KryptoniteEvolution Mini-7 FlexFrame Lock with 4-Feet Kryptoflex Cable - Black/Orange

Rarely do I post reviews for products (on the basis that if something I've bought does what it's supposed to, I see no reason to declare it to be the best thing since sliced bread...). In this case, however, I feel it reasonable to share my experience.Having taken a short cycle holiday recently, we left our bikes locked for the night in a well-lit area outside of our hotel in a town centre and returned the next morning to find that some light-fingered toerag had decided to have a go at them during the night. Whether they'd not had enough time or strength I can't say but they were clearly foiled by the lock and cable. They've obviously attempted to twist the cable to breaking point with some sort of bar or lever as can be seen by the damage done to the cable. Whilst the cable needs to be replaced and there's damage to the paintwork on my bike and to the bracket on the lock itself, both bikes are still in our possession and we're very glad about it.The lock is still perfectly usable (as is the cable really although it's pretty mangled - 1 strand of cabling did give way) but decided to buy a second one rather than simply replace the cable (which is obviously the weaker of the 2 components). I've never used the bracket anyway (as many people have said, the fixing isn't the greatest so the lock always lives in one of our rack bags that sit on the top of the pannier racks) so the damage to this isn't an issue for us.I'm really pleased to be able to provide some solid evidence on the strength of the locks whilst still having our bikes - unsettling though the experience may have been. We simply took the view that the would-be thief left frustrated and we still had the bikes so didn't let it put a dampener on the holiday.Thanks Kryptonite - money well spent.

Trusting the Kryptonite brand was the right decision. I bought this in order to replace a very similar lock that was by a lower quality brand and can see and feel the differences hugely. Having this comparison emphasises the small details that make Kryptonite a superior, and therefore trusted, brand.- Small enough for bag, coat pocket and large back pocket on men's jeans but not mine!- Lighter than similar locks of this size from other brands- Key mechanism is smooth and secure- Sturdy and durable- VERY GOOD PRICE!- Fits a large bike (I have a very large men's bike and it fits, snugly, but it fits!)- I have not used the connection onto the frame as I tend to either put it in my bag or just wrap it around the frame depending on my journey.- Good bright colour and I think this adds as a deterrent to would-be-theives as the Kryptonite brand is known for their toughness- D-lock and cable lock combination** GOOD INFO** I was once left a note on my bike by the local police who had graded all of the bikes in the area on how well they were locked. The extra info stated that the most effective way of locking the bike is for the D-lock to be threaded through the frame and front tyre (front?! - 90% sure it's front as that's the wheel that's easier to remove) and the cable to be threaded through the back tyre and locked onto the D-lock. The straight part of the D-lock is to ideally be rested on the opposite side of the metal bike lock frame. The reasons for this are:- The straight part could be dislodged by a sledgehammer so having it against a non-stable surface such as the tyre makes this very difficult/impossible- Two different locks (ie, solid metal and cable) are to be used together as when it comes to law enforcement, if someone is caught carrying one tool such as bolt cutters (with no obvious reason such as their employment) then there is no real reason to suspect anything. However if someone is caught with two tools that can be used for 2 different types of lock for no obvious reason - this can show intent to steal a bike or other devious crimes and are more likely to be in trouble thus saving you from a potential bike thief! Maybe others have heard this and can corroborate?Either way, it is much safer to use two locks to secure your precious mode of transport.Highly Recommend! Very Good Egg :)

This is a medium strength D lock. At about 1.3kg, it is about the right weight to carry whilst out and about.It's easily large enough to put around a standard bike rack and one wheel. It just about covers both wheels and a standard bike post (if you take the front wheel off, obviously!). It's a bit too small for most lamposts.In terms of security, it is strong enough to withstand most bolt cutters but a sturdy pair of 42" bolt cutters would probably defeat it. I'd expect it to last only a few seconds against an angle grinder though (a type of attack becoming more common in London, even in daylight). I would recommend this for medium risk areas but not high risk areas like central London, especially if your bike is worth more than £200. For the price it's as good as you'll get but for higher risk areas, you'll need a Sold Secure Gold rated lock.The biggest downside is the sub-standard bracket. It secures with a strap that relies on tension from the screw that holds the bracket to the frame. One poor quality screw is obviously not strong enough to secure a 1kg lock to a moving bike. Therefore the bracket came loose quickly and needed tensioning weekly, and before long the screw thread went, meaning the bracket needed replacing. There's no good reason they couldn't have used multiple screws and a buckle to secure the strap, it's incredibly sloppy design.So in summary if you want to carry this in your backpack - it's a great lock for the price. However if you want a lock to carry on your bike, don't bother with this one.
