Smart Lock, the Exploding Bike Lock

The Smart Lock by Michael Lambourn is filled with pressurized, colored liquid and explodes upon being cut. Along the lines of the exploding ink used in banks, it is startling and makes the culprit that much more identifiable. Not on the market yet and likely not the most practical of lock designs, it is pretty interesting nonetheless. Click through for a video of the design in action, staining everything in sight once compromised with bolt cutters.

    I wonder if you could get some vandalism charge for getting paint on everything around your bike. Or maybe they could tack that onto the thief’s bill.

    I’d be pissed if my bike got covered in dye because some rich dude locked his Specialized Allez on the rack next to me, and his exploding lock got compromised.

    I’m desiging one and filling it full of shit, imagine the thief laughing as they cut the lock and getting a mouth full of rancid runs. I’ve already applied for the copyright so don’t even think about it.

    [...] Dave Pomphret and Karl McCracken would like to see the lock filled with ebola virus. I’d choose Napalm. Hat-tip to Urban Velo. [...]

    I love it. I’d always use my U-lock, but if you could fill it with ink/acid/stinky liquid… ohhh how I hate bike theives.
