Optimized for SEO: Kryptonite KryptoLok Series 2 Integrated Chain Bicycle Lock Review

I used it for the first time during a two-week vacation. The look worked perfectly. It's a heavy beast, but that's why I bought it. There are no locking and unlocking problems. The chain cover protects the frame of our bike well.

I use this lock when I know I'm going to leave my bike unattended for a long time. Go to the grocery store or other store. I only use kryptonite locks. Love the key exchange program and the extra insurance.

Great chain for home use but if you plan to travel with it, good luck. It's very hard. I sent it back because I couldn't imagine carrying this chain around in my backpack and I have an Elliptigo so there is nowhere else to store anything. Probably an excellent anti-theft network, but I haven't figured it out.

My bike was stolen from my garage. I have a New York lock for my wife with this one. Castle U is ok but very disappointed with this castle. I bought the bike first because they had security but then you have to pay extra money to secure it - don't worry about that lock.

Bought this chain about a month ago and use it on my new BMX bike to ride everywhere. I almost turned my back on it because of the complaints I've seen about the locking mechanism jamming. I didn't even have the slightest sign that the lock was jammed. Although cylinder locks are a little tricky to lock and unlock unless you insert the key all the way and move the cylinders. I bought a five foot chain, it's a bit heavy (probably around ten pounds) but I wanted to make sure I could fully lock…

In through the rear wheel, out and around the rack, in through the frame, twist to close and those two things don't go anywhere for a while. In fact, the pillar can be the weakest link. Pay attention to the chain NINE mm. This is pretty serious. To be honest I think this is too serious for most users and I would recommend the 7mm version (and a lot cheaper). I wear it around my waist when riding because it's the easiest. It's surprisingly uncomfortable at first, but what's even more amazing is…
