9 Things to Consider Before You Buy a Mountain Bike

Though every mountain biker is different, there are several top priorities to consider when buying a new bike, says Earl Walton, global director of training and coaching at IRONMAN.

1. Terrain

"Typically, for mountain biking, the choice of bike is less about the skill level and more about where you plan to ride," says Walton.

"Are you riding in a mostly flat area that has a few roots and ruts, mixing pavement and gravel or are you jumping in a chair lift at the local ski resort? Mountain bikes are made for specific types of terrain or disciplines. Check out the local trails and get to know them a bit. Go for a hike or a run and get to know your area. This goes a long way to defining the type of bike you want."

2. Bike Type

If you're a beginner, you'll likely want to consider a trail or cross-country bike, since they're incredibly versatile and can help you get comfortable with a wide variety of terrain types.

Cross-country​: Cross-country bikes are made for racing speed, agility and responsive bike handling, but they're also a good fit for beginners wanting to play around.

Trail​: These all-purpose bikes can do it all, whether you want to casually ride singletrack or send it downhill. They're incredibly versatile and can help beginners get comfortable with a wide variety of terrain types.

Enduro​: Enduro bikes are good for racing, but they're also handy for any situation in which you want to go fast, both uphill and downhill.

Downhill​: These bikes are specially designed for bike parks and downhill races, with big cushiony suspension (often full suspension) and long wheelbases.

3. Suspension Level

Just like a car, a mountain bike comes with varying levels of suspension, or the system designed to absorb shock and give you a smooth (or bumpy!) ride.

Full suspension:​ As the name suggests, full-suspension bikes are designed for maximum shock absorption. Full-suspension models typically feature shock absorbers on the front and rear of the bike. Full-suspension bikes are usually among the most expensive (and heavy) bikes. They can also be more difficult to maintain.

Hardtail​: Hardtail bikes have front suspension only — there's no shock absorption on the rear of the bike. These bikes tend to be more affordable, lighter and easier to maintain.

"In the simplest terms, a hardtail can handle just about anything with the right amount of skill and will feel stiffer for climbing or longer flatter riding," says Walton. "'The full squish' is just as it sounds, super comfy and can tackle the rougher terrain. I like the full suspension for my trail riding as I find it to be a bit more comfortable and sometimes a bit safer when it comes to tricky spots. That said, it also comes with a bigger price tag and can be sluggish on flatter terrain."

If you're just starting out, go with a hardtail bike — you can always upgrade to full suspension later as you get more into the sport.

4. Fit and Sizing

The bike that works for your super tall best friend won't work for you, and vice versa. You need to find a bike that's appropriately sized for your body — more specifically, your height. Mountain bikes typically come in four sizes, all based on the height of the rider: small, medium, large and extra-large.

"A bike that does not fit you makes riding uncomfortable at the very least, but can also make it dangerous," Walton says. "Remember that you are up for an adventure, so your bike should be an extension of yourself and your skills. A perfect fit will lead to a perfect ride."

5. Frame Material and Weight

You also want to consider the bike's frame, which is typically made of two main types of materials: aluminum alloys or carbon fiber.

There are pros and cons for both materials, but generally speaking, carbon fiber tends to be more expensive, lighter and stiffer. Aluminum alloy frames are cheaper, but they're also heavier.

Both materials are durable, though as an added bonus, many bike manufacturers offer some type of warranty, too. Choosing the right frame material boils down to what you want to spend and the type of riding you love.

6. Wheel Size and Tire Type

There are two main mountain bike wheel sizes for adult riders: 27.5 and 29.

You'll choose the wheel size based on what you hope to get out of your bike — generally speaking, 27.5-inch wheels are lighter and they accelerate faster, which can make your bike feel more responsive and snappy.

The larger 29-inch wheels tend to have better traction and are more efficient on longer rides; they can also make it easier to roll over objects you might encounter, like rocks, boulders, tree roots and other features. Since the 29-inch wheels are larger, they're generally better suited for taller riders, too.

No matter your wheel type, know you don't have to be committed to one tire type forever. Just like with your car, you can switch and upgrade your mountain bike tires depending on the type of terrain or riding you love the most. Tires are designed with specific features in mind, including grip, speed, control, weather and trail material.

"We're talking knobby, fatter tires that grip the trail and hold a line," Walton says. "Quality tires are important no matter where you ride, but you will also be met with an array of wheel sizes."

7. Gears

All bikes, including mountain bikes, feature gears that can help you optimize each stroke of the pedals. The more gears on your bike, the more choices you have when you're climbing uphill or cruising back down. The higher the number of gears, however, the more things that can go wrong and need to be repaired.

"There definitely was an old-school mindset of the more gears, the better," says Brandon Slate of Rocky Mountain Outdoor Center in Buena Vista, Colorado. "But 'derailleur is failure' and those things break. They can be expensive and time-consuming to maintain."

8. Saddle Design

The mountain bike saddle, aka the mountain bike seat, can make a huge difference in how comfortable your rides are. There are bike saddles made especially for male and female pelvic structures, as well as saddles that can relieve pressure, help reduce chatter and keep you cool.

"You spend hours on it, so comfort is super key," Slate says.

On a related note, your mountain bike may feature a dropper seatpost, which is a special mechanism that lets you quickly adjust the height of your seat. These can be handy especially as you advance in the sport.

"It helps you put your body in the right anatomical position to perform whatever skill," Slate says.

9. The Fun Factor

Finally, don't forget that mountain biking is all about having fun. If a bike doesn't excite you, move along and try something else.

"This is my rule with any and all new equipment," Walton says. "Does it make me want to get up in the morning and go? Buy the bike that excites you — after all, you're buying a mountain bike, not a new desk. You should get a thrill just thinking about your next ride."
