1.Choose Suitable Fat Bike Hub Width
Fat bike wheels have gone through various iterations of hub width.To begin with, they were offset 135 mm width hubs, your old mountain bike standard. As the popularity of fat bikes started to grow, manufacturers began to produce dedicated fat bike hubs and fat bike frames to support these new hub standards.
The biggest game-changer was moving to thru-axles. Thru-axles better support the weight of huge wheels. It was possible to break quick-release axles that held fat bike wheels on before. The move to thru-axles has found that most fat bikes now use a 15mm x 150 mm front axle. There are a few notable exceptions, such as the Surly Pugsley that use an offset 135 mm front wheel. That is why you need to double-check what you have.
At the back end of a fat bike, there have been a few standards before we settled on one a majority favorite. The majority of fat bikes will now use a 190 mm or 197mm by 12 mm thru-axle. Some will come with a 190 mm quick-release.
There is also a standard that fits between plus bikes and 5” tired fat bikes. That is the 10 or 12 mm axle with either a 170 mm or 177 mm width. This option will generally be found on bikes with less than 5” tire clearance. Again, bikes such as the Surly Pugsley use a completely different option of 142 mm by 12mm. That is so you can fit a Rohloff hub.

3.Fat Bike Wheel Rims Material
Number of fat bike wheelsets spokes
Spokes are an important part of wheelsets, which affect the performance of the entire wheelset.
Generally speaking, lighter mountain wheels usually run 24-28 spokes per wheel, stronger off-road or all-mountain wheels may use 28 spokes, and the strongest wheel systems usually use 32 spokes. These numbers are not set in stone, but generally speaking, more spokes means stronger.
So when you buy fat bike wheelsets, you need to know the number of spokes, which is the number of holes. The more spokes, the stronger the bike wheelsets.
The spokes also determine the feel of the wheel. Heavier spokes make the wheel harder but stronger, while lighter spokes do the opposite. For example, Sapim CX-Ray is a good spoke product due to its strength-to-weight ratio and is widely used in our wheel construction. Sapim Force spokes are stronger and stronger for use in MTB and gravity-oriented wheel construction.
What are fat bike wheels for?
Fat bike wheels are very suitable for snow riding environments, which are intended for riding on rougher surfaces.Whether it’s the sand or rocky landscapes, the fat bike wheels can run well.
Are fat bikes good for heavy riders?
Because of the wider tire and good carrying capacity of fat bike, which is very suitable for overweight cyclists.Usually fat bike wheels are up to 90mm wide, which can transmit most of the pressure to avoid discomfort.
Now you can avoid the pitfalls of buying the wrong size hub for your fat bike, and you also have a quick and easy guide to make sure you get the correct rim width for your tires. The only thing to do now is to work out if you can afford aluminum or carbon fiber rims. Going carbon will be lighter, easier to set up tubeless, and brings you a better ride-feel out on the trail, so I’d suggest going carbon fiber.
