Bike Europe reports in U.S. e-Bike Market Takes Off that the electric bike market in the U.S. is growing despite the financial crisis.  The article reports:

Amidst the financial crisis the US bike market and in particular the e-Bike segment is doing business very well. Reports say that the number of e-bikes sold in the U.S. is expected to reach a record 170,000 units this year as big retailers get in on this fast growing market.

While much of the growth is through big box stores, any increase in electric bike usage is a good thing for the economy and environment.  Plus, as more people use electric bikes, independent bicycle designers such as EcoBike get a push from people who want higher quality products with better service and warranties.
