Biciletle din bambus - se pare ca exista de ceva vreme in tarile sarace dar debia de scurt timp incep sa apara pe piata si sa rivalizeze cu cele mai scumpe biciclete de pe piata - un cadru costa si 3000 lire sterline.

Bamboo bike? Only if you’ve got £3000 to spare
This bamboo bike makes cycling an even more sustainable method of transport. Produced by California-based Calfee Design, the frame is made from bamboo stems hand-picked in the mountains of Taiwan’s Yushan national park (to add to the political correctness of this product, the workers in Taiwan are part of a social project helping local people from disadvantaged backgrounds).
The bamboo is shipped to California where the stems are heat-treated. These are then assembled into a frame and coated in a satin poly-urethane sealant. Lug connections are made from hemp fibre. Each frame requires 2.7m of bamboo and weighs 4-5lb. However, the complete bike weighs 18-19lb.
The basic frame costs £2,175: other parts including saddle and handlebars put the price up to at least £3000. The bike can be purchased at the Eco Age shop in Chiswick, London. It’s necessary to be rich as well as eco-conscious to own a Calfee- only 2 have been sold in London so far. Perhaps National Bike Week (13th - 21st June) will prompt more sales.
Benefits of bamboo:
It grows very fast: some species grow up to 1.5m a day
It supports a greater working load than mild steel without breaking
It does not fatigue like metal (but must be coated with a waterproof sealant)
It absorbs about five times as much greenhouse gas as a ’conventional’ tree plantation
