How Much Does a Mountain Bike Weigh?

If you are looking for a new mountain bike and want to make sure you choose one that is the right weight, it’s important to understand what makes up the weight of a mountain bike and what components are the most important. There are some things that add weight to the bike but may not be needed for your specific type of mountain bike riding. 

Here’s what you need to know about mountain bikes and their average weight.


On Average – How Much Does a Mountain Bike Weigh?

Companies that make mountain bikes are well aware of the effects the weight has on the overall performance of the bike. Cross-country bikes need to be light so they can easily be ridden on long distances and transported when they aren’t being ridden.

The average mountain bike weight is around 29 pounds, with the lightest mountain bike on the market weighing in at 21 pounds. But this weight will vary greatly based on the type of bike you choose to buy. 

Why Do Mountain Bike Weights Matter?

There are many things that determine how well the bike performs and the average weight of the bike is one of them. When you are shopping for a new mountain bike or thinking about adding some extras onto yours, be sure to keep these things in mind.

Effort Required

A heavier bike will be much harder to pedal and need larger wheels. A bike with a carbon fiber frame is very light and therefore easier to pedal. 

Although bikes with aluminum frames are a little heavier, they are also still lightweight.

When you are racing or riding long distances, you don’t want a heavy bike. You want a light bike that allows you to pedal and power it with ease so you can save your energy and ride trails faster. 

A few extra pounds can slow you down significantly and wear you out faster. Lighter bikes are the best option for any type of mountain biking. 

Climbing Ability

It’s pretty easy to coast on downhill bikes, but riding uphill can be a challenge. This requires more effort and is where you exert a lot of energy. 

A lighter bike will be much easier to pedal uphill. Not only will you notice that the lighter bike is easier to pedal, but it will have better traction. 

Downhill bikes can be slightly harder to control if the bike is lighter, but trail bikes and enduro bikes are both easier to pedal uphill when the frame is light.

Downhill Control

When riding trail bikes downhill they can be hard to control. The lighter the bike and the faster you go, the more the bike will wobble and be hard to control. 

That doesn’t mean that you don’t want a lightweight bike. You will just need to remember to control the bike weight so you don’t flip it over. 

The weight of a mountain bike is important but so is the rider’s ability to keep the bike balanced no matter what type of terrain he/she is riding on or the angle or slope he/she is traveling on.

How Much Do Different Types of Mountain Bikes Weigh?

Different types of mountain bikes have different average weights, and if you are looking for a specific type of bike or need your bike to be a certain weight, it is important to know how much each type of mountain bike weighs.

Cross-Country Mountain Bikes

Cross-country bikes have to cover a lot of territory and some steep terrain. They are designed to be the lightest type of mountain bike on the market. 

These mountain bikes need to be able to go uphill easily and also travel downhill with ease. The average weight of a cross-country mountain bike is around 24 pounds.

Downhill Mountain Bikes

Downhill mountain bikes are meant to be sturdy and easy to accelerate as you travel downhill. Because these bikes can also do jumps and hit humps and bumps, they have to be tough so they can withstand this type of riding. 

Therefore, a downhill mountain bike is slightly heavier than your average mountain bike and weighs around 35 pounds.

Enduro Mountain Bikes

Enduro bikes are similar to trail bikes, but they are designed to perform better as the bike descends. They are also designed for the rider to handle the uphill climb as well as tough terrain. 

An enduro bike is also built for speed, as well as to handle the rough terrain. These bikes are made to be sturdy and tough and weigh around 30 pounds.

Trail Bikes

These are made for an amazing performance on all types of terrain. Riders expect these bikes to be able to handle rough roads and bumpy trails. 

The ultimate trail riding bike is made to be durable but also designed to be lightweight so it can be pedaled up and down hills easily. Trail bikes weigh around 29 pounds, which is similar to your average downhill bike.

Electric Mountain Bikes

Electric mountain biking is very popular and great for beginners. These modern mountain bikes are heavy because they have a battery attached to them to assist with pedaling. 

They are easy to ride uphill and take less effort to control and ride. Because of the added weight of the battery, these are some of the heaviest types of mountain bikes available. 

On average, they weigh around 45 pounds.

How Does Suspension Affect Mountain Bike Weight?

Another thing that can have a big impact on bike weight is the suspension. Suspension mountain bike weight can vary, as can the design. 

You get a full-suspension bike as well as hardtail mountain bikes. If you want a lighter mountain bike, you need a lighter suspension. 

The extra weight can make the bike harder to control or pedal, depending on the type of riding you do. The rear suspension is common on XC bikes because they need help staying sturdy on bumpy terrain.

A full-suspension mountain bike may have some extra weight in the front or back. Bike technology has come a long way, and thanks to front-suspension fork designs, even the lightest mountain bikes can have amazing suspension.

Full-suspension bikes and hardtail bikes have very different weights. Hardtail bikes weigh much less and are the lighter option. 

This is because they do not have as many bike components to weigh them down. A hardtail bike can save weight by having a rigid frame and can still be used by cross-country mountain bikers who want to be able to climb easily.

Full-suspension mountain bikes are heavier than other bikes, including your average XC bike, because the full-suspension system adds the most weight to the bike and makes the bike heavy. But some riders don’t mind a few pounds of added weight if it means they have a smoother ride. 

If you don’t want a full-suspension mountain bike because it adds to the mountain bike weight, you can choose the hardtail suspension option. These are common for XC mountain bikes that don’t need full suspension. 

If the bike’s weight isn’t as important to you as the comfort and ride, a full-suspension bike might be the better option. 

How Does Weight Affect Cost?

The total weight of the bike can affect the cost. There are many things that are included in the total weight that also make the trail bike or road bike more expensive. 

Here are some things to consider when determining if a bike is worth the cost.

Bike Frame

The bike frame will affect how much the bike weighs. A carbon frame will be much lighter than most other types of frames, but these frames are also more expensive. 

Keep in mind, the frame is just a small portion of what the bikes weigh, and the way that frame fits with other aspects of the bike is also important. 


Another big part of the bike’s cost is the suspension mountain bikes have. An entry-level full-suspension mountain bike will set you back around $1,500 with some full-suspension mountain bikes costing around $5,000+.


The brakes of a mountain bike can also add to the average weight. Some types of brakes are too heavy for a mountain bike or certain types of bike rides. 

If the mountain bike weighs a lot, it will be harder to stop and need better brakes. The disc brakes only add a few pounds; some of the heaviest mountain bikes on the market have the lightest disc brakes.


When you are mountain biking, you may need some accessories on your bike. Keep in mind even small accessories, like water bottles or holders, can add to the mountain bike’s average weight.

The average mountain bike weight doesn’t include the added accessories, so if you are looking to make your mountain bike lighter, you might want to leave off accessories that are unnecessary. Bike manufacturers may include some small accessories as part of the average weight, but anything extra you add will add to how much the mountain bike weighs.

What to Consider When Choosing a Mountain Bike

When it comes time to choose gravity bikes or mountain bikes for your type of riding, there are a lot of things to consider. 

It is not just about what makes your mountain bike lighter – it’s about what feels right to you and allows you to perform the best on your bike. 

Some of the things that make the mountain biker lighter maybe things that you don’t want or need. So rather try out different types of bikes before you decide so that you can find the one that is the right weight for you.


There are many different types of mountain bikes and each one has a different average weight. While bike weight is an important factor to consider when choosing the right bike, it’s not the only one. 

Keep the weight of the bike in mind when you think about the types of brakes, suspension, wheels, and frame you choose for the bike. The right bike will be easier to control and have better traction on the type of terrain you ride on. 

It will also be easier to pedal when you go uphill and easier to control when you ride downhill.

Choosing the right mountain bike will make your trail rides much more enjoyable and help you perform better.
