I never once heard that about Amsterdam. The YouTube channel NotJustBikes goes on and on about how amazing is the bicycle infra in Amsterdam (and other cities in the Netherlands). Can you be more specific?
Oh don't get me wrong, the infrastructure is amazing! Commuting to Amsterdam is mostly just bad compared to commuting to other well-connected places. There's only so many times you can get stuck behind a group of tourists blocking all the check-out gates simultaneously for 10s of minutes on end before it gets on your nerves.
