Easy to use...period Super easy to use and cable that comes with has a dual purpose to secure riding apparel just by using the helmet lock under the seat...I love it August 25, 2014
great bang for the buck Everything can be stolen. The bright yellow will help deter thieves from your bike. This will really help slow down any potential threat with its heavy duty constriction. Way more portable and usable than a cable lock. June 23, 2014
Does what it says I put this lock on my bike every time i get off of it. It goes on and comes off very easily and quickly and give me a sense of security when im not watching it. Also, as an added bonus, the yellow of the lock blends very well to the fairings on the bike. May 27, 2014
It Locks It works. I hook the leash to my rear brake pedal and the lock to the rear wheel brake rotor. The yellow paint seems thin and quickly comes off, but I don't really care. Use the leash! I failed to hook up the leash once, and I started moving the bike, but thankfully it was on flat ground and there was no damage to the bike. I do not know about how easy/difficult it is to defeat, but it is metal not plastic. If I am away from my bike more than 20 minutes, I use this lock, the steering head column lock, and my comprehensive insurance policy. I believe this is the best cost/return ratio you can have.

Newer Model I received the newer model of this lock. Its round shaped and heavier than it looks. Well built and strong as you would expect from Kryptonite.To bad it doesn't specify that is comes with the cable reminder, I bought one as well and spent 8 bucks more. Please correct the description Revzilla. May 12, 2014
Love it Awesome lock fits perfect on the rotors and lets me sleep at night since my bike is parked outside. May 5, 2014
Feels cheap.. plus pin makes look weak.. I bought this lock.. but I returned it.. after looking at the pin..decided to go with the xena lock. April 30, 2014
Does what it needs to at a great price Cheap, durable, effective, I see now reason to pay for the more expensive options. March 24, 2014
