Researchers develop a theft-proof bike

You may never have to worry about your bike being stolen!
Researchers in Chile have developed a theft-proof bike that doubles as its own lock.
Three engineering students Juan Jose Monsalve, Andres Roi and Cristobal Cabello have built the first working prototype of the bike, code-named the Yerka Project.
The bike's down tube at the bottom of the frame splits apart and wraps around an object such as a post or tree, and the bike's seat post is then slotted through both ends of the down tube to complete the lock, 'CNET' reported.
Once everything is in place, the owner simply takes out the lock pin on the end of the down tube to seal the lock. The whole process takes less than 20 seconds.

Stealing the Yerka Project would require breaking the frame which renders the bike useless.
However, the current prototype does not secure the wheels and saddle.
