The air-purifier bike designed by Bangkok's Lightfog Creative & Design Company currently exists only in concept.
In theory, its aluminum frame would run on a "photosynthesis system" that generates oxygen through a reaction between water and electric power from a lithium-ion battery.
"We want to design products which can reduce the air pollution in the city. So we decided to design a bike because we thought that bicycles are environmentally friendly vehicles for transportation," creative director Silawat Virakul told FastCoExist.
"Riding a bicycle can reduce traffic jams in a city. Moreover, we wanted to add more value to a bicycle by adding its ability to reduce the pollution," Virakul said.
