Decathlon has adopted its business model to work in 48 wildly different countries on five continents in some 1,600 stores — but is just starting in the U.S. With global bike sales estimated at $2.2 billion in 2018, it is arguably the world's largest bicycle retailer on a revenue-basis, moving some 4.5 million bikes annually, and outfitting more cyclists in its private-label bike clothing than any other brand.
