You may have seen the YERKA and its integrated, supposedly theft-proof locking system floating around the Internet before, but today the Chilean bicycle designers have officially launched their crowdfunding campaign in an effort to transport the YERKA from the virtual streets of the web to the actual, sticky-handed streets of your neighborhood.
The YERKA bicycle locking system consists of a casted aluminum lock built into the seat and down tube. When it's time to leave your bike unattended, its saddle and seat post lift to remove, while the tube disengages and opens outward at its midpoint, revealing a set of cutouts at the top and latch at the bottom. Slide the seat post through the holes, insert its end pin in the bottom of the tube, and remove the YERKA pin/key to lock. With this type of security system in place, a thief would have to cut through the entire main structure of the bike to steal it, thereby removing any value the "score" might have had.

In addition to the frame's security provisions, YERKA's wheels will also include anti-theft nuts (accessible with an included key), as well as a built-in Bluetooth system so riders can always find their bikes if they happen to forget where they locked it.
YERKAs come in a variety of colors, which backers can select when they pledge for their own unstealable bike on IndieGoGo through April 18, 2015.
