The cable is strong and I use it to lock my front wheel, I got a small 5mm cable to run through my seat and rear bike rack and connect them both to this lock using the Sheldon Brown method of U-Lock usage. ([...]
I liked this lock, but it turned out to be a bit short for my City style bikes rear tire with full fender.
I had to spend so much time jostling to get this around the bike rack and the bike. I do think this lock will work for many people and if I was willing to deal with the extra locking time needed I would still be using it.
But I have since upgraded to a OnGuard Brute STD 5001 Bike U-Lock It is a touch wider and a few inches longer and also thicker U shackle and the lock is also thicker. BUT this added strength adds weight and if your in lower crime zone, I'm in NYC so its kinda high, you could get away with a OnGuard Bulldog DT 5012 Bicycle U-Lock and Extra Security Cable which has the cable and is a little longer.
But having said this, I do like this lock and if you can deal with the short U shank its a great lock.
Sheldon Brown himself preferred the mini U Locks because it is much harder to get a jack in them to crack them open, no space.
When I bought the OnGuard Bulldog MINI lock, I used it diligently, and I was mostly hoping people wouldn't try to steal my bike. I was right - I had a crappy bike, and when it was locked, it definitely wasn't worth the effort.
Last month I upgraded and got a nice, new bike. A bike worth stealing, although it wasn't the top brand name or anything. I continued to use my OnGuard Bulldog MINI lock, which just barely fit around the front tire (skinny street tire), frame, and the bike rack. Not a week after I bought the bike, I go to unlock it one morning, and notice the lock was TORN UP. Someone had tried to cut it in about 4-5 different places - near the key entry, all around the U-loop, and on the bottom opposite the key entry. The lock held strong. The cuts on the U-loop went through the rubber but didn't scratch the metal underneath. The cuts on the lock left gauges, but it retained its shape and is still usable (the key catches a bit though).
I just ordered a new lock of the same type. Any lock that holds up to an attack like that has performed better than expected and is a good lock. Go ahead and throw away the thingy to mount it on your bike though.
Lock easily fits around my frame and rear road bike tire, or the frame and a regular bike rack. I have not used the included cable yet because this is such a wonderful deterrent already! Buy this (you can find it on amazon without the cable for $20) and you won't regret it. I have not broken a SINGLE KEY in this lock because I never force the key to do anything it doesn't want. It is very easy to tell when the key is ready to unlock because it is a fluid movement to unlock this lock. I don't understand why anyone would try to force their way into the lock with a key. Take it easy, and it is very quick and easy to unlock.
The bike frame attachment is a little flimsy. The first month I had it, if the lock was "locked in," then I had to unlock the actual lock before it would come off the attachment. Now, all I have to do is tug and pull it off. It starts to get loose after a while, but I just tighten it back up. The bike attachment hook also becomes loose soon, but I now that can easily be fixed with a good super-glue. I attached the lock to the frame tube right below the seat so that gravity is helping keep the lock in the attachment
Economically small and lightweight
Looks very sturdy (deterrent)
Five keys (the light on one is kind of a sham though)
Cable for the front tire and bike seat
Comes with bike attachment
A couple people have told me it looks good(just black - you can slide the dumb yellow rubber ends off)
Weather-resistant(bike stays outside for everything but northern Indiana winters)
A little heavy for the back pocket, although it fits
Attachment is just a tad finicky because it is plastic. But it shows no sign of breaking any time soon.
Now I did a lot of consumer research before picking this one. This is a great buy. I wish bike locks were cheaper but they aren't. This is an inexpensive model that beats out most other bike locks and holds its own against Kryptonite's NYC Forgettaboutit models, which you're paying for a name, like Apple, when you can get an affordable and smaller Creative mp3 player...
If you need a good lock on a college campus, JUST BUY THIS! Let someone's cable lock be cut, not your Bulldog.
