騎自行車的人都有這樣一個愿望:有一輛永遠不會被偷走的自行車.近來智利學生就發明了一種防盜自行車。

Wall Street Daily: Being headquartered in Baltimore, many of our employees at Wall Street Daily bicycle into the office. It's convenient, healthy and avoids that awful bumper-to-bumper commuter traffic.

The only downfall with bicycling, though, is protecting your ride once you've reached your destination. Bike theft is especially common in every city, especially in Chilean capital, Santiago.

After being fed up with having their bikes stolen more than once, three Chilean students have finally created the "unstealable" bike, what they refer to as the Yerka Project.

So, how did Cristobal Cabello and his colleagues create a theft-proof bike? By making a lock that renders the bike useless. It actually defeats the point of stealing it.

"So basically you lock your bike up on a lamppost, tree, or fence, and you open up the lower part with this pin. You divide the parts, you lean it on a tree, fence, or bike rack, and you pull out the seat pole. You cross the two parts together, and then you fit in the lock, which goes on the lower part."
