Bicycle bridge in Copenhagen on Flickr.
Going back to visit Copenhagen for the first time in 7 months, it really strikes you how bicycle culture is so deeply rooted in the city.
By bicycle you can literately go from anywhere to anywhere in the city within the space of 20 minutes.
But the biggest difference between London and Copenhagen is how socially recognized it is, even to ride your bicycle into the night life. Something many Londoners find silly.
