There are no surprises here. Every pre-owned bicycle we sell is serviced, inspected, and rated. Wear items — such as chains, brake pads, and tires — are replaced if they have less than 50 percent life.

Beyond those consumables, the condition chart above shows you what to expect. To create every chart, our experts inspect each bike and rate its components on a scale of 7-10. The Overall Rating is the average of those individual components, helping you tell how much overall wear this bike has. What about bikes rated 1-6? It’s simple. We don’t sell anything that scores below a 7. You’ve got high standards, and we do too.

Along with the condition chart, look closely at the bike’s detail images, which will highlight any wear or damage. Learn more about how we rate a bike’s condition to create this chart.
