Bicycle Thieves, Give up. This Cycle Can't be Stolen

London: Three engineering students in Chile have developed a bicycle called Yerka which they claim is impossible to steal.

The website for the project shows a smart looking bicycle which can be locked onto its own frame in 20 seconds in just three small steps.

Unlike bicycle locks which can be easily cut with a hacksaw or bolt cutters, this cycle has a thick frame of steel protecting it.

The only way to steal the cycle is to break the frame, and then the cycle is just broken metal, unusable by the thief.
