Someone appeared in our village today on a wooden bicycle. Almost inescapably for a bicycle of otherwise conventional ‘safety’ pattern, certain parts were metal — it would be hard to imagine, let alone make, a chain and sprocket transmission out of wood, and wooden head, wheel, and bottom bracket bearings in wood might be rather stiff, though perhaps lignum vitae might work — but frame, front fork etc. were all in laminated wood. The weight felt roughly the same as a normal steel or alloy bicycle. It’s made by a company called Coco-Mat; I’ll put in a picture if I can find one.
