"This is an awesome bike lock and a great deal when you compare features and benefits with other bike locks on the market!"
"After having our bike room broke in to I wanted something heavy duty and this fits the criteria."
"Tremendous bike lock compared to my previous one (Masterlock U-Lock)."
"I've tried to mount other locks and they always end up interfering with one of my other accessories (cup holders, usually)."
"I found the mounting flexible enough to mount in a limited section of my upright tubing and still fit without conflicting with the pedal crank. I also like the large enough locking dimensions so easy to lock without the cable to a post or railing."
"Keep in mind the U-lock is somewhat short so when you lock up your bike frame, your bike must be placed very close to the bar in which you're locking it up to."
"I would have liked this lock and cable to put up a bit more resistance."

I hang the lock from a bracket on the handlebars that is for a front basket and the weight of the lock is sufficient to keep it from moving unless you go over a very large bump in the road. If you don't have a convinient place to carry the lock on your bicycle and don't mind a shorter length U-lock, the Kryptonite New York Standard Bicycle U-Lock with Bracket ( 4-Inch x 8-Inch) might be a better choice since it basically a shorter (4" x 8") and a bit lighter (3.9lbs) version of the New York LS U-Lock, with the same 16mm shackle and includes a bracket to mount the lock on your bike."
"I can easily lock up two bikes with this lock, and feel the security of a Kryptonite lock."
"However, when I tried it on my new bike, a Biria Citybike C700, I was sad to find out that the mouth of the lock isn't wide enough to go through both the frame AND rear wheel."
"First, the lock will turn 90 degrees even if the key is not seated, then it gets jammed."
"Kryptonite NY U-lock is too heavy to carry, and surprised at this price it does not come with any mount or holder. My shackle came with 2 deep cuts through the vinyl cover which do not compromise the strength or integrity of the U-lock. and I will keep greased and taped over to prevent rust."
"I bought it as a heavy duty lock that will deter theft but I found a few bikes in the city that were secured with a similar lock stripped of components."

"This is the chain to go with if you've ever had a theft attempt on your bike, or are smart enough to prevent it. It's 11/12 on their security scale and offers the highest level of reimbursement they will pay: $3500 for your bike if the lock is cut. This chain comes in at about 6 pounds, which is the highest reasonable weight I'll carry on my bike. Ok, so the noose design as you'd imagine turns this 2.25' (not 2.5' like the title says, not sure why they advertise that) and essentially gives you as much chain length from your bike to bike rack as a 4 foot chain would. A regular 4' chain would have to wrap in a circle and you'd connect both ends, so your bike could only really be 2' away from the rack. This chain ALSO gives you 2' between you and the rack with you looping or "noosing" it around the rack, thread it through ur back tire (always) and lock the chain to your seat tube or down tube."
"I originally bought the largest chain because I park my bike in downtown Manhattan, but I found that one to be *far* too large and weighty for commuting."
"This lock is excellent. It is a little on the heavy side, but it's worth it for a little extra peace of mind."
