I'm having trouble finding up-to-date information on the growth of cycling in the US and across the globe. How rapidly is the cycling industry growing? In what country is cycling growing fastest? Is the industry growing in lock-step with new cyclists or are established cyclists just purchasing more cycling goods? Where are the most new cyclists hopping on bicycles?
Many questions, I know, and don't expect them all answered. More broadly: Where can I find, or can anyone provide, statistics that demonstrate the trajectory of bike use?
