Mountain Bike Sizing 

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. 

Do You Need a Full-Suspension Mountain Bike?

Determining the necessity of a full-suspension mountain bike hinges on the type of trails you plan to ride, your riding style, and your budget. While full-suspension MTBs excel in rough, technical terrain due to the added rear wheel traction, they're also more expensive and require more maintenance. 

Longer travel MTBs are less energy-efficient when pedaling, particularly on climbs or smoother trails. On the other hand, hardtail bikes are lighter, easier to maintain, and more efficient on ascents and smoother trails, making them ideal for beginners or riders on a budget. Full-suspension bikes also come in a variety of travel lengths. 

Travel is the length of movement the front and rear wheels go through when cycling through the suspension. Short travel bikes will climb better and excel on smooth trails, perfect for XC racing or tame riding. Longer travel bikes are perfect for going fast over rough terrain, racing, and steep descents. In the end, the type of MTB you ride depends on your budget, preferred riding style, and technical ability. Talk to one of our Ride Guides today to help find the perfect MTB for you. 

Women's Mountain Bikes

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. 

Full Suspension Mountain Bikes

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.

Hardtail Mountain Bikes

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. 

Why Buy A Used Mountain Bike

Every single used mountain bike for sale at TPC has undergone a multi-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.
