What size mountain bike should I buy?

If you’re looking at buying a new mountain bike, it’s important to consider what kind of riding you’ll be doing. If you plan on spending most of your time on smooth pavement or paved trails, then a smaller sized bike may work better for you. However, if you plan on exploring rugged terrain, then a larger sized bike might be more suitable.

What If I Got My Mountain Bike Size Wrong?

If you bought a mountain bike online without trying it out first, there’s no way to tell whether you got the right size. To avoid this problem, try these steps:

First, check the manufacturer’s sizing chart. This will show you how many sizes are available for each model.

Next, compare your measurements with the manufacturer’s recommendations.

Finally, take your bike into a local store to make sure it fits properly.

Mountain biking is a sport that requires proper equipment to enjoy all its benefits. However, finding the right gear can be difficult. Here are some tips to make sure you find the best mountain bike fit for your body type.

1. Know What Type of Riding You Want to Do

Before buying anything, it’s important to understand what riding style you prefer. Are you looking for comfort, speed, or both? How much weight do you plan to carry? These questions will help you narrow down your search for the perfect mountain bike fit.

2. Consider Body Size

Body size plays a huge part in determining the best mountain bike fit. For example, shorter riders may benefit from longer seat posts and smaller handlebars. Larger riders may require shorter seatposts and larger bars.

3. Measure Yourself

Once you know what kind of riding you want to do, you’ll need to measure yourself. While you can buy a tape measure, a ruler, or a protractor, a simple measuring stick is easier to use. Simply place the stick along the centerline of your back and mark the spot where your shoulders meet your hips.

4. Check Your Stem Length

Next, look at your stem length. There are several different options when it comes to stems, including drop, rise, and reach. Drop refers to the distance between the bottom bracket and the saddle. Rise refers to the height of the front end of the bike above the ground. Reach refers to the distance between your hands when standing next to the bike.

5. Choose Your Frame Shape

After measuring your frame, choose the shape that fits your needs. For example, if you’re tall but short, you may want a slimmer frame. If you’re short but wide, you may want a wider frame.

6. Look for Features

Finally, consider features like suspension forks, disc brakes, and rack mounts. They’ll give you extra control over your ride.

7. Test Ride Different Models

Once you’ve narrowed down your choices based on your measurements, test ride different models until you find the one that feels comfortable.

8. Buy the Right Gear

Now that you’ve found the perfect mountain bike fit, it’s time to shop! Start by choosing the right components. The following list includes common items that every mountain biker should own.

  • Helmet: Helmets protect your head during crashes. Make sure yours has EPS padding and an adjustable strap.
  • Gloves: Gloves keep your hands warm and dry while riding.
  • Boots: Boots provide traction and protection against sharp objects.
  • Saddle: Saddles offer support and cushioning.
  • Tires: Tires provide grip and stability.
  • Spokes: Spokes allow you to adjust tire pressure without tools.
  • Handlebar: Handlebars let you steer with ease.

When shopping for a new bike, you may wonder what size you should get. The answer depends on your body type, as well as where you ride.

To figure out what size bike you need, start by comparing your body type with the following descriptions. Then look at the bike’s frame size and adjust accordingly.

Body Type:

Your body type influences the amount of weight you carry, so you’ll want to match this to the bike’s frame size.

Frame Size:

Frame size refers to the distance between the front axle and the rear axle. It determines how wide the bike is. Larger frames are easier to handle and more stable. Smaller frames are lighter and faster.

Once you’ve determined your body type and frame size, you can choose an adjustment option based on your needs.

Seatpost Length:

This option adjusts the distance between the bottom bracket and the top of the seat post. Longer posts provide greater stability and control. Shorter posts offer more maneuverability.

Handlebar Drop:

With this option, you can raise or lower the handlebars.Raising them makes the bike easier to steer and increases its stability. Lowering them makes the bike easier and quicker to turn.

Bar Height:

With this option, you can move the bars up or down. Moving them higher gives you a more upright posture, making the bike easier to balance. Lowering them makes it easier to shift gears.

Pedal Position:

Adjusting the pedals changes their angle relative to the crank arms. Raising the pedals raises the crank arms, making the bike easier and more comfortable to climb hills. Lowering the pedals lowers the crank arms, making it easier to accelerate.

How to measure your inseam

Mountain bikes come in all shapes and sizes. To find the right size for you, start by measuring your inseam (the distance from your crotch to the ground). Once you know your inseam, consult the bike size chart below to find the right bike frame size (either mountain or road).

Keep in mind that the chart is a general guide. If you fall on the borderline between two sizes, it’s better to err on the side of caution and choose the larger size. You can always adjust the seat and handlebars to fit your body. And, when you buy a bike from REI, we’re happy to help you fine-tune your fit before you take your new bike out on the trail.

Mountain bike sizing for XC

When shopping for a mountain bike, the first step is to figure out what size you need. Mountain bikes are sized based on the length of their seat tubes, which is the distance from the center of the bottom bracket to the top of the seat tube. The standard size for a mountain bike is 26 inches, but there are also sizes available in 27.5 inches and 29 inches. You can determine your mountain bike size by your height using the chart below.

If you are between sizes, it is generally better to go with the larger size. This will give you more room to grow into the bike and make it more comfortable to ride. If you have any questions about what size mountain bike you need, please feel free to reach out to our team of experts for help.

Mountain bike sizing for Trail

Mountain bike sizing is generally calculated based on the rider’s height. However, there are other factors to consider when choosing the right size mountain bike. If you’re riding primarily on trails, you’ll want a bike that’s designed for that terrain. Here are some things to keep in mind when sizing a mountain bike for trail riding:

  • The rider’s height is the starting point for mountain bike sizing, but it’s not the only factor to consider.
  • Every brand has slightly different dimensions for each size bike, so it’s important to test ride before you buy.
  • Frame geometry plays a big role in how a mountain bike handles, so pay attention to that when choosing your size.
  • The tires on your mountain bike also affect how it rides, so keep that in mind when making your choice.
  • Ultimately, the best way to find the perfect size mountain bike is to test ride as many bikes as possible.

In order to find the perfect mountain bike size, it is important to take into account the type of bike you are looking for.
