Fat bike riders are always keen to tell you why you should ditch our mountain bike and go for a bike with wider tires. Mountain bike die hards will tell you why fat bikes are simply not as good as mountain bikes and you should steer clear of them. This begs the question, which is better a mountain bike or fat bike? In this guide, I look at the pros and cons of each and provide some guidance on when you should choose one over the other.

Key Takeaways

Fat bikes are better for all year round riding due to their ability to cover multiple terrains with ease. If you mainly riding offroad in warmer weather then you should choose a mountain bike as they are lighter and easier to ride in these conditions.

Which Is Better A Mountain Bike Or Fat Bike

What Is a Mountain Bike?

A mountain bike, also referred to as an all-terrain bicycle, is a type of bicycle designed for off-road cycling. This type of bike is typically built with strength and durability in mind so that it can handle the rough terrain found on trails and other off-road settings. Mountain bikes usually have wider tires with aggressive tread patterns that provide additional traction and control while riding on dirt or gravel paths. They also typically feature front suspension forks that help absorb impacts from bumps in the road.

Mountain bikes come in a variety of different styles, each one tailored to certain types of terrain and riding preferences. Cross-country mountain biking focuses on lightweight designs for long distance rides over flat terrain, while downhill mountain biking emphasizes strength and stability for navigating downhill slopes at high speeds.

What Is a Fat Bike?

A Fat Bike is a type of mountain bike that has been designed with extra-wide tires to tackle difficult terrain. This type of bike is also referred to as a “fatty” or “snow bike”, and it has found its way into the hearts of many bikers due to its ability to conquer trails on both dry and wet terrain, as well as snow and sand. 

The defining feature of a Fat Bike is its larger than average tires, which are typically 3.7 inches (9 cm) wide or wider. This wide tire design allows for better traction across various terrains, such as mud, snow, and sand. The increased contact patch also helps reduce rolling resistance and increase stability when riding on rough ground or off-road trails.

Pros of Fat Bikes

Fat Bike Are Great on Snow, Ice and Other Loose Surfaces

One of the main advantages of fat tire bikes is their ability to handle snow, ice and other loose surfaces with ease. 

The larger tires on fat bikes help to provide better stability while riding over snow, ice or other loose surfaces that would normally cause traditional mountain bikes to slip and slide around. The wide design also helps increase traction when negotiating hills or sharp turns, allowing riders to enjoy greater control over the bike’s movements.

Fat Bikes Are More Comfortable To Ride

Another advantage of fat tire bikes is that they provide a smoother ride on many different types of terrain. The extra-large tires not only provide added cushioning for increased comfort, but also more stability and traction which can make off-roading safer. The wide tires on a fat bike absorb shocks better than traditional road bikes and minimize the risk of bumps causing discomfort on rides.

Fat Bikes Have Better Traction And Grip

One of the biggest advantages of fat bikes is that they have superior traction compared to traditional mountain bikes. This added traction makes fat biking easier and more enjoyable for cyclists who want to tackle challenging terrain or wade through wetter climates. Fat bike tires provide maximum control while navigating rocky terrain and offer enhanced stability while riding over snowy surfaces or mud puddles. The thick treads also help absorb shock better than thinner bike tyres, reducing rider fatigue and making it easier to maintain speed uphill or on bumps in the road.

Cons of Fat Bikes

Fat Bike Can Be Expensive To Maintain

As fat bikes are designed for extreme-weather conditions, they require specialized components and high-performance parts that can add up quickly. The thick tires must be replaced more often than regular mountain bike tires due to their added weight and friction on rougher surfaces. They also need frequent lubrication of hubs and bearings in order to keep them running smoothly. Furthermore, additional parts such as brake pads and chains tend to need replacing more often than other types of bikes due to the increased pressure put on them by heavier riders or extended use in wetter climates.

Fat Bikes Weigh a Lot

A fat bike is heavier than other types of bicycles, typically weighing between 18-30 lbs compared to 10-20 lbs for other mountain bikes. This extra weight makes it harder for the rider to maneuver and accelerate with any speed. On steep terrain, fat bike riders may struggle to get up hills due to the added heft of the bike. 

The additional weight also makes it more difficult to store and transport a fat bike. Bicycle racks designed for traditional bikes are not always equipped to handle a much bigger and heavier fat tire bicycle without requiring some modifications or specialized attachments. The sheer size and mass of a fat bike can limit its usefulness as an everyday commuter vehicle, making it better suited for light off-road use rather than regular city commuting due to its cumbersome nature.

Fat Bikes Are Slower Than Other Bikes

Fat bikes are generally slower than other bikes, primarily because fat tires require more energy to push and turn compared to normal bike tires. This means that when it comes to average speed over flat terrain or up hills, a fat bike will usually lag behind a normal mountain bike or road bike in terms of speed. In addition, the sheer weight and size of a fat bike can add extra resistance while cycling, making it even harder to reach higher speeds quickly. 

Fortunately, most riders who use fat bikes don’t mind their slower speed as they tend to enjoy the comfort and stability that these vehicles offer on tricky terrains.

Pros of Mountain Bikes

Mountain Bikes Are Easier To Maintain

While fat bikes offer an off-road experience like no other, one major advantage mountain bikes still have over them is that they are much easier to maintain. 

The main difference between mountain and fat bike maintenance lies in their tires. Fat bike tires are much thicker than those seen on traditional mountain bikes, meaning that more air pressure is needed for the same amount of rolling resistance. This extra air pressure can cause issues with tire wear and tear over time as more force is exerted on the inner tube walls when riding.

The components on a mountain bike are also easier to source, meaning that if something does go wrong it is generally easier to find the replacement parts you need.

More Affordable 

The wide availability of mountain bikes makes them more affordable than fat bikes. Many retailers and manufacturers offer various models at different prices, so riders can find something that fits their budget without sacrificing quality. Additionally, there are plenty of used markets available online where one can get a good deal on a used bike or even purchase parts or accessories at discounted rates. 

They Weigh Less

Another advantage of mountain bikes is that they weigh less than fat bikes. This makes them easier to transport and store, as well as being less fatiguing when riding longer distances. Fat bikes are a great option for those who need extra traction or stability on difficult terrain, but their heavier frame can make them more cumbersome to ride on flat surfaces or for long periods of time.

In comparison, mountain bikes typically weigh anywhere from 10-20 pounds depending on the model and components chosen. This makes them significantly lighter than fat bike frames which usually range between 18-30 pounds. The lightweight design allows mountain bikers to move quickly over various types of terrain with ease while remaining comfortable during the ride.

Cons of Mountain Bikes

Mountain Bikes Struggle On Snow And Ice

Because mountain bikes are designed for off-road conditions like dirt, gravel, sand, and mud, its tires offer limited traction when the weather turns cold. While wider tires can provide some stability on icy surfaces, their grip will be significantly reduced compared to winter specific options such as studded tires or fat bike wheels. As a result, riding a mountain bike on snow or ice can be extremely dangerous due to the lack of grip it provides.

Mountain Bikes Provide A Rougher Ride

Fat bikes are specially designed for off-road use and feature oversized tires that provide more cushion and stability on uneven surfaces. In comparison, standard mountain bike tires are narrower and harder making them less forgiving on rough terrain. Additionally, since fat bike tires have wider contact patches they offer more grip when going over rocks or through mud. 

Ultimately, both types of bicycles can be used for off-roading; however those looking for a smoother ride should consider investing in a fat bike instead of a traditional mountain bike.

Mountain Bike Wheels Get Damaged Easier

Mountain bike riders should be aware that their wheels are more vulnerable to damage than other types of bikes, such as fat bikes. The thinner and lighter tires on a mountain bike make it easier for sticks and rocks to puncture them when riding on rough terrain. Because of this, mountain bikers must be especially vigilant when riding off-road in order to avoid potential wheel problems. 

In addition, the rims of mountain bikes are usually narrower than those found on fat or cruiser bicycles which also makes them more susceptible to impact damage from large bumps or drops. Therefore it’s important for a mountain biker to take extra care when going over obstacles that could cause harm to their wheels.

When Is a Fat Bike Better than A Mountain Bike?

A fat bike is essentially a mountain bike with over-sized tires that provide riders with better traction on uneven surfaces such as snow or sand. The additional weight of these bikes helps to keep them steady on loose ground and provides more stability than traditional mountain bikes. The wide tires also make for a smoother ride in general compared to other types of bicycles because they absorb more shock from bumps or rocks in the road. For individuals looking for an outdoor adventure over rugged terrain, this makes fat bikes the optimal choice for their needs.

If you are looking for a bike that you can use all year round that can be used on multiple terrains, then a fat bike is a good choice.

When Is a Mountain Bike Better than A Fat Bike?

Mountain biking requires agility, so if you’re looking for a speedy ride that can easily handle tight turns and quick changes in elevation, a mountain bike is the way to go. Mountain bikes are also lighter than their fat counterparts, making them easier to carry up steep inclines or on long rides. However, with its extra-wide tires and low pressure suspension system, a fat bike can be invaluable when tackling difficult terrain such as muddy trails or deep snow. The added traction makes it much easier to keep your balance over uneven ground an advantage that could save you from spillage in difficult conditions.

If you will be riding mainly in the warmer months and want a bike that is fast and easy to manouvre, a mountain bike would be the best choice.


So there you go, I hope you enjoyed this guide. Fat bikes and moutain bikes are designed for similar purposes, but have their pros and cons in different situations. It is important that you think about the type of riding you will be doing before deciding which will be better for you.
