quote from article:

"It would also be interesting to compare the aerodynamic drag of this frame with traditional tubed frames in the wind tunnel (I think this frame would have a lower coefficient of aerodynamic drag)..."

is he kidding?

novel design, but I'm pretty certain that this frame would grap gobs of air

That frame he made from bamboo shoots filled with poly foam is amazing. I want one!

Can anyone say turbulent flow?

Sorry, I'm an engineer.

Calfee design is working on producing Bamboo cargo bikes in Africa. From the stuff I read it's a really cool idea that could help a lot of people out.

According to Craig Calfee, yes.

Back in 1984, when Craig was wandering around Africa, he noticed three things: 1. There was a lot of bamboo, 2. People used bikes and didn't have enough of them, and 3. they needed jobs. Perhaps people could build their own bamboo cargo bikes. So he put a small notice on the website to see if someone wanted to fund a trip to Africa to see what it would take to get the idea rolling. The Earth Institute at Columbia University decided it was worth trying, so off we went! Craig determined that it was possible and proceeded to set it up. Media attention on the idea was phenomenal!

The axel-less front hub is pretty cool:)
