Mountain bike weight is not an essential concern with weekend riders. However, it is one of the critical factors affecting the mountain riding experience of both novices and experts.

The following article will answer all queries about mountain bike weight. After reading the article, just come back here and see some latest mountain bikes for around $500. Let’s keep reading!

Average Weight of All Mountain & Enduro Bikes

Average Weight of All Mountain & Enduro Bikes

29 – 30 pounds is the average weight of all mountain and enduro bikes. As such, if your mountain bike has a total weight of 30 pounds, it is not too heavy for mountain bikes. According to Hobby Biker, 30 pounds is an ideal start point for beginners.

If your typical mountain bike comes with some added bike components such as a full suspension bike, it might be heavier than the average all mountain bike weight range. In this case, 33-34 pounds is acceptable.

Purchasing MTBs requires knowing many components, not just weight. You can view details of Enduro mountain bikes, then make some purchases if the bikes are suitable to you!

Average Weight of Hardtail Mountain Bikes

28 pounds is the average weight of hardtail mountain bikes. This mountain bike type is designed with front suspension. Thanks to that, it is considered a light bike type for mountain bikers.

Additionally, hardtail mountain bikes are not equipped with pivots or extra tubes, which reduces the weight range of these bikes.

With a lightweight range, hardtail mountain bikes are suitable for climbing hills and riding on smooth terrains.

Average Weight of Full Suspension Mountain Bikes

Average Weight of Full Suspension Mountain Bikes

The average full suspension mountain bike weight range is from 30 pounds to 34 pounds.

Why are these bicycles heavy? In addition to the front suspension, the rear suspension and other bike components will add a few extra pounds to the final weight of a full suspension mountain bike. Along with that is the specific frame geometry holding the rear suspension and resulting in heavy weights.

Although these full suspension mountain bikes have added weight, they are the most versatile and comfortable type of mountain bike. Thanks to the rear suspension, these mountain bikes are well suited for riding on rugged terrains like the lumpy trail.

Average Weight of Cross-country (XC) Mountain Bikes

The average weight of Cross-country mountain bikes is around 20 – 25 pounds. This option is the lightest mountain bike on the market.

These bikes are lightweight because they are usually made from carbon or aluminum frames. These two materials are not only durable but also very light. In addition, XC mountain bikes have no suspension. It also reduces weight.

Thanks to the lightweight design, cross-country mountain bikes are ideal for long-distance mountain bikers.

Average Weight of Downhill Mountain Bikes

Average Weight of Downhill Mountain Bikes

The average weight of downhill mountain bikes is about 35 pounds, making this bike type the heaviest option.

When going downhill, the bike will absorb a much more significant impact compared to riding on other terrains. Therefore, they need to be designed to be sturdier and heavier. In this case, heavy downhill bikes also help the bike go faster.

Downhill bikes are equipped with specialized components that make them heavier than other mountain bikes.

The frame increases the weight of the downhill mountain bikes. These models often have to handle steep ramps or even heavy jumps. Therefore, manufacturers must choose the most durable and most robust frame materials.

Light materials like carbon fiber are not preferred in downhill mountain biking. Instead, this mountain bike type frame is made of more potent and heavier materials such as aluminum alloy, steel, and even titanium.

Main contributors to Mountain Bike Weight

There are four components considered significant contributors to mountain bike weight. They are the wheel system (front and rear), the frame, the fork, and the drivetrain.

According to Bostonbikes, these four parts account for 67% of mountain bike weight.

Wheels – 33.6% of mountain bike weight

Wheels – 33.6% of mountain bike weight

The front and rear wheels are the heaviest components, contributing about 34% of total weight.

Wheels are the most essential part of a mountain bike. They are in direct contact with the ground and are subject to all the braking force of the bicycle.

During mountain biking, the entire weight of your body will also be on the wheels. Therefore, they need to be designed with enough weight to support you.

On fat bikes, the wheels contribute even more weight to these bikes. Big and wide wheels can add up to 3-4 pounds to the fat mountain bike’s overall weight.

Fork – 14.85% of mountain bike weight

The fork is the second heaviest part of a mountain bike. It accounts for about 15% of the mountain bike weight. This figure does not include the handlebars and stems.

Frame – 11.38% of mountain bike weight

Frame – 11.38% of mountain bike weight

Coming in the third position is the frame, which contributes about 11% of mountain bike weight.

Why does the seemingly largest and heaviest part take up so little weight? The answer is because it is usually made of lightweight materials and designed with a hollow structure.

The lightest material of the mountain bike frame is carbon fiber. It is followed by titanium, aluminum, and steel. Aluminum is the most common frame material among these materials since it is light but durable enough for challenging terrains.

Drivetrain – 7.14% of mountain bike weight

Drivetrain separately adds more than 7% to the total weight of a mountain bike. This percentage does not contain the chain weight, which accounts for 2.5% of mountain bike weight.

Why Mountain Bike Weight Important

Mountain bikes have to handle complex terrains like bumpy and steep trails. Therefore, they need to be sturdier and more stable. That adds weight to them.

During downhill mountain biking, a heavy mountain bike is an advantage helping them descend faster. Moreover, the added weight from weight and suspension will assist these bikes in handling challenging terrains.

Why Mountain Bike Weight Important

By contrast, lighter is better in the case of cross-country mountain bikes. These bikes are designed for those who chase speed and distance. Thus, they are designed to be as light as possible for cyclists to maximize the pedal performance.

For female mountain biking, bike weight plays a vital role in their riding experience. Women have a lower average height and weight than men. Therefore, a light mountain bike will be easier to control and more agile on challenging roads.

How to Make Mountain Bikes Lighter?

To cut off the unnecessary weight of a mountain bike, adjusting and upgrading the heaviest parts of the bicycle are the best solutions.


How to Make Mountain Bikes Lighter

Wheels are the largest weight contributors of a mountain bike. You can apply some methods to reduce weight in wheels. Here they are:

  • Upgrade bike wheels:

Pre-assembled wheels are often poorly machined and made of heavy (which also means less expensive) materials.

You can replace them with high-quality wheels at a bicycle accessories store. A new pair of wheels will help you increase cycling performance and save weight.

  • Use tubeless tires:

Getting tubeless tires is another way to make your mountain bike lighter. Using tubeless tires can help you reduce from 150 grams to 650 grams of the total weight of the mountain bike. It is not a large number but enough to make a difference.

Use tubeless tires

  • Use lightweight inner tubes:

If tubeless is not your favorite taste, you can choose inner tubes made of lightweight materials like latex. Latex is the lightest tube material, which has an average weight of only 75 grams.

  • Choose smaller wheel sizes:

The wheel size is another factor determining the bike weight. To reduce weight, you can get 26 inches or 27.5 inches wheels instead of 29 inches wheels.

So, having an appropriate wheel for your MTBs is the key for weight reduction. Top 11 best mountain bike wheels in 2021 is where you can look for high-quality MTB wheels.


You can adjust some components in the fork to save a few extra pounds

You can adjust some components in the fork to save a few extra pounds.

The first thing you can do is remove the chain device. Nowadays, there are other replacements for chain devices. For example, you can use SRAM rings to cut off the fork weight and mud collection.

Secondly, Consider the length of the stem. Do you really need a long stem? If the answer is no, you can altogether remove this part to save between 100 grams and 200 grams in weight.


A mountain bike with a carbon fiber frame will be your lightest option. In fact, you cannot change the weight of the bike frame. So if a lightweight bicycle is your goal, choose a carbon frame from the start.

A paint-free is also a light option for mountain bikers. According to Paint My Bike, the paint frame can weigh more than 200 grams.

In addition, you can also remove unnecessary parts such as the water bottle cages, phone holder on the frame to make the mountain bike lighter.


you can start with a 1x drivetrain to have a lighter mountain bike

Instead of purchasing a 2x or 3x drivetrain, you can start with a 1x drivetrain to have a lighter mountain bike. The 1x setup weighs only about 2000 grams. Meanwhile, 2x chains have an average weight of up to 2400-2500 grams.

Seat post

You might think that a dropper seat post is better than an aluminum alloy seat post. It’sIt’s true in terms of flexibility. However, if weight is your priority, an aluminum alloy seat post will be the better option.

Dropper seat posts have an average weight of 600 grams, weighing twice the average weight of the aluminum alloy component.


Although pedals are not a significant contributor to your mountain bike weight, your pedal selection can help you cut some weight.

Instead of choosing metal pedals, you can ultimately use plastic pedals. In addition, clipless pedals are also lighter in weight on average than flat pedals.

Regular cleaning

Regular cleaning

Another way you should apply to make your mountain bike lighter is to clean it regularly. Mud, dirt on wheels, frame, and chain also cause your bike to be heavier.
