Antoine Lecuirot, founder of the To Diffusion store, rides an electric bike in Paris, July 25, 2008. When the store first opened in 2003 few people here had heard of electric bikes and turnover was mainly electric scooters. But in 2004, Lecuirot says the tide changed and now 80 percent of his revenue is from bikes, whose sales increased 70 percent in the year to March.
