These were fished out down the street from my apartment.
Neither bicycle is mine... Both appear to have been in pretty good condition before some drunk college student threw them in the water. Such a waste! I prefer a good old bicycle tree to this kind of nasty prank. I'm sad for the owners of these bicycles.
The closest bicycle even has an unused extra chain wrapped around the seat stem.
Lesson: always use a canal dunking prevention chain when parking overnight in Leiden.
