Theft-proof bike designs...

[andygates]

Lifted from Wired, here's an industrial design board's attempts at theft-proof bikes.  See if you can find one that *would* work or hasn't been done before...

Erm...wouldn't the easiest answer be "a Brompton and a bag"?

[edit: Although I do like the Richard Sachs cross bike used in the "Crotch Mangler" design on page 2, without the mangler of course...]

I've had an idea.

It's a cable encased in a very loose kevlar sleeve. The space between the cable and the sleeve is filled with the same sorts of fibres used in chainsaw-protective clothing.

The idea is that the kevlar and fibres slow cutting with a hacksaw. Cutting with an angle grinder could result in a nasty accident, when the fibres wrap round the angle grinder.

The bulk of the kevlar and fibres would squish and jam in boltcroppers.

A luxury model could incorporate an alarm.

Oi, DocSquid, are you there?

The dye-filled lock appeals.  Cut it, get spooged; you could use one of the Smartwater systems for an identifiable ID.

Once you get past a certain point it'll be worth going at the object the bike is locked to, rather than the lock itself (which could be dealt with in the villains subterranean lair at a later point (once he has finished his evil cackling).

I don't think she's here; I did not see her much in the old place either, recently.
