This is an absolutely amazing innovation, but bike thieves have already progressed to using powder-actuated pistons in order to break the internal mechanism of a lock. Much faster and easier than cutting anything.

How does that work?

I wish there were a way to get a sample of this to the lockpickinglawyer.

I'm guessing he'd bust out a blowtorch and make short work of it.

Or just pick the (literal weak link in the chain) cheapo lock attached to it. I'm pretty exhausted from listening to people boast about the amazing lock they put in their door, which has full-length windows on both sides. Or their super sturdy door with a generic kwikset lock. The evergreen penetration testing motto is appropriate here: the goal is simply to get on the other side of the door.

> The freefall of grapefruit from 10 m does not damage the pulp[1] because pomelo peel consists of vascular bundles and an open-pored cellular structure with the struts made of parenchymatic cells. I have a Marsh grapefruit tree, fruiting now (southern hemisphere) as it happens, and I note that it produces particularly pithy progeny. (Ignoring for the moment that Pomelo is one of the parents of the modern grapefruit.…

In any major city really the solution is to never lock anything up in public that is worth more than $400 or so. I have two road bikes, the insurance replacement value of each would probably be $3000, and I wouldn't even dream of buying a lock. I literally don't even know where my lock is. The last time I saw a lock was when I put it in a box of stuff on a shelf in my garage 10+ years ago. If you have a nice road bik…

Not sure I follow, I take it by implication you have renter's or homeowner's insurance, in which case your replacement cost is the deductible - and $400 is a common deductible. Now, getting a bike set up the way you had yours is a pain, granted. I think it's pretty unlikely that even desperate thieves would saw through your frame, they want to be able to resell as much of the bike as they can, and the frame is a fairly valuable component...

This non-cuttable metal material sounds extremely useful: > "Security applications such as doors or barriers (as protection from forcible entry attacks) are obvious ones. However, our material technology could also be useful for enhancing the cutting resistance of shoe soles or protective clothing. Workers could benefit from non-cuttable elbow pads or forearm guards in environments with industrial tools." As someone…

This material is completely unsuited for making shoe soles or elbow pads; it's a two-inch-thick plate of aluminum foam with half-inch ceramic spheres embedded in it. Around that they welded steel plates to give it a uniform surface.

It'd make a very heavy but uncuttable door, but you can't make hinges or locks out of it. It would be a good material to make safes out of; those already have thick walls of composite materials designed to blunt drill bits.

I've managed to keep my bike locked up outside OVERNIGHT in San Francisco (Washington & Polk St.) for a year now. How I did it? The short version: one very good lock (Viro Euromonolith + Peewag security chain, $175), a second good lock (kryptonite, $90), and an okay lock (Abus, to keep them from stealing the basket, $60).

I've also had 3 bikes stolen, the rear wheel stolen, the basket stolen, the front brake stolen, the seat stolen, but now with all the locks there is much less stealing.

I want a bike lock made of this stuff
