Everyone looking for a cable lock should already know that ALL you expect is a minor deterrent, and ALL you can use this for is to secure your front tire to the bike frame. This cannot be expected to be a primary security device to secure your bike.

For your PRIMARY security device, you need to get a Kryptonite New York Fahgettaboutit Mini Bicycle U-Lock (3.25 x 6-Inch), or something very close to that.

What you need in a cable lock:
1. convenience: has to have mount with easy on/off
2. small size: so that it can be mounted to frame easily (the Kryptonite Hardwire 2510 Key Cable Bicycle Lock is a perfect example of what NOT to get. Way too big and unwieldy.
3. KEY (all combination locks can be defeated just by pulling on them and turning the tumblers)
4. Advantage goes to locks that can be closed WITHOUT having the key inserted. Believe me - it's a huge advantage.

With that in mind, this cable lock fills it's role perfectly.
Small enough to fit on the frame of the bike easily. It's as large and secure as you'll ever get in a cable lock and still be able to use it. Example: I have the Hardwire 2510 also, but it is just too too large to fit on the bike frame, and is very inconvenient to use. I bought this afterwards, and it is what I will use instead, just to secure my front tire. The NY Fahgettaboutit secures the frame. It is a HUGE advantage that you can close it without having the key in the lock (UNlike the 2510). I do not agree with the criticism that you cannot uncoil it - it is as easy to uncoil this as any other cable lock. You WANT it to coil itself up into a tiny ball so that you can mount it.

Special note: the keys are very tiny, and very thin - would be easy to snap one off if you really forced it. You can get free replacements from kryptonite, but you'll want to think twice about letting your 6-year old use this lock (also because he might lose the keys).

Special note #2:
This comes with its own mount. You canNOT replace the mount with the Kryptonite EZ-Bracket Kit - it does not fit this lock. As long as you don't break the original mount, you'll be fine.

Summary: great cable lock for the LIMITED security that any cable lock can provide. Make sure to use a QUALITY U-LOCK as your primary device. I'd give it 5 stars only if it could be used as a primary deterrent, but there is NO cable lock that good.

Thick cable but more than half of diameter is plastic/rubber. Very thin wire, parked bike in front of building with cameras. Took someone a few seconds to cut through the lock.

1.0 out of 5 stars Not secure enough, December 6, 2009

If you live in an area where bicycle theft might be a problem, this lock is not secure enough. My Trek was stolen in less than 2 weeks when I left it locked to a bicycle rack during the day while at work. Not such a bad neighborhood. Bad luck, though!
