If this is the first time that you’re riding a big bike, you may have noticed that some things are harder now than when you may have ridden a small bike. Handling this big fellow is a bit harder. The weight is more of a concern whether you’re riding your big machine or just pushing it along. Sometimes you wonder if riding the big fellow up a hill is different than when you ride a small bike up that same hill.

Here’s the popular notion: Fat bikes can be more difficult when it comes to climbing elevations, riding through tough locations, or picking up speed when it is necessary for it to do so.

So, a rider may wonder if smaller bike rims will make more sense under a fat bike. The idea is to shed some weight wherever possible. However, one thing stands out. The bike rims and tires need to be strong, sturdy enough to hold the weight of a fat bike. They must be strong enough to withstand any difficulties they meet, no matter where the bike goes.

What about the big holes that come with the fat rims of these bikes? Are they necessary? Could they make any difference? What if they are not there at all? Or the holes were made to be smaller considerably than they are at the moment?

What really makes sense?

In this write-up, we will consider the science behind fat bike rims with big holes. What are the disadvantages of having those holed in the rims?

The Science Behind Fat Bike Rims & Big Holes

You may sometimes fret over the big holes you see in your fat bike rims. Maybe they make the bike itself cost more. Could there be any other advantages attached to having the holes in place?

Experts have solved the riddle. They claim that the big holes we often see in fat bike rims are there to reduce the weight of the wheels in the most efficient way possible. This explanation seems very reasonable because we all know that just by looking at the rims of fat bikes, we know they are heavy. Therefore, it makes sense for both professional riders and casual riders to look out for fat bike rims with big holes. The difference may not be much, just a few hundred grams of weight but it does make some difference.

The width of the rims is big enough to balance things up with the holes. The holes are not able to reduce the strength of the rim in any way. There have been many ideas along these lines for many years, but this trick worked out as the best out of all.

The scientific finding is clear: there are no disadvantages to having those holes there at all. However, they must be done correctly. In this way, it becomes the job of manufacturers to make the holes on specific bike models at first. The idea’s success has led to more bike models having the holes cut on their rims.
