Phil Bridge, a Product Design student at Sheffield Hallam University in UK came up with a bike made with paper cardboard. According to BBC, the only non-paper parts are the wheels and the chain. But from the video it looks like the spoked disc is also metallic; maybe that’s part of the “chain”. In any case, this is one cool invention. It is hoped that by sharing this cool video by BBC widely that more people would be inspired to come up with ever more surprising and ingenious eco-friendly inventions for every aspect of our living that could contribute greatly to the protection of our environment and Mother Earth, so that our children and future generations will think fondly of us the predecessors rather than hate us for destroying their living environment.
