KryptoniteNew York Standard Lock with Flex Frame U-Bracket - Yellow, Standard Shackle

This has not been attacked, but appears to be really strong, well made and thought through.It replaces a more expensive Abbus Granit lock that after many years, the key got sticky and broke. This seems to me to be an upgrade in terms of material, build and quality, it has a small plastic sliding "gate"to keep dirt out of the keyhole (which was the led to the eventual demise of my Abbus).It comes with three keys (reassuring on such a tough lock), two of them are ultra small and lite in weight the third has a lED light built in that works well, although I do not use it as I like to keep things minimal and this key is a bit more bulky. Size wise, the lock is perfect, not too long or too narrow - it fits over the rim and tyre of a front wheel of a motorbike or would provide close protection for a bicycle frame against a railing - meaning lever style attacks would be difficult.I like the holder attachment, when used correctly, it works very well. I might buy a second lock for permanent placement and (the silver holder part on the U-lock can be removed which I also like).In a perfect world, I would love to be able to buy two locks with same key - so the extra colour option is helpful for identification if two are used.

This lock screams 'have a go if you think you're hard enough!!'. Premium look and feel. Weighty and really sturdy. The lock is able to be concealed by the sliding cover and is easy to lock/unlock. The key has a nice little light on it too. There is no way this 'bad boy' is coming off once attached - unless with a heavy duty tool and even then it will take some doing. Provides some reassurance that it will likely deter any 'would-be' opportunist. I couple it with a heavy duty chain lock too. Would definitely recommend.

Highly recommended. This is my second lock of the exact same model and I have absolute faith in it. This lock has kept my bike safe for 7 years and is still going strong - the only reason I bought another one is because if fear the price going up in the coming months. This lock has been tried multiple times by thieves and has stopped them on every occasion. The key guard was smashed off and the D loop has been attacked over and over, but only the rubber coating has given way. This lock is heavy, but it’s worth it’s weight in gold for how it has served me.

I bought the Kryptonite New York Lock because I wanted a strong lock for my motorbike. When I received it, I could see the quality was good. The lock feels heavy and solid, and the yellow colour is easy to see, which I think helps stop thieves before they try anything. The standard shackle size works well for locking my bike to metal rails. The flex frame holder is useful too, so I can carry the lock on my bike when I ride.But to be honest, I feel this lock is too expensive. Yes, the build quality is strong, and it feels secure, but the price is much higher than I expected for a bike lock. I know it’s a good brand and gives good protection, but for me, the high price makes it hard to recommend to everyone.Using the lock is easy. The keys turn smoothly and the shackle opens and closes without problems. I feel safe leaving my bike locked with it, which is the most important thing.

Great sturdy lock, really pleased with it. I read previous reviews so was aware that there’s a rattle - the rattle comes from the lock itself, not the mount. The mount is really sturdy and easy click on, click off. The rattle itself is noticeable but I tuned out from it really quickly and often have music on quietly which helps. Luckily this fits (just) within the frame of my bike and with it resting under the top bar it doesn’t rattle, but I imagine on smaller frames it would be an issue. I’m really pleased, and it definitely feels like a sturdy lock, not worried about leaving my bike with this lock, compared to many others tried in the past.

This seems to be the minimum recommended thickness for resisting bolt cutters. An angle grinder will get through this with enough time. If you really care about your bicycle then I would suggest also buying the next thickness up for your frame and the next thickness down for your front wheel, using this lock to secure your back wheel to your frame or to the same post that your frame is already secured.

Very good lock, the mount is useless though. It's a big lock so it doesn't mount anywhere properly on my bike. I also tightened up the mount on the lock and it still didn't mount properly. If there is a large opening in the centre of your frame, you would probably be able to mount it fine, but not the case with my mountain bike. The weight of the lock will just make it fall sideways, unless it's hanging. I just carry it hanging on my handlebars or in a backpack.But that doesn't take away from the great rating of this lock. I definitely feel assured that my bike will be safe with this lock. Its a very hefty lock and after reading/watching reviews, you aren't going to be able to break it without angle grinders. Definitely worth the money if you live/work in a big metro area.

This is an easy-to-use, high quality lock that you can feel confident will keep your bike secure. It's expensive but the quality is clear to see and a small price to pay for peace of mind, especially when commuting.The U-lock is very sturdy and slots smoothly together. The lock is very heavy, which makes it a bit less appealing if you're carrying in a backpack or similar, but it can also be fitted to the bike frame when not in use if preferred.The additional loop cable is long and easy to manoeuvre. It can be used to form loops around tyres and frame, allowing you to secure more points on the bike and increase the difficulty for opportunistic thieves; the loop ends then fit neatly through the U-lock to hold in place.The supplied lock key is fitted with a bright blue light to help lock/unlock in darker situations.All in all, very happy, great purchase that will last a long time.
