Bikes on BBC

I ran across an interesting audio segment from the BBC on bicycling in the modern world.

From their description:

"This three - part series illustrates how the bicycle is used today and what impact it has on people's lives.

With more than a billion models worldwide, the bicycle has found a place in every society.
Since its invention in 1817 people have redesigned and used the bike for hundreds of different purposes.

From sporting events and policing the streets to sharpening knives and selling ice cream.
Using a lot of leg power, the Bicycle Diaries journeys into three different places around the world to discover the communities and people for whom two wheels are better than four. "
