The bicycle helmet debate has raised its ugly head in the most unlikely city, Copenhagen. So how did a 100 year old bicycle city find itself embroiled in an argument and its bicycles in decline?

This video is part of a global series of films documenting the stories of the world’s One Billion Bicycles, filmed and edited by independent filmmakers Bojun Bjorkman-Chiswell and Sarah Cowhey.

Created by the filmmakers to unearth the stories of the world’s bicycles and its importance to humanity, the film series journeys across 5 continents, 20 countries and over 140 interviews with high-powered ambassadors in Bejing through to a man in a bicycle wheelchair in the dusty streets of Mozambique.
