A new bike lock idea

A friend of mine sent this link to me. (I/we have no affiliation with the maker or the kickstarter account.) I thought it looked kind of interesting...

TiGr Titanium lock.

agreed, in my mind, its just an alternative lock to get cut off the bike.  and that much more frustrating for the lost cost of the lock

The video shows me it's about the same as a ulock. Which is great. Everything can be cut with the right tools, but this seems more flexible than a ulock.

It only took that long because he is not using the grinder correctly.  He should have been through the u-lock in less time but he us cutting with the wrong side of the disc and the rotation of the grinder is fighting the cut not helping to feed into the cut.  Notice how much the grinder jumps and how often he has to restart the cut; proper tool use would prevent that and drastically reduce cut time.  He is also using a lock with a small gauge 'U' on it, a larger lock would take longer.  On the saw the increased time is due to tooling, the right blade, speed and feed can make a much faster cut in Ti than he is making; in all reality if he had cut slower the total time would have been less.

 

I also feel compelled to mention that his lock design only needs one arm of the lock to be cut and a u-lock with a design that needs both cut would double the cut time on the u-lock.  At that point with proper tool use his lock is going to get cut in the same amount of time. 

 

Fact: In the age of cordless angle grinders any bike lock is quickly deflatable so your best bet is to be just a little harder to get than the guy next to you.

I didn't get that far into the video and missed the grinder portion the first time I watched. After viewing the video, it is still extremely vulnerable to grinder attack, although it takes a bit longer to cut through. Since I carry two U-locks anyway I could see the usefulness of this particular item depending on its price. Then I could dispense with one of the U-Locks I carry at least. Again, I think they state it best in their own description- "Moderate Threat" areas- so perfect for touring and low crime areas, but I doubt you would want this as your primary lock in the City.

For those of you talking about a grinder attack, looks like they did make a video going after a U lock and one of their locks with a grinder. http://tigrlock.com/pages/2011/04/the-best-kind-of-boring/

I want to love this I really do. I do have to applaud them for being honest and showing how long it takes to break it with a grinder. I currently have a kryptonite NY ulock which I would love to leave at home. I also have a kryptonite chain lock I leave at work and use both when locking up there. This might be awesome for short shopping trips. I would love to see some reviews and the final price.

It's not the same as a U-lock, it's world's better. I love mine.

Where did you get it an how much was it?

I hadn't realized they were bringing these to market already.  Did you get it at an LBS?

I supported the kickstarter campaign but you can now order them from the site, i think they have 2 sizes. It's so convenient to use, quick and really tough.

If it costs more than $150 to replace the bike, it's worth it. Peace of mind, it's worth it. Convenience factor, it's worth it. Supporting Indy American innovation, it's worth it. Enough counts to fill two hands of friends who have used ulock plus cable combos to protect now stolen bikes..... It's most definitely worth it.

once again I will say this:

With the right blade that will cut as quick, or quicker if you can get the right angle on the cut, than a U-lock. 

If you like it great but don't fool yourself thinking it is somehow better than a less expensive U-lock when it comes to locking up your bike.  I have significant experience working with Ti and I can tell you for a fact that it cuts very easy with a grinder.  Look into it's properties compared to well hardened steel alloys and you will be surprised as to just how weak it is in certain conditions.

We have both a corded and cordless at the shop; if you get the lock, or even just the steel bar, to do it I would happily host a test.  It is going to depend more on the brand than type of grinder I think.  I bet a good cordless grinder can beat a cheap corded one and vise-verse assuming the same blade.

The only thing nagging at me a little is the time in the video for angle grinder cut (was it 46 seconds?)

My perception is that a typical cordless grinder would take longer than a corded grinder.  Would love to take a chack at one of these with my Ryobi or maybe Martin's Bosch . . . anyone volunteer theirs?
