Beijing's air is so bad, cyclists have taken to creating their own breathing contraptions just to get by.
At least, that's how artist Matt Hope is handling the current air quality crisis. Hope has invented a sort of "breathing bicycle," which he uses to travel around the city. The equipment used in construction is pretty basic -- an IKEA garbage can, fighter-pilot breathing mask, moped helmet, wheel-powered generator and home air filtration system. When he pedals, Hope activates a system to filter out haze and generate clean air.
Hope told Reuters he built the bike "as a way of protecting himself from air pollution." Below, photos from photographer Petar Kujundzic.
