The new wave in bike manufacture is one of the oldest building materials known to humanity - bamboo!
Bike builders say that bamboo has great flexibility and strength characteristics, which mean bamboo can turn into all sorts of bikes, including even high-preformance racers. Now it turns out that someone in Medellin is building bicicletas de bambu. It'll be nice if someone finally starts building hi-performance bikes in Colombia, particularly if they're made from an environmentally-friendly material.
It's being done in Africa. Why not here?
