Bikes are welcome in the Metro. You just need to buy a bicycle ticket and remember not to bring your bicycle at rush-hour.
You can buy a ticket for your bicycle in the ticket machines which are located in all stations. A bicycle ticket is valid for two hours in all zones (this covers greater Copenhagen).
During rush-hour (between 07:00 and 09.00 and between 15.30 and 17:30) bicycles are not allowed. If you travel with a bicycle during rush-hour you will be fined and asked to leave the train.
In June, July and August, bicycles are allowed 24 hours a day if you can present a valid bicycle ticket.
Bicycles are to be placed in the middle of the train. There are parking facilities for bicycles at all stations.
