Pedal Power! E-bikes in China.

Nifty article in The New York Times on electric bikes:

An Electric Boost for Bicyclists
By J. David Goodman (Jan 31, 2010)

"Detroit may be introducing electric car designs and China may be pushing forward with a big expansion of its highways and trains." But millions more are "taking part in a more accidental transportation upheaval."

In China, "an estimated 120 million electric bicycles now hum along the roads, up from a few thousand in the 1990s. They are replacing traditional bikes and motorcycles at a rapid clip and, in many cases, allowing people to put off the switch to cars.  In turn, the booming Chinese electric-bike industry is spurring worldwide interest and impressive sales in India, Europe and the United States. China is exporting many bikes, and Western manufacturers are also copying the Chinese trend to produce models of their own. From virtually nothing a decade ago, electric bikes have become an $11 billion global industry."

Electric bicycle riders in China, where about 120 million such bikes are used, with some going up to 30 miles an hour.

More perspective on e-bikes from other publications:

E-Yikes! Electric Bikes Terrorize the Streets of China (WSJ)
“Electric bicycles, or e-bikes, have taken off in China. But some people say they are dangerous, and may not be so green after all." (Jan 17, 2010)

Bicycles give way to automobiles, but e-bikes keep two-wheel tradition alive. (Dec 14, 2009)

As a bonus, here is an academic paper I came across last quarter doing research for a different class. (Published in Energy Policy:)
