Oregon based company Resource Revival is keen on sustainable living and the idea that consumers know the origins of the products they buy. Their products are made from used bicycles parts, which bike shops around the USA send to them to be transformed into new products.
Amongst their current designs is this Recycled Bicycle Chain Frame. Like most conventional frames, it can be hung or stood vertically or horizontally, but has the added talking point of being made from old bike chains. It is available in two sizes 4 inches by 6 or 5 x7, which cost $38 and $40 (around £20) respectively.
It can ordered online from the Elsewheres website.
