In Copenhagen, we are proud of our bike culture, and most of us are happy that tourists from all over the world want to experience the city of Copenhagen from the seat of a bike. And despite a (mostly) well-functioning public transport system, biking really is the best way to get around the city, day and night.
However, it is a mistake to consider biking in Copenhagen as something quaint or charming per se. It is serious business for those people who use their bike every day.
If you keep that in mind, your experience of Copenhagen will improve greatly. And the locals will enjoy your visit all the more.
