Kryptonite KryptoLok Series 2 Integrated Chain Lock 4.2 5 11 11
Very secure, but lock jams I recently, accidentally locked my friend's bike to mine in front of our gym (Sorry Pasquale!!!). I realize there are other methods of breaking locks, but the KryptoLok laughed off some pretty strong guys with bold cutters. One thing -- after about three months the mechanism became VERY stubborn, making locking/unlocking my ride a several minute ordeal on a bad day. January 4, 2016
Bike got stolen WITH CHAIN i bought this chain because I thought the brand had a good reputation but had my bike stolen less than 2months of having it while it was chained to a light pole. I was very disappointed so know this product failed so miserably especially that the thrives had NO trouble getting pass the chain. I hope kryptonite sees this and does something to improve the quality of the build. June 15, 2015
The theft protection costs extra Kryptonite offers theft protection like extra insurance for your bike as long as you are using the lock at the time of the loss AND you register the lock with them. The value varies by lock, but this one carries enough coverage to pay my insurance deductible so I figured that was enough. What it doesn't tell you anywhere is that this is not included in the cost of the lock. As of now they charge $10/1 yr, $15/2 yr or $20/3 yrs for coverage. It's not a huge expense, but that should really be known before purchasing. Besides this surprise, the lock is heavy duty and feels solid. I assume that if someone really wants to steal my bike, this won't stop them. It will make it really annoying and hopefully cause thieves to pass over mine to an easier mark. Also, regardless of what you're using it for, buy the longer version. As you can see in the photo, just going through the back wheel and around a support for the covered parking at my apartment (all I have to work with) took every bit of the 60" that I had available, and that's with me parked all the way at the back of the parking space where I feel less confident that the bike will be seen by any cars who try to pull in.

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
