There are a number of bamboo bikes already on the market so they and the BBC are a bit behind the curve.
e.g
Calfee,
Raw,
Organic Bikes etc
There's always someone thinks they've invented the next great thing in bikes, when actually, they are about 5/10/50/100 years too late.*
I'd love one, they apparently ride beautifully.
Craig Calfee is also involved in the
Bamboosero project in developing countries.
*I was parking my 8spd hub geared winter hack outside Sainsburys when an old chap came up and said "Is that a hub gear?" "yes", I said, and he proceeded to tell me how he'd had a bike with a Sturmey 3 speed and had worked out that you probably make a hub gear with up to 5 spds nowadays. I didn't have the heart to tell him about Rolhoff...
