Fat Bike Vs Mountain Bike – Which bike is better

Both Fat Bike and Mountain Bikes have their strengths and weaknesses. With the rise in the popularity of fat bikes, there has been a corresponding increase in riders looking for advice on which bike is better. As a result, the fat bike vs mountain bike debate has been raging for years with no victor.

The truth is that it’s difficult to say which bike is best overall because both types are good at different things. The right decision depends on what you want to do with your bike.

To help you make a decision, I’ve compiled everything you need to know, including detailed pros and cons, so you can see what each bike type offers.

Fat Bike vs Mountain Bike – Which is Better and Why

In this section, we’ll first look at a brief overview of each type of bicycle.

Fat Bike Overview

A fat bike is a bicycle that has oversized tires, usually 3 or 4.5 inches. They were originally designed for use on soft terrains like snow and sand and in areas with limited traction, such as beaches and bogs.

The wider the tire, the more stable the bike feels on top of softer surfaces such as snow, sand, and mud so riders can use them without having to worry about sinking. Nowadays, people are using them more for mountain biking and even commuting because they can handle a variety of terrains just as well as a mountain bike.

Fat bikes are not the fastest bicycles out there, but they’re great for more relaxed rides in flatter areas. They feel stable with their wider tires and make it easy to ride over all terrains — even if there is a lack of traction!

Pros of a Fat Bike

  • A fat bike is a more affordable bicycle option.
  • Great for more relaxed rides.
  • They are versatile, great for commuting and mountain biking.
  • Fat bikes can be ridden in all conditions, including surface areas with limited traction.
  • Fat Bikes are excellent for bike touring.
  • They offer a very comfortable ride through bad terrain.
  • The weight limit of fat bikes is generally higher on average.

Cons of a Fat Bike

  • Fat bikes are slower than mountain bikes in general.
  • They are heavier than MTBs.
  • The tires make them have more rolling resistance on smooth pavements.
  • They’re not as stylish.
  • You might not ride them as much since they are big and bulky.
  • Fat bikes are harder to ride over hills.

Mountain Bike Overview

how much does a mountain bike weigh

Mountain bikes were developed to handle off-road riding conditions such as rocky terrain or single-track trails, hence its name. These bicycles tend to have a lighter frame, making them lighter overall while still being sturdy enough to handle the extra weight that comes with 2.5 inch wide knobby designs. The knobby or ‘studded’ tires attached to these frames are designed for off-road use and can provide grip when needed as you navigate corners, hills, and obstacles.

Mountain bikes are also more expensive than fat bikes because they’re better quality and have many specialized parts that make them ideal for off-road rides.

Thanks to their suspension systems, you can go on long mountain bike rides with less stress on your body corners. The frames are built very sturdily, so you can take on any terrain type at high speeds without worrying about being uncomfortable or getting injured.

Pros of a Mountain Bike

  • Mountain bikes are well-built, which means they will last longer.
  • Mountain bikes are good for off-road use.
  • Quality frames make it safe to ride on any terrain at high speeds.
  • They are comfortable to ride and allow you to ride longer distances with less stress on your body parts.
  • Mountain bikes can be used for various situations from bike touring, commuting, Cross Country(XC), downhill, etc.
  • They feature Better suspension systems and quality than fat bikes overall.

Cons of Mountain Bikes

  • Because mountain bikes allow you to take on rough terrain faster, they can be considered more dangerous for some riders. 
  • They’ll be more likely to get stolen
  • Mountain bikes are extremely expensive in some instances.
  • They aren’t the best for commuting.

Comparing By Feature

To give you a clearer picture of the differences between mountain bikes and fat bikes, I’ve compared them by the Key features of durability, price, weight capacity, design, and drivetrain.


Mountain bikes are designed to take on rugged terrain that is difficult for other types of bikes. The mountain bike has a tougher frame which is designed to withstand impacts from the trail. There are many different frame designs for mountain bikes, and they are suitable for different activities. For example, XC MTBs are good for touring or commuting. Downhill bikes seemingly have a more dirt-bike-like geometry, and hardtails do not have suspension like a full-suspension bike.

On the other hand, Fat Bikes tend to have a hardtail style frame design, with the only difference between the types of fat bikes being the drivetrain.


Both the mountain bike and fat bike feature a variety of different drivetrain configurations. The fat bike comes with an electric, single-speed, or multiple-speed drivetrain. Similarly, a mountain bike can feature an electric-powered motor or multiple-speed drivetrain. However, mountain bikes don’t come with a single-speed variant unless it is custom-built.

Weight Capacity

Mountain bikes and Fat bikes offer the highest weight limit of most normal bicycles. They both have an average weight limit of 265 pounds to 300 pounds.


The durability of either type is subject to the type of components the manufacturers used to design them. With that in mind, you can expect that you can have either option around and in operation for the entire lifespan.


The Fat Bike is cheaper than a Mountain Bike when compared to the features offered. Most fat tire bikes will fall within the $200 – $3000 range, while Mountain bikes can be found for as cheap as $300 up to $19,000.

What are the main differences between a Fat Bike vs Mountain Bike?

The main difference between a fat bike and a mountain bike is the tires. A fat bike has larger tires, making it better on softer surfaces like sand, snow, and mud. On the other hand, a mountain bike has smaller tires, giving it more speed and agility when biking on various terrains. Of course, mountain bikes are also good for riding in many types of terrains, but fat bikes are better for mud, snow, and sand.

Should you get a Fat Bike

The main reason to get a fat bike instead of a traditional mountain bike is that they are less expensive than most mountain bikes. Another reason to get a fat bike is that they’re fairly easy to ride in any weather condition, allowing you to enjoy biking all year round. In addition, they’re versatile and can be used for commuting or for going on long off-road rides. Lastly, fat bikes can handle terrain with limited traction better than traditional mountain bikes.

Who would benefit from owning a fat bike?

If you live in an area of the world with a lot of soft ground or commute through these types of terrains regularly, you may benefit from owning a fat bike. Also, owning a fat bike might be a good idea for people who don’t need to ride very far. They are not fast, but they can ride over any obstacles while being more comfortable.

What are the best brands and models of fat bikes that offer great quality bikes at affordable prices?

Mongoose makes the most affordable fat bikes with their Mongoose Dolomite Fat Tire bike. The quality of these bikes is enough for the average rider, and they provide a comfortable ride.

  1. A mountain bike provides a riding experience that is much more fun and enjoyable.
  2. The fat bike is better in soft terrain and snow that don’t require much speed, but the mountain bike can easily handle steeper, rougher terrain.
  3. They are designed for different purposes.
  4. Mountain bikes have higher ground clearance, wider ranges of gears, and are designed to tackle rough terrain.
  5. Fat bikes have huge tires that can easily roll over snow or sand but don’t offer much stability on tougher terrain.
  6. Mountain Bikes are often more durable than fat-tire bikes.
  7. Mountain bikes might have a higher resale value and sell faster than a fat tire bike once you are done with it.

Who would benefit from owning a Mountain Bike?

Mountain bikes are great for people who want to ride on both hard and soft terrain. They have wide ranges of gears, which allows riders to take on any trail. Furthermore, since they have smaller tires, they are much lighter than a fat tire bike, making them easier to ride.

Fat bike tires have more rolling resistance than mountain bike tires, which means they require more effort to maintain the same speed on smooth pavements.

What are the most common tire pressures for fat bike tires?

Most fat bike tires are typically inflated to around 5-10 psi, depending on the rider’s weight and the type of terrain.
