Copenhagen has all the public transport options you can expect of a large city so getting around should not be a problem. Everything from local trains to busses and bikes are an option here.
Copenhagen is divided up into zones and your journey will be charged depending on how many zones you travel through. There are a number of ticket types:
This is similar to the Oyster Card used in London. Here you can put money onto your card and essentially pay as you go when you touch in and touch out. It is gradually being rolled out across Denmark.
You buy this for the number of zones you need to travel; the minimum you can purchase is 2 zones. Each card has 10 journeys on it. Many people in Copenhagen will have a number of different cards depending on where they travel. For example if you want to travel around in the centre of town, a two zone card will suffice (including to Refshaleøen) but if you are out near the airport or further a 3 zone card or more may be necessary. The "klippekort" can be quite confusing to a foreigner so ask a local and you'll soon be on your way. Remember to stamp it before you start your journey!
You can buy something called a City Pass that allows travel for 24 or 72 hours at a time.
Single tickets are also available for the number of zones you require. You can buy these from machines at all stations.
The S-Tog (Local Train) is a comprohensive network of trains servicing the suburbs of Copenhagen from key points in the City. It can also be used to transport you inside the City Centre from north to south.
Here is a map:
The metro services the most central areas of Copenhagen from Vanløse in the West to the Airport and Vestamager in the South East. The trains run regularly and are driverless. Presently when going to Refshaleøen, you can change to a bus at Christianshavn station.
Note: a third and fourth Metro line are currently under construction in Copenhagen and many areas of the city are currently construction sites as a result.They have generally been decorated in order to make them look more pleasing to the eye.
Here is a map:
The city has a very broad network of busses that will take you to areas not served by trains or the metro. Types of buses vary from standard buses to A-busses (that stop regularly) to S-buses (that have less stops).
Currently one bus line serves Refshaleøen, where the B&W-Hallerne are located. This is line 40, which connects via the City Centre to Nordhavn station. It also stops at Christianshavn Metro station, which is the nearest to the Arena. During the competition, we would imagine that regular shuttles will be provided.
Copenhagen is a water city, with canals and beautiful waterfront areas. As such there is a water bus line that connects Teglholmen with Refshaleøen (lines 991 and 992) via some of the biggest sights in the city including the Opera House, National Library and Royal Palace.

Copenhagen and Amsterdam have a very similar bike culture - Everyone has one! Most of the roads in Copenhagen are equipped with bike lanes on eitherside and it is the most common way for people to commute around the city. There are many bike hire places and also a number of free bike hire racks all over the city. Not only is this option environmentally friendly, it is also a great way to acquaint oneself with Copenhagen.
