LAS VEGAS, Nevada — Bike maker Craig Calfee has found a way to grow bicycle frames in a field, with sunlight and water. He makes them out of bamboo. "It's like bonsai basically," said Calfee, who is based in Santa Cruz, California. "If you grow it inthe shape you want it, it's by far the strongest way to get it in the shape you want it." He's been making bamboo bikes for awhile now, but because each bicycle is made to order, his workshop can turn out only limited numbers of the 2,700 dollar frames.To increase production and improve design, Craig is experimenting with growing bamboo into preformed shapes in the field.
