"Unbreakable Deuce" bike lock
 

Hello ... I saw this bike lock at www.unbrakeable.com/Unbreakable_Bike.htm. I was wondering if anyone here has heard about this product and/or seen reviews/comments/test results for it. I'd like to know since I'm weighing my options on which lock I should purchase.
Thanks.

Hmmm, no idea. It's probably just as good as any other U-lock.

The Unbreakable two-part lock looks very much like my "Club for Bikes". The double construction probably makes it very strong as long as you don't pull it out TOO far. Check online to see if anyone has used it; something like E-pinions is a good start.

The claim is it resists prying and hammering. That is true of all the better U locks. I do not believe it resists cutting any better than any other lock. The extention/contraction feature might be usefull. $60 is a lot for a lock. I would like to see them make a claim that mentions other brands by name.

i lock my bike with a regular ulock, front wheel and frame. i have recently gotten lazy about taking one wheel. So now i undo the front QR and close it. Whichever crackhead tries to ride off with my bike is bound for a fun little surprise; possibly a nice fall in front a streetcar. The only worry i have is forgetting to re-tighten the wheel when i get back on the bike.

I didn't see any guarantees in the ad. What's the Kryptonite guarantee?

IIRC Kryptonite guarantees to imburse up to $1000 of the price of replacement if your bike gets stolen on their lock.

I wouldn't spend 60 bucks on a U-Lock with no guarantee.

The X-tender bit looks like a good idea for protecting the front wheel(instead of a cable). For the main U lock though,I think I'll stick with name brands like OnGuard or Kryptonite.

I dislike the Kryptonite locks because a defective one cost me my last bike. I'm stuck with the New Yorker though since it is the top rated lock out there.
My "Club for Bikes" looks pretty strong, but a really determined cutting blade might get through it. Its chief advantage is that it is resizable, enabling you to lock the bike tight to the post so a crowbar can't fit between it and the post.

lxpatterson, better check out the many posts that show the correct way to lock a bike. I use it now and don't think anyone is going to get away with my new one any time soon. put the lock around the rear tire, inside the triangular bit of the frame that attaches to the rear wheel. Then attach the u lock to a secure post. That bike ain't going NOwhere.
I use a second U lock on the front wheel and will have spikes put in to replace the ridiculous QRs currently there.

Was yours one of the ones that missed the Kryptonite recall last year when everyone found out they could be picked with a BIC pen? That whole deal sucked. Sorry to hear about your bike :(

Bike locks vary greatly in quality. In tests published in "Cycling Plus", some u-locks from pretend lock companies such as Master lock are opened in a few seconds. The best u-locks are those that have earned a "gold" rating after testing at Soldsecure. Those locks require the skilled use of expensive tools to get opened. Of course, any lock must be used correctly.

Nine out of ten times, if someone says their bike was stolen while using a Kryptonite lock, the owner failed to use the lock correctly, or may have forgotten to use the lock at all. That is why the Kryptonite theft insurance policy requires returning the broken pieces of the lock...no broken pieces means the bike was never locked in the first place. (What crook is such a "neat freak" that he would break open a lock, and then pick up the pieces of the lock and carry them away?)

I had an old style kryptonite, the style that had a bent bar on one end, and I lost my key. I was locked to a railing at a downtown building. So I watched as security/maintenance guy drilled the barrel of the lock using 3 bits of successively larger size. Portable makita drill, nice powerful battery. In 3 minutes I had a destroyed lock but I was back on my bike. So I don't understand why someone hasn't engineered a lock that even if the key-barrel is destroyed, the lock doesn't fall apart. If they had a spring holding the lock together, in the absence of a key applying force leveraging the clasp open on each end of the U, they could make it much more secure. Any idea if there is such an animal?

Kryptonite insurace policy is probably not worth that much.
