An entreprenuer has come up with what he says is an ‘unpickable’ bike lock, thanks to a clever mechanism that never gives full access to the chamber.
The key is inserted into a blank barrel, which with a few twists and turns of the outer housing frees the shackle, as shown in the below video.
Having posted the video to a lock picking forum, the creator (Marduk28) has left many stumped as to how they’d go about tackling the hidden chamber.
The creator said on his YouTube page: "I have been authorized to distribute only a very few number of these locks when they are made available. After that I may have more opportunities to release additional units based on demand. However, the first batch will not be available from the manufacturing plant for about another 1-2 months. At this time, I am only a small businessman and production of this lock is not optimized."
The price is likely to be around $140.
