KryptoniteNew York Long Shackle Bike U-Lock, Heavy Duty Anti-Theft Security Bicycle Lock Sold Secure Gold, 16mm Long Shackle with Keys, Ultimate Security Lock for Bicycles E-Bikes Scooters

Super strong although heavy to carry in your pannier but unfortunately top security is needed when you have an e bike!

Great lock and really easier to use. Is rather heavy and doesn’t fit most bike lock travel holders. Most secure bike like I’ve ever used!

From the description I thought it was 26cm in total, and it's only internally. In total is 33cm, I found it a little big. I wouldn't have bought it knowing it was 33cm. There is no way to fix it on the bike. You have to figure out the way. But it's very strong.

So this is undoubtedly a great lock, but nothing is angle grinder proof! So this is at the maximum of what I'd spend for a U-lock, as anymore money, is just down the drain I feel, especially if buy the really expensive chains, as once they have grinded through them, you are just gifting the thief a chain as well as your bike.The only thing to look out for with this U-lock is that it's a bit narrower than some other comparative U-locks, so may not fit around some gates that are a bit thicker, if using to secure gates at your home.

Strongly Recommend

Amazing product, for safety and piece of mind

I’ve been using this lock for about 2 years now, and today it finally happened - some thieves broke into my bike storage and went to work on it.As shown in the picture, they managed to cut through one arm, however this was insufficient to let them pull it out, and so they started trying to cut through the other side and at the top. It must have taken them too long in the end, or maybe they couldn’t get a good angle, but either way, they left it!I’m thankful I invested in this lock as it did save my bike - another bike in the same storage using a cheaper lock got stolen. So while no lock is 100% indestructible, it does seem like this one presented enough of a challenge for them to give up on it.

The Lock looks big and solid but never came with Transit Flex Frame-U transportation system which was advertised as including with the lock."Includes Transit Flex Frame-U transportation system which allows for versatile carrying"
