The Pros Closet is the largest online retailer of certified pre-owned bicycles in the United States, founded in 2006 in Boulder, Colorado. The company has built a marketplace for buying and selling used bikes by implementing a rigorous inspection, refurbishment, and certification process that gives buyers confidence in the quality and condition of pre-owned bicycles.
Every bike sold through The Pros Closet goes through a detailed multi-point inspection performed by professional mechanics. Bikes are graded on a condition scale and come with a warranty. The platform carries road bikes, mountain bikes, gravel bikes, e-bikes, and triathlon bikes from top brands including Trek, Specialized, Santa Cruz, Cervelo, and Cannondale. The Pros Closet also offers a trade-in program where cyclists can sell or trade their current bikes. The company has helped make premium cycling accessible to more riders by offering bikes at significant discounts compared to new retail prices.
