How to Choose a Fat Tire Mountain Bike – 3 Things to Know

the fat tire mountain bike is standing on the grass

To select the perfect fat bike, you have to consider quite a few features. Three, in particular, are most important when looking at top-rated fat tire mountain bikes:


As you look at fat tire mountain bike reviews, you’ll find that these bikes are different from full suspension MTB. Most fat bikes are a hardtail MTB with a rigid fork. If you ride on uneven or rocky surfaces, you may want a bike with full-carbon suspension to help you control it better. However, a rigid fork may be better for riding in cold temperatures.


You should consider the fit of your bike, whether it is full-suspension or hardtail. Having higher standover is not a bad thing, but you may want to downsize if your standover is over three inches.

Wheel size

There are a few 27.5 fat tire mountain bike models on the market and even some 29er fat tire mountain bike options, but most fat tire bikes use 26-inch tires. Bigger wheels can help you go faster and roll over obstacles. If you are looking to ride on mostly trails, you can also look into dirt trail mountain bikes.

What are the Advantages of Having Fat Tires?

Fat bikes have many advantages:

  • They are fun to ride. Regardless of your age, riding a fat bike will put a smile on your face. You can go fast or slow and enjoy the thrill of being on a bike again. Some riders explain it as being similar to riding a monster truck.
  • They are comfortable. The large, low-pressure tires absorb shock so you can have a comfortable ride. Unlike athletic bikes, you can sit back and cruise with minimum stress on your arms and lower back. You can also adjust the tire pressure based on the riding conditions.
  • You can ride on most terrains. As we’ve expressed many times, the joy of fat bikes comes from their versatility. You can ride the bike all seasons for any occasion. You may even enjoy fat bike races during the summer. For more racing bikes, take a look at Enduro racing mountain bikes.
  • You’ll want to ride your bike. People who own fat bikes tend to ride more often than most other bike-owners. They enjoy the ride, the workout, and the attention they get from other people who are curious about fat bikes.

What Types of Terrains Can a Fat Tire MTB Handle?

The best fat tire mountain bikes allow you to ride on terrains you couldn’t tackle on a standard bike. These bikes can handle:

  • Snow
  • Sand
  • Rocks
  • Logs
  • Mud
  • Dirt

Fat tires help mitigate impact issues that would stop other smaller bikes. They can travel across loose sand because the large surface area of the wider tires disperses your weight so that you don’t sink in. However, you may still have some trouble with light, fluffy snow.

If you are a beginner biker, you might enjoy the slow pace of a fat bike. They are easy to handle, and you can trust them to take you over any tricky roads. If you’re not sure you’ll like it, there are also plenty of cheap fat tire mountain bikes on the market to test the trail with.

Some riders choose to add motors to their bikes to expand their limits and travel faster. You can find fat tire electric bikes if you want a bike with a motor.
