Kryptonite New York Standard Bike U-Lock, Heavy Duty Anti-Theft, 16mm Shackle with Mounting Bracket and Keys, Ultimate Security for Bicycles E-Bikes and Scooters.

This is the most Kryptonite of Kryptonite locks, thick, strong, difficult to pick or cut through. Not impossible to defeat, used correctly, but about the best you'll get. Also, because of that: very heavy. What I don't like is the frame mount. No matter how it's mounted or adjusted, the mount (& lock) slides and pivots, often into the way of your pedaling, and with the size of the lock and the way the lock fits into the mount makes it difficult to impossible to mount out of the way (e.g., in the seat/cross/down post triangle).

Super sturdy lock. Feels premium and givems me piece of mind

This lock has been great. Recently, thieves cut through my e-bike and left my lock on the pole it was attached to. Until I get another bike it's useless, but at least I know the thieves found the lock intimidating. Wish I still had my e-bike.

No security system is 100% protective but this U lock combined with a heavy chain it a good deterrent. I was doubtful about spending more that 100 dollars on a lock for my bike, but it is worth it. With this lock I can use my bike for commuting and grocery shopping with relative and reasonable confidence that my bike will still be there when I return for it. Do be aware that the U loop does not fit all bike rack stations, depending on where you want to loop it around your bike. There are different sizes of U Locks & if you know you are commuting to a location with a chunky pole check the dimensions before you buy. Kryptonite's Anti-theft program might make this purchase worth it if you have a more pricey bike that costs 1,000 to 5,000 dollars, as one of kryptonite's programs will reimburse a loss depending on the value of your bike, if you register with them properly, should someone steal your bike by getting through their higher rated bike locks.

Stout lock. Let's be honest, "locks are for honest people". If a criminal really wants to use a battery powered angle grinder or the like, they are going to get through whatever you have. Unless you want to lug around a big steel and titanium cage with multiple layers. But probably still with that. The lock has been a good balance of portable and solid for a deterrent. If you're focusing on "not being faster than the bear but being faster than the other hunter" -- well, look no further thank this Kryptonite U Lock. we own 2, this one is the more secure one and while we'd recommend both, this model was what our son uses at school. just remember to park your bike in a well lit and frequented area and ideally... next to a few bikes that are nicer and less secure. don't let that bear eat your bike.

Well, it's a Kryptonite U lock, so much better than any cable lock, (don't even waste your money on those if your bike has any value at all. You might as well hang a sign, "STEAL THIS BIKE!") If anything, use a heavy chain at the very least. The stronger "FAHGETTABOUDIT" version is just too impractical because it's so short. I want to be able to just slip this on when I park, not figit with trying to work it into a tight spot and maybe scratch the paint. It is ironic that the LIGHTEST bikes cost more, so we need a HEAVIER lock to secure them, and this monster lock is not light by any means. There's some misinformation about the "Protection" offer. It doesn't say you HAVE to have insurance (as some have said), but it looks like you DO need to register your Bike (and Lock) ahead of time. From their website: "Remember this is an OPTIONAL offer and you MUST register to participate in the Program." You also have to notify the police within 72 hours, and Kryptonite within 7 days. Probably the only sticky point is they want a pic of the broken lock or may even want to see it in person. A thief might just take the lock with him to prevent fingerprint ID. I've seen some complaints about it being hard to unlock after using it for awhile. I'm wondering if that's from thieves who tried to pick the lock but failed. They might have damaged the pins, trying to ram screwdrivers or whatever into it. I debated about buying two lesser locks for the same price as this one. Seems having two locks is preferrable, although no lock is completely theft-proof. Any lock can be defeated given enough time and opportunity, like leaving your bike outside overnight. I might eventually buy a 2nd Kryptonite down the road for my $2800 Trek Domane, maybe the "Lite" version to compliment this one.

Sturdy and easy to lock

I bought this to lock up my new ebike. I've used (cheaper, lower quality) Kryptonite U-locks on my acoustic bike in Boston for 13 years before this. I splurged on what I thought was the heaviest, priciest, most durable lock out there. It was just barely enough. Less than 6 months after I bought the bike, I woke up to a text message saying someone tried, and failed, to steal it. I ran outside to find the lock as you see it here. The thief had found a working electrical outlet at the park near my bike, brought a 50 foot extension cord and a corded angle grinder, and cut one side of this lock in under 60 seconds. I know this because my neighbor caught it on his doorbell cam, timestamped at 1:50 AM. Then another neighbor yelled at the thief, who ran away before they could finish cutting the other side of the lock. Had the neighbor not yelled, and had the lock not required 2 cuts, I wouldn't have a bike anymore. If you have a nice looking ebike in an urban area, consider this the bare minimum. I've upgraded to the New York Diamond Standard since then, and it seems to be holding up, which for the $300+ price tag, it bloody well should.

Conforme à la description. Du bon matériel

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.

Recently bought an expensive bike and with this luck i can finally feel at peace to leave my bike alone for around 15 minutes to do my groceries, but the mount that you put on the bike already came loose within 5 days and is basically useless.
