@vandenberglegs I get some of the same vibes to be honest, even if the author does say that it is about looking at sustainability within the context of bikes! Arguably that is important and not suprised that there are issues. Also: newer bike designs and materials make cycling easier for some, which is left out.
Also feels like the overall picture of maintainability is a bit too grim. Lack of standards is a nuisance but you can mostly get spares.
