I was in Antwerp this year for the first time thus I can agree with the article. It really is super easy to move around with the bike. Countries like Belgium, Holland, and Denmark are famous for that. They even have big parking lots for bicycles next to train stations. So that you can come by train, pick up your bike and continue your way. And they do so despite bad weather.
In general, in the European cities east Berlin wall, the bicycle infrastructure is not that great. Yet, there are European funds that close that gap and you can see many cycling roads in countries like Poland or Hungary.
There are also European bicycle 'highways' called Eurovelo that are being built from the European money. I think Europe is going into the right direction.
