  • Glad I got the long-shackled option
Size: 4" x 10.25" 16mm Style: New-U 2017
Heavy but that's what you pay for toughness. Good keylock (3 keys). No easy frame mount so I carry it in my basket wrapped in a heavy bag and a bungee net. So glad I got the long shackle option!

  • This Lock Saved My Ebike!!!
Size: 4" x 10.25" 16mm Style: New-U 2017
Back in 2021 I decided to upgrade my bicycle locks. One because I purchased an Ebike and 2 I live in at the beach, high bike thefts. Due to storage constraints, my bike is locked in the front yard of my home. The other night these two yahoos tried to cut the lock off. Extra large bolt cutters! First the bigger guy, than they tried each holding on to one side and it slipped and smacked the big guy. Look of defeat as the walked out of my yard was priceless. UPGRADE AND NEVER WORRY AGAIN! After posting this on my Nextdoor I was bombarded with request of the exact lock. These guys get a perfect 5 star review on this lock!! ... show more

  • Serious About Locking
Size: 4" x 10.25" 16mm Style: New-U 2017
This thing is a massive lock and heavy one at that. I planned to lock my Segway eScooter with it. I think you could use it to lock a wheel on a car. Seriously, this thing is one of the most secured built locks I have seen for a bicycle, scooter, and even motorcycle. You could use it as protection as well. It would knock someone silly if some tried approaching you and get in your space. It does not come with anything to carry it. I went on Amazon and found Velcro/Rubber fasteners to hold it on the stem of my eScooter. Works awesome! Highly recommended. ... show more

  • Go with quality
Size: 4" x 10.25" 16mm Style: New-U 2017
Its Big, its heavy but you have piece of mind knowing its a reliable lock. Best to have something along with this as I have the 4 foot kryptonite cable just to make sure. The long shackle gives you some extra reach if you need it

  • No lighted key.
Size: 4" x 10.25" 16mm Style: New-U 2017
I purchased the New York lock because of its high quality. Also, the lighted key grabbed my attention. I figured it would come in handy in the dark. When I received the lock, I discovered that it had three keys but no lighted key. I wanted to contacted the company through their email request page and make a complaint. They had a section that indicated that they no longer included the lighted key and that it was discontinued in 2024. All of the information that I obtained regarding the lighted key was in February, 2026. Before submitting the complaint, it was requested that I take pictures and send them along with my complaint. Well, I mainly work from my computer, not my phone. To take pictures from my phone, down load them to my computer, make sure they were in Jepg, png, or pdf, seemed to be a bit too much just to submit a complaint. The problem that I have is that Kryptonite stopped inclulding the lighted key in 2024. I read the information that the lighted key was part of the package in February, 2026. I feel that two (2) years is more than enough time to remove the lighted key information from their advertising. It was extremely misleading. I was tempted to return the lock and purchase one from another company, but no other lock could compare to Kryptonite. It would help customers if Kryptonite and Amazon removed that misleading and incorrect information from the New York lock advertisement. The only reason I gave it four stars was because of the incorrect information regarding the lighted key. ... show more

  • Best Bike Lock for the Money
Size: 4" x 10.25" 16mm Style: New-U 2017
The Krytonite New York bike lock is probably the best lock out there for the money. Yes, there’s a YouTube Video of a guy cracking in in less than two minutes. There’s also people that can crack $100,000 safes. The goal is not to eliminate risk; that’s impossible. The goal is to find the balance of risk reduction with the cost/effort required while considering what your trying to protect. For a $20 knock around bike, pick up $5 lock at target. For a $$2,000 roadie, this lock is appropriate. UPDATE: Had a brief moment of buyers remorse when I realized the lock’s size made impossible to attach to my bike and even heavy to carry in back back. Bought a smaller Kryptonite lock for riding and use the monster as a second lock at home. I also use it for temporarily securing other items on ground floor condo patio. ... show more
