Every year there are two huge rides from Nørrebro in Copenhagen to Bakken (oldest amusement park in the world), once for the opening of the park and once for it's closing.
On a good day, there can easily be 5,000 motorbikes filling up the streets. Such procession requires roads to be temporary closed for other traffic and to have special escort from the police. This video shows the police leaving at the end of the day, once they've done their job.
The video is from August 2018
