In this article, I will answer the question “how much does a mountain bike weigh” and how weight is a major factor in a bike’s performance.
A lot of mountain bikers take the weight of their bikes very seriously. While others just don’t care that much. Whichever the case is, it’s a known fact that there are multiple disciplines in mountain biking and each of them has their own design and weight.
What is the Average Weight of a Mountain Bike?
Mountain bike manufacturers have been evolving bikes and making them as light as possible. This has made the average weight of a modern mountain bike into around 13 kg or 29 lbs.
Though the weight of the bike has been shifting with the new components being much heavier compared to other parts, such as frames and forks getting lighter.
Why Does Weight Matter on a Mountain Bike?
Weight matters as it can impact the performance of the bikes. Manufacturers have even resorted to using carbon to shave as much weight as possible.
With each type of mountain bike having its own kind of discipline, it’s necessary for them to have their own average weight in order for them to perform properly.
Less weight means it’s easier on the climbs, while more weight allows it to perform at its best on descents.
Energy consumption decreases the lighter the bike gets. This means that when the mass increases, then more work is needed for the rider to move the bike. They also have to pedal harder to increase their speed.
The rider needs to pedal with more power to move forwards. This factor matters in climbing as you need a lot of power to go uphill faster.
Cross country bikes have changed their geometry and construction. This is so that their bikes become more lightweight and become optimized for climbing.
Enduro and downhill mountain bikes need more weight to become stable when they’re going downhill. The bike performs much better, and the rider can have more confidence in the descents with a heavier bike.
This extra weight added to their race machines allows them to have better handling when hitting technical courses at high speeds.
Different Types of Mountain Bikes and their Corresponding Weight
Trail bikes are all-around mountain bikes designed to take on steep climbs while also being able to perform on rough descents. They weigh 13.2 kg or 29 lbs, meaning that they’re meant for performing on any kind of terrain.
Although this bike has its own limitations because of how its performance isn’t optimized on climbs or descents, but only to perform both.
A cross country mountain bike is designed to be as light as possible for it to complete long and steep climbs. It’s used for fire roads and mellow descents, so it doesn’t need the sturdiness of a downhill bike.
The average weight for this is around 10.8 kg or 24 lbs, making it the lightest type of mountain bike.
Downhill bikes are optimized to go on any kind of technical descent at top speeds. They are designed to be the sturdiest type of bike to prevent it from breaking due to heavy impacts from jumps and drops.
This gives the downhill bike an average weight of 15.8 kg. or 35 lbs. because of the longer suspension and sturdier linkages.
Electric mountain bikes
E-mountain bikes are designed with a battery attached to it to help the rider finish any kind of steep climb. It makes pedalling much easier for them, finishing climbs without breaking a sweat.
With the added weight of the battery and other electrical components of the bike, it has an average weight of 18 kg. or 45 lbs.
An enduro mountain bike is almost the same as a trail bike. But it’s more optimized on the descent. Its geometry is also closer to a downhill bike. The bike is made for the rider to handle climbs, but it’s more focused on traveling fast on rough and technical downhills.
This makes the bike much sturdier and heavier with an average weight of 15 kg. or 30.9 lbs. This already includes the heavier components that they are equipped with.
Hardtail vs Full Suspension Mountain Bikes: Weight Difference
A hardtail is much lighter compared to a full suspension bike because of the absence of the rear shock and linkages. This makes this bike a popular choice for cross country riders because of how light it is.
With the rigid frame and lesser weight, it makes it easier for them to conquer steep climbs at a faster rate.
Top Three Best Lightweight Mountain Bikes Under 10 kg.
- Specialized S-Works Epic AXS HT – The most lightweight bike that’s around. This cross country bike only weighs 8.6 kg. as equipped with some of the lightest components available in the market. It’s a hardtail carbon mountain bike that specializes in going fast while being able to easily finish steep ascents and mellow descents.
- Orbea Alma M-Ltd – This 8.7 kg.-mountain bike goes fast on races with its rigid design, which means it doesn’t have any suspension. Though this doesn’t mean that it can’t go on trails, the Orbea Alma M-Ltd is designed to still feel smooth on rough terrain.
- Mondraker Podium Carbon RR – The Mondraker Podium Carbon RR weighs only 8.9 kg. and is made to conquer steep climbs while still being able to go fast on descents. This hardtail cross country bike uses forward geometry, which is designed by Mondraker to have a more aggressive stance during descents.
Who are the “Weight Weenies”?
Weight weenies are bikers who love to decrease the amount of weight on their bikes as much as possible. These types of riders are road or cross country riders who need their bikes to be light as they need less power to pedal so they can conserve more energy.
High-end vs Budget Mountain Bike: Seeing the Weight Difference
There’s an enormous difference between the weight of a high-end mountain bike compared to a budget mountain bike. The parts used by high-end mountain bikes are very expensive due to the materials used being lighter and sturdier.
Manufacturers use the best type of material in order for the riders to have a better performing bike.
Budget mountain bikes contain low to mid-level parts. They sacrifice the weight by using cheaper materials to lower the price to allow the general consumers to afford them.
How Much Does a Mountain Bike Weigh: Conclusion
Weight is important for a mountain bike’s performance. The lighter the bike is, the better it performs because of how nimble the bike becomes.
Although it will also depend on the discipline as each kind of bike has heavier components in order for it to become sturdier, more durable, and more capable in handling rough terrains.
