Peace of mind Having this lock just gives me extra peace of mind. You can definitely feel the weight of the chain so you know it's not just flimsy metal. Like that it has the cover so as to not scratch up the wheel. December 21, 2014
Hefty lock Got this for my 1974 Honda CB360. I live in a sketchy neighborhood and was worried about someone lifting (literally) my baby. This lock will help deter thieves. September 15, 2014
Sturdy chain that offers piece of mind... This chain does exactly what it is supposed to do which is offer me a piece of mind. Any chain can be cut with the right equipment but I feel Kryptonite products make thieves at least think twice, or look for an easier target. This chain could be thicker - Kryptonite sells such locks - but I settled on this model and have been impressed. I really like the durable nylon coating that protects the chain and your wheel. The best feature for me is the integrated lock - it saves time, provides a bit more theft resistance, and functions smoothly. I should mention that I do park in a garage and use this chain and a Xena disk alarm but would still feel confident leaving my bike on the street overnight with a bike cover. I'm pretty sure I have the longer chain, which I recommend - it can be a real hassle/danger/time waster pulling the bike so close to a stationary object. August 6, 2014
Powerfull Strong sturdy easy lock mechanism and stylish chain I love the durability and the feel of this chain July 28, 2014
worth it Great chain. Feels hefty. It stays at my apartment. Wish I got the longer one as this one is barely long enough to get it around one of the polls. Would highly recommend. Works on my 2014 Grom. September 23, 2013
A Simple Chain & Lock This chain doesn't feel unbreakable, but it does its job on making my bike a bit less attractive to thieves. The key looks fancy and I cannot imagine how somebody could ever pick it. I use this chain in combination with a Xena disc lock alarm and feel pretty confident that my bike will not get stolen.

Great for extra protection I park my bike in an underground parking structure, so it's relatively safe but as an additional precaution I purchased this chain lock. It's very easy to use, and appears to be very durable. It's heavy enough to withstand a high amount of force but even the 60" 8.10 lbs chain is still light enough to carry in a backpack.

great lock, thick key, feel safer leaving my bike I love this lock compared to the last lock I owned. I've read tons of reviews on different locks and thought Kryptonite was the one of the best. The key is much thinker then other locks similar to this which makes it less prone to break off in the lock. also it is operates smooth when opening and closing. I use this one with my Bicycle and scooter. I feel better about leaving either of them when I lock it up. June 25, 2012
