Jan Gunneweg is very much ‘into wood’. And not just in a tree hugging sort of way. The Dutch industrial designer creates all sort of implausible things from timber. His latest (and greatest) is an all wooden bike. Pretty much everything you see in the photos is made from wood – and that includes the asymmetrical wooden wheels. Tires aside, this thing is 95% wood. And the rest is space age technology. There’s no price on Jan’s website (and it's not in English!), but given the 200 man-hours he spent carving this out of tree trunks it’s not going to be cheap!
