What Are Mountain Bikes with Fat Tires?

Mountain bikes come with different sized tires, and you can choose the size you prefer. In general, electric mountain bikes have 3-inch wide tires.

For an electric mountain bike to be considered a fat tire e-bike, it needs to have tires between 4 and 5 inches wide. This size is much wider than the standard tires on an e-bike or an electric mountain bike.

The width of the tires is not the only thing to be taken into consideration. While size and width are very important and can play a significant role in how well you can ride your bike, you also have to consider whether the tires are studded or not, tubed or tubeless, high-quality or low-quality, and so on.

A fat tire e-bike can be ridden comfortably on almost any kind of surface. This can greatly improve the riding experience, especially when mountain biking and riding in different off-road conditions. The tire’s air pressure can be adjusted to suit most kinds of surfaces.

An e-bike with tires wider than 4 inches are usually considered fat tires. However, there are more and more options available as time goes on, so 4 to 5-inch wide tires are more often referred to as “super fat” tires. Super fat tire e-bikes are great for riding on loose rocky ground and wet surfaces.

Another range of width that might be considered as fat tires is 2.8 to 3.8 inches. While this width isn’t too fat as compared to the super-fat tires, it is still quite wide.

The standard width of electric mountain bike tires is 2.6 inches or less. So, even though 2.8 inches isn’t that wide, it is wider than the standard and, therefore, can be considered a fat tire.

An e-bike with tires wider than 4 inches will likely have more traction than one with tires thinner than 4 inches. However, even 3-inch wide tires will offer you more surface area than the standard 2.6-inch wide tires.

The air pressure in your fat tires can also make a massive difference to your riding experience. Generally speaking, the most common air pressure used in fat tires is between 10 and 20 PSI.

Although the best way to determine the correct air pressure for yourself would be through trial and error, there are some guidelines you can follow to get started.

For example, if you’re riding a fat tire e-bike on a road or pavement, you might want to stick to a PSI between 10 and 20. A PSI between 5 and 8 is a good choice for snow and mud, and for sand or loose dirt, a PSI between 10 and 15 is ideal.

The Advantages of a Fat Tire E-Bike

Fat tire e-bikes would not be so popular in the mountain bike category if they did not offer a number of solid advantages compared to regular tire e-bikes. Let’s consider some of the advantages of a fat tire e-bike:

  • The higher surface area on the fat tires means better traction in different conditions. Fat tires offer better traction in snow and mud, on loose, rocky, or sandy terrain, and on uneven surfaces.
  • A more comfortable ride over rough and uneven terrain that results in less jarring and more comfort on your rear-end during longer and trickier rides. 
  • Increased safety due to better balance from the wider fat tires. While riding a fat tire e-bike, you are less likely to fall or lose balance. Fat tires also offer greater stability due to more surface area contact on the ground.
  • Fat tires offer the advantage of riding through deep mud, sand, or snow but still remaining at the surface and not sinking into the ground.
  • Fat tires last longer due to their extra width and thickness, preventing them from becoming damaged on rough and varied terrain.
  • And lastly, fat tires are not just restricted to off-road riding or mountain biking. They can be great to use on roads and pavements as well. In a way, fat tires allow you to convert your electric mountain bike into a hybrid electric bike that can be used on pavements as well as off-road conditions.

The Disadvantages of a Fat Tire E-Bike

Although there are many great advantages that may sway you into choosing a fat tire e-bike, you shouldn’t decide without looking at the disadvantages first. There are a few disadvantages to consider when it comes to fat tire e-bikes:

  • A significant disadvantage to consider when it comes to mountain bikes with fat tires is the added weight. Fit tire e-bikes can weigh anywhere between 60 to 80 lbs. compared to regular e-bikes that weigh between 40 to 60 lbs. The additional weight is due to the larger tires and rims.
  • Wider tires do not always fit into e-bike parking spots or car bike racks. It can also be harder to lift the bikes into your car or onto a lift or rack.
  • The added weight of the fat tires can lead to more resistance when riding uphill. This can put additional strain on your body and the e-bike’s battery.
  • Wider tires can be flashier and look more expensive, meaning that your electric mountain bike might be more likely to be stolen.
