Though more than a decade has passed since the Shanghai World Expo, it is worthwhile remembering the Danish pavilion in relation to biking. The concept of hedonist sustainability was applied in this singular project to reach the conjunction of social, economic and environmental concepts.

The Danish pavilion consisted in a double ellipses in 3,000 squared meters. The inner one was dedicated to pedestrians and connected to many rooms in which exhibitions and conferences were done. The outer ellipsis was ridden by thousands because Bjarke Ingels, its designer, imagined that bikers must get the top of the pavilion, stop their bikes and walk through the inner ellipsis to access the activities within the building. And it worked.
