While it won’t prevent cutting, the Forever Lock does claim to be pick proof with a very clever design that hides the key chamber and cylinder.

The video above shows how it works (skip ahead to about 2:30 for the real action), and we’ve put a few screen caps after the break. Basically, you rotate the red end to access a blank key slot. Insert the key, then rotate it back to position the key for entry into the cylinder. Slide the lower section in, then twist that part to rotate the key. Clever, for sure.

Want one? Head over to LockMan28’s YouTube page and message him to get on the waiting list. Word is they’re not only very limited and pretty expensive (estimated at $140 plus shipping), but also come as-is with the likelihood of no future support from the Asian manufacturer unless they decide to crank up the very complicated production.

  1. Cool, but I was always under the impression that the locks are cut or broken and rarely if ever picked int he real world. But if I am wrong then this is a cool solution.

  2. I give that lock a lifespan of 30 minutes, tops, in Santa Cruz, CA. And that’s with the lock attached to a bike. On a moving car. Going 55mph.

    Santa Cruz has some very talented bike thieves.

    SurfTown USA, my butt. BikeThieveTown is more like it. Bunch of tweakers. Locals always carp on people from “over the hill” (aka Silicon Valley), but at least I can keep my garage open for more than 3 minutes without some patchouli-smelling crack peddler shuffling through my stash.

  3. Cool design, but it solves the wrong problem. Bike locks are already extremely difficult to pick – thieves will break or cut the shackle instead.

  4. In future please talk to bike shops before designing a product. I have, in the better part of a decade, never seen real evidence of a picked lock. Theives break or cut locks. Its been a long time since the Bic pen fiasco.

  5. A few things.
    1- If you like your bike don’t leave it unattended.
    2- Who spends $150 for a lock that takes 10 minutes to use each time for a problem that does not exist.
    3- If they design a lock that stops freezing and cutting of lock that would be good.
    4- Someone tell that guy not to get too excited and buy a bunch. He will be stuck with them.

  6. 1. Oh joy because Im sure ill never accidentally forget my key in the chamber

    2. Besides who wants to spend all that time to lock up a bike or, even worse, try to teach a customer at the shop how to use it…

    3.The hinge design probably makes it harder to use.

    4. This guy should never make another video. Get to the point already, its not so clever of a lock that it takes you that long to explain how it works…

  7. very elegant, but bikelock companies got away from keys in the end of the crossbar many years ago, not from picking but from what is known as the NY method (originally developed in Dublin). Break off the end with a pipe.

  8. Yeah, very good defense against the attack no one uses, by adding more leverage for a pipe. And look at that slotted end where the hinged shackle attaches, that combined with the large width make me think this would pop right open with a jack too.

  9. Chuck Dick: why don’t you got to Santa Cruz and them know how much you hate them, and leave us alone here to comment on the article

  10. Some commenters seem to have problems with reading comprehension. Despite the fact that the writer clearly says that ‘it won’t prevent cutting’, some commenters present this piece of information as something the writer didn’t think of.

    And who knows, perhaps bike thieves somewhere in the world do pick bike locks. Anyway, a nice invention that might find use somewhere else too.

  11. Who cares? Bike thieves don’t pick locks. The old use a BIC pen cap trick (search youtube) only works on really old U-locks. Bottom line is that strengthening the keyhole area ain’t gonna do ish to stop a bike thief because he ain’t gonna jack your bike by picking the lock anyway.

  12. Patrick at 0:44 seconds you can see that the guy already has the key in the lock on his second attempt. The pick video is a fake and dishonest. Still this lock does not answer the claim of cutting the lock. Which in all my experience with owning a bike finding my locks in pieces is generally what happens now get me a lock that is uncuttable and unpickable I might spend at least 200 dollars on that.

  13. just want to re-iterate what’s been said, for the same money 140 you could buy 2 kryptonite 18mm u locks or 3 or 4 cheaper ones with a flat key and newer u locks have been proven hard/impossible to pick anyway. a thief does not care about preserving your precious, expensive, pretty bike lock, he/she wants to grab n go which means a destructive, ham fisted method to break it and cut it, they are not going to waste time going through a procedure to preserve the integrity of the lock LOL… I would surely buy one if it were closer to £14 but 140 is a joke and of course trying to prevent a problem that 1/10,000,000 thieves will bother with. to try and pick that might take years and years. the opening line “while it won’t prevent cutting” tells the reader everything they need to know in one sentence that it’s just another generic u lock that works just as well as any other u lock but this one has a new gimmick. i would have one mind but for in between 14-20 its not worth any more than that, they could have invested in a solution that makes cutting more difficult instead as that is the major concern not picking, thieves are too boneheaded to pick lol
