Attack Video titles Short.mov

The TiGr titanium bike lock, conceived, designed, and engineered by John and Bob Loughlin with product design by Joshua A.C. Newman, is designed to be elegant, but made of tough stuff. Here, John attacks a D lock and a piece of stock used for the TiGr with the same tools. The end result? The TiGr lasts almost twice as long against a concerted cutting attack.

(I've sped up the cutting footage here by 4x.)

TiGr is up on Kickstarter right now. John and I are trying to get funding for a first production run so we can produce a lock as elegant as the bike it protects.

If you're at all skeptical, please don't back the project. Kickstarter is for enthusiastic early adopters, helping us make a thing real.

This is an uncontrolled environment and we're obviously interested parties. This is a demonstration, not proof; for that, we're getting ART to do all of their testing; their interest is in grading products accurately.

that looks like a really cheap U / D lock you tested it against... like the kind you get for 10 bucks at walmart. i had to saw my kryptonite off once after the key broke off in it and it took about 15 minutes with a grinder with blade like in your example, so i wouldn't really consider 46 seconds secure. also you need to double your U lock times because you need to cut through both arms of the U lock in order to actually get the lock off, not just one.

One possible flaw in this video - you should have used a fresh blade for each cut, with each of the first two tools. And the video should clearly SHOW you installing a new, fresh blade for the second cut.

With the bold cutters, you should have turned it the wide way as well, so that the "too thin" profile is no longer a factor.

Remaking the video with those points in mind, will produce a much more compelling (and resistant to detraction) demonstration of your lock. :)

Should have changed to a fresh blade when you switched to the second metal...

You guys have a lot to be proud of. I like how it protects the frame and both wheels without requiring me to unmount one of them. I do have to admit that if I were a thief I'd go out and buy myself a cordless grinder. I did some work on secure concrete some years ago and found that mixing boxite in concrete nullified grinder attacks - it trumps its hardness and just wears the wheel down. I wonder if you could do some kind of coating to accomplish the same thing.

@davyc412 yes i agree... this lock is a good lock if you are not going to be away from your bike for too long and it's not left completely alone all night... don't really consider this lock as a "replace all locks" kind of thing..

the fact it's easy to take with you is really the only good thing about it in my opinion.. and PS: some of you people have to realize that no lock is 100% theft proof.. you need a high security bank installation to come close to that.

I had a bike stolen once, which I recovered twelve blocks away with force. With that said, bike locks suck. They're heavy, bulky, and generally a pain to use. Your design doesn't look like much less of a pain to use than any other bike lock. It actually looks more difficult. And how would you strap the lock to a mountain bike which has cables on the top bar?

no ear or hand protection while using the grinder? you crazy. bad example for the kids

Thanks for watching the video. The Ti sample used in the video was .125 thk x 1.25 wide, same cross section and same alloy as the 1.25 version of the TiGr lock. The U shackle was a name brand and .475 diameter hardened steel.

Once the TiGr Lock project is completed on kickstarter we will submit the TiGr lock to a certified lab for proper testing.

I also had problems with the demo in this video. My problem was that the bar of Ti he was working with was 2 to 3 times the width of the finished product

I would like to see these same tests with finished products (high end U-Lock) on locked bikes and I also want to know more about the barrel lock and how it is attached to the Ti bar.

OK, so the strap is reasonable against a hacksaw, good against bolt cutters and better than steel with a disc cutter. What quality of D-lock are we talking? A £5 supermarket job or an industry rated sold secure lock? Then there is the part abject in its absence, the barrel lock itself. You can have the strongest strap this side of Alpha Centauri but if the barrel lock is toffee it's all to no avail.
