Behold! The world's first 'unstealable' bike
So how does it all work? Well, three Chilean inventors have designed it so it will breaks if anyone nabs it.
Cristóbal Cabello, Andrés Roi Eggers, and Juan José Monsalve, came up with a solution which sees the bike itself becoming a lock, with part of the frame splitting in half, which is able to be clicked into the seat shaft, so you basically end up clipping the bike itself, around things.
If a thief wants to get at it, they'll have to break the bike, or try and make off with a bike that has an unstable frame.
The creators claim that it takes a mere 10 seconds to assemble the lock, and the Yerka website says: "Introducing a bicycle locking system designed to keep you feeling safe. We went back to the roots of security and made a paradigm shift: Make a lock out of the bike."
"Now a thief would have to cut through the main structure to take the bicycle, defeating the purpose."
So, if you've read all this and are thinking that this doesn't make a blind bit of sense, fear not. Watch the video below and see how it works. Or indeed, watch the video and try and work out ways in which the Yerka won't work.
