The best way is still to get around by bicycle and you can rent one close to tourist information office. There is also a city bike scheme (doesn't work during the winter time, though) where you may borrow a bicycle from any of the 20 city bike stands shown on this map; you'll need to make a 20 Kr deposit to unlock the bicycle and you get the coin back when you return it to any of the bike stands.
