to be used.
Shop the largest inventory of the best used mountain bikes for sale with TPC! From XC hardtails to full-suspension trail and enduro bikes, we have the perfect used MTB for every type of rider.
Find XC and trail hardtails that are budget performers. They provide efficiency and simplicity for endless laps with less maintenance. Or if you prefer, full-suspension MTBs provide extra comfort and confidence to tackle rougher and gnarlier trails, whether you’re deep in the backcountry or shredding at the downhill bike park. Looking for new adventures? Try a fat bike or an electric mountain bike (E-MTB). TPC carries hundreds of used mountain bikes from top brands like Trek, Specialized, and more.
Mountain bikes use lettered sizes, ranging from XS to XL. Wheel size (27.5" / 29") also affects fit and ride quality. If you're looking to buy a used MTB make sure you find the correct fit to get the most out of your ride.

Each brand measures its bikes differently, so check our sizing guide for info on the best fit and geometry. Still not sure? Chat with a Ride Guide on your specific fit per brand.
What’s the difference between women-specific and unisex MTBs? Not much actually. Women-specific bikes might have women-specific components like smaller grips and women-specific saddles, and the suspension might also be tuned for lighter riders. But any mountain bike can be adjusted to fit your body, and finding the right bike to fit you perfectly is easy with TPC. Check our women’s bike buyers guide for the deets. If you're looking to buy a new or used women's MTB for sale, chat with our ride guides for the best options.
Whether you want a big travel enduro bike, a do-it-all trail bike, or a lightning-fast XC bike, TPC has new and used full-suspension mountain bikes for sale to fit your needs. Bikes with rear suspension improve comfort by taking the sting out of rough terrain and improve performance by increasing traction and your ability to absorb hard hits out on the trail. Take on the gnarliest descents or an all-day cross-country epic; the choice is yours.
From cross-country racers to downhill specialists, there is a hardtail made for every type of rider. With no rear suspension, hardtails are more affordable and use fewer moving parts, so they’re cheaper and easier to maintain.
Choose a lightweight carbon hardtail with a 100-120mm suspension travel fork for XC racing. If you’re more interested in fun than racing, trail hardtails like the Kona Honzo are the ultimate quiver-killer machines. For gnarlier terrain, hardcore hardtails with long travel forks and slacker geometry let you plow through the roughest trails.
Every single used mountain bike for sale at TPC has undergone a 141-point inspection by a professional mechanic to ensure it rides like new. We replace damaged or worn parts, service the suspension, and test-ride before shipping to make sure everything works perfectly.
At TPC, we stand behind our service, inventory, and shipping processes with a 100% 30-day money-back guarantee. If your bike doesn’t meet your expectations or the fit isn’t quite right, there’s no hassle. Return the bike and get your money back. Period.
