a little bit harder to store on a bike however, especially if you use bottle cages. The mounting system for storage has been upgraded from previous lock models. Previous Kryptonite locks I have used included a plastic clip that was hard to attach and detach from the lock without breaking, not to mention a nightmare to install on the bike. With the new mounting kit, the plastic components are a little bit larger, but much more robust. The release mechanism feels less likely to snap, and the installation of the kit includes the use of a webbed strap and metal buckle (the bike is protected by a rubber insert) that firmly attach to the bike frame. Be cautious, however, that bike frames with non-round frame members can be a little hard to attach to. Review: great lock its big but works if you dont want to take off your front tire on a mountain bike with a shock every time! - WOW this specific model of kryptonite evolution series 4 LS is amazing. the reason i went with this specific model is first its rated 8/10 for toughness to steal and second the LS version is long shackle. which really helps me with my mountain bike reason being i dont have to take off the front tire the shackle is long enough to fit through my tire frame and bike rack. now this doesnt fit on my bike with the bracket provided with the lock this is due to the fact that the lock slides onto the bracket and if the bracket was placed farther up there isnt enough room in my bike frame. the lock does fit in my frame if i was to bungie cord it or find a different way to secure the lock. i dont mind this at all and was expecting it do to the size of the shackle. i have another kryptonite ulock coming for just the back tire to the frame i would rather carry a extra lock then take my tire off every time plus two locks are better then one. also if kryptonite made it so the silver mounting bracket could slide up and down that would solve the problem of the bike bracket. ## 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 & REPLACEABLE BATTERY - Key Safe Program - Product dimensions: 4” x 11.5” (10.2cm x 29.2cm) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005YPK9N4 | | Additional Features | MAX-PERFORMANCE STEEL SHACKLE | | Best Sellers Rank | #29,958 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #33 in Bike U-Locks | | Brand | Kryptonite | | Brand Name | Kryptonite | | Color | Black, Orange | | Control Method | Remote | | Controller Type | Hand Control | | Customer Reviews | 4.3 out of 5 stars 311 Reviews | | Finish Types | Protective vinyl coating | | Global Trade Identification Number | 00720018001027 | | Included Components | U Lock | | Item Dimensions | 14.4 x 6.8 x 2.1 inches | | Item Weight | 16 ounces | | Item dimensions L x W x H | 14.4 x 6.8 x 2.1 inches | | Lock Type | Keyed | | Manufacturer | Kryptonite | | Manufacturer Part Number | 001027 | | Material | Alloy Steel, Stainless Steel, Vinyl | | Material Type | Alloy Steel, Stainless Steel, Vinyl | | Model Name | Evolution Series 4 U-Lock | | Model Number | 3500330 | | Number of Items | 1 | | Number of Packs | 1 | | Number of Pieces | 1 | | Recommended Uses For Product | Bike Lock, Cycling | | Shape | Oval, Round | | Special Feature | MAX-PERFORMANCE STEEL SHACKLE | | Style Name | Original | | UPC | 706084269141 720018001027 | | Unit Count | 1 Count | ## Product Details - **Brand:** Kryptonite - **Item dimensions L x W x H:** 14.4 x 6.8 x 2.1 inches - **Lock Type:** Keyed - **Material:** Alloy Steel, Stainless Steel, Vinyl - **Special Feature:** MAX-PERFORMANCE STEEL SHACKLE ## Images ![Evolution Series-4 LS Heavy Duty Bicycle U Lock Bike Lock with Transit FlexFrame Bracket (4-Inch x 11.5-Inch) - Image 1](https://m.media-amazon.com/images/I/61x9fjSvkrL.jpg) ## Available Options This product comes in different **Pattern, Style** options. ## Questions & Answers **Q: Can i mount this to the screw holes for the water bottle mount known as bosses or braze-ons?** A: It’s a sturdy nylon strap/clamp.
