"Self-Destructing Bike Lock Gives Thieves the Ultimate Disincentive"

From Wired.com: Self-Destructing Bike Lock Gives Thieves the Ultimate Disincentive

The StayLocked secures the bike by making the lock part of the bike. If it’s broken, the bike is unridable and, parts aside, valueless. Andrew Leinonen, a Toronto-based industrial designer and cyclist, created the prototype bike after years of the security anxiety that comes with being an urban rider.

The locking mechanism comprises a section of the seatstays — the two tubes that extend up to the seat from the rear wheel. Leinonen installed a universal joint at the junction of the tube and latches in the stays to secure it to the frame.


The locking section of the frame swings to secure your bike to a meter, post. Should an ignorant criminal break the lock, the chain stays — those tubes extending from the rear wheel to the crank — won’t support a rider’s weight. The bike will collapse as the thief tries to ride off with the plunder. Unfortunately, whether the culprit realizes the destruction before or after breaking the lock, all parties are left without a bike.
