metal bike puzzle

Very tricky puzzle of Jean-Claude Constantin: Remove the bicycle lanyard from the rest of the puzzle.

According to Jean-Claude, this lanyard is the chain that ties the bike. The puzzle is so difficult that even the author himself takes several minutes to solve it. At the Nuremberg fair we asked him to show us how it resolves, but he refused, saying that it takes too long … and you, how long is you going to take?

CHALLENGE: Remove the free-moving ring from the rest of the puzzle.
Average solution time: 2 hours – all life.

A Jewel for the collection of every enthusiast!
