IRA FLATOW, HOST:
Up next, Flora Lichtman is here with us for our Video Pick of the Week. Hi, Flora.
FLORA LICHTMAN, BYLINE: Hi, Ira.
You went with something Seattlely(ph). How would I describe it - Seattle-like this week for this week's video.
That's right. When in Mayor McSchwinn's city, you have to go with the bikes. Lightening it up for pick of the week, but - as usual.
LICHTMAN: Oh, yes. This week's video is about, not just any bicycle builders, these are folks who are building bicycles out of bamboo.
