 Beast of a U-LockMay 25, 2008
By Physics Teacher
"Birddogthecat"
This thing is the Kong Kong of U-Locks. The useful cable that comes with this set is excellent. I believe you would need a cutting blow torch to get through this thing (the U-lock not the cable). Thoughtful design with the dust/water protection drum that rotates to protect the entrance to the keyhole.
There is no place to mount this huge and heavy thing on my bike (full size mountain). With a water bottle cage + a small pack that hangs from my horizontal frame bar, I must carry the U-Lock in the Topeak Basket behind me. AND, it is HEAVY!
Be aware, this Theft Protection Program they tout is a bit of a scam. You must pay for this additional service. Also, you cannot register nor sign up for the Theft Protection on line. You must first print out a form(s) and mail it (them) in. The address is not on any of the forms. You must go back into the site to locate the mailing address.
The process of signing up for eventual support and FAQ information is a complicated event that required setting up an account that duplicates many of the registering steps and information you have just completed earlier.
BUT: This thing will definitely deter any thief that I can imagine. Isn't that the primary function anyway?

 TERRIBLE KEYJul 18, 2008
By DaliDrama
After moving to Los Angeles, I needed to buy a second U-LOCK as bike's are a hot item to be stolen. One u-lock to lock my front wheel to the frame, and the second to lock the frame, back wheel, to a post, etc. I bought this U-LOCK not knowing the company, but it was sturdy and good feel and at a good price.
I had a HORRIBLE experience with this lock. My second time using this, the key broke off like butter while I was opening it. I have owned many U-LOCKS in the past and know how to not force the key, so I wasn't using much force at all. The key broke off inside the lock, leaving me stranded. I'll avoid my heroic details of finding my way home to then return with the 2nd key and plyers to remove the stuck key.
The key (you get two) that is made for this lock is EXTRA thin. All U-LOCK keys are thin and should never be forced, but this is a terrible design and major flaw. It's a good lock, but comes with a terrible key, so I would not suggest buying this.

Strong, Safe and BIGOct 27, 2005

Yup, this is a big one! I can't imagine ANYONE being able to steal a bike (if you attach it like they tell you to with the cable) or your front wheel/tire -- and you don't have to take it off the fork to secure it!!! That's a shortcoming with a lock that DOESN'T include a cable. Even with a quick-release front wheel, it's a pain to take it off and then put it back on (straight) when you return to your bike. But if you don't have a way to carry this thing, you might decide it's too big and bulky. I've decided it's worth the trouble of lugging it around, but then I ride in the city and prefer to have a bike to ride rather than an empty front fork -- or worse -- an empty bike rack.

Right now I am in my room...Jan 17, 2007
By Hal Emmer
and my bike is at class. I spent 10 minutes fiddling with it, and could not get it open. The key turns the lock, but its stuck good. It often didn't open on the first try, but now it's completely stuck. I will try another key, but I'm not happy now, after having to walk back.
edit: I found that knocking on the side of the lock barrel helps the most, as well as rapidly turning the key. Pulling on the U is useless. I added some oil (low temperature engine oil), and it seems to be much better. I think it is worst in below-freezing temperatures. It is better than it was, but DO NOT RECOMMEND. If you haven't bought it yet, buy a different lock.

Weakly constructed key makes this lock a BAD buy!Oct 22, 2009
By mashtar
The key on this product has a thin area right above the notches that fit the tumblers. In my case, this caused it to break off in the lock earlier today (I did not apply excessive force, knowing from experience the hassles a broken key can cause ). Now, the only way of getting my bike off that stand is for me to go home, bring back my rotary tool and cutting disc and have at it (if that works, this thing is hardened steel) . The lock itself might be as safe as the Bank of England, but I would advise against buying this product because of the key.
Update: the "13mm hardened steel shackle" on this lock took about five minutes to cut through with my little-bitty cordless Dremel, so I shudder to think how easy a job it would be for any thief with a "professional" tool. In retrospect, I am happy the key broke off and that I had to get rid of this lock.
