Fatbike tires are extra-wide tires at least 4 inches (about 10 centimeters) wide. By comparison, a regular city bike has tires about 1.5 inches wide. That width provides a larger contact surface with the road, which directly affects grip, stability and ride comfort.

Originally, fatbike tires were developed for cycling on sand, snow and mud. The wide tires sink less into soft surfaces and offer better traction. Since then, the benefits have become apparent in urban environments as well. A cargo bike with fatbike tires combines the best of both worlds: the practical cargo space of a cargo bike with the stability of a fatbike.

The STOER CargoX is the first electric cargo bike with real fatbike tires. With 20×4 inch tires at the back and 16×4 inch tires at the front, this cargo bike offers a unique riding experience. Want to know more about this model? Check out the STOER CargoX product page.

Why should you choose a cargo bike with fat tires instead of a traditional model? There are several reasons worth considering.

Never get stuck in streetcar rails again

You know that moment? You bike through town, have to swerve for a van, and before you know it, your wheel is stuck in a streetcar rail. With narrow tires, this is almost inevitable. The groove of a streetcar rail is wide enough to catch a standard bicycle tire, but too narrow to get out again. The result: a crash.

Research by Fietsersbond shows that streetcar rails are a major cause of bicycle accidents in cities such as Amsterdam, Rotterdam and The Hague. There are hundreds of kilometers of streetcar tracks in these three cities alone. Fatbike tires on cargo bikes solve this problem. The tires are simply too wide to fall into the groove. You ride right over them without risk.

For parents with children in the cargo box, this is a serious safety concern. A fall with a full cargo bike can have serious consequences. With thick tires, you eliminate this risk.

More grip on any surface

The larger contact surface of fatbike tires provides better grip. You notice this on dry asphalt, but especially on wet streets, cobblestones and loose tiles. Whereas a cargo bike with narrow tires can slip in a turn, a model with wide tires remains stable.

The grip comes not only from the width, but also from the lower tire pressure. Fatbike tires run at 1 to 2 bar, while regular bike tires often require 3 to 4 bar. Because of this lower pressure, the tire adapts better to the road surface. Small bumps are absorbed rather than transmitted to your handlebars.

More stability at full load

You rarely transport a cargo bike empty. With children, groceries or work materials in the cargo box, the weight can add up quickly. The heavier the load, the more important stability becomes. Fatbike tires on cargo bikes offer that stability because of the wider support surface.

Compare it to a car: an off-road vehicle with wide tires feels more stable than a city car with narrow tires. The same principle applies to cargo bikes. The STOER CargoX can carry up to 150 kg. With thick tires, the cargo bike remains predictable and safe even at maximum load.

Cycling more comfortably over vowels

Dutch cities are full of cobblestones, cobblestones and poorly maintained bike paths. With narrow, hard-inflated tires, you feel every unevenness. This is uncomfortable not only for you, but also for the children in the box.

Fatbike tires act as natural suspension. The soft tires absorb shocks and vibrations before they reach your body. Combined with the CargoX's EPP body and front wheel suspension, you get a smooth ride, even over the worst streets. Your kids will hardly notice you're riding over cobblestones.

How do fatbike tires compare to standard cargo bike tires? Here's an overview of the main differences.

The table shows that fatbike tires score better in most areas. The only drawback is slightly higher rolling resistance, but with electric assistance you won't notice much of that.

The STOER CargoX is the first electric cargo bike truly designed around fatbike tires. Where other manufacturers offer fat tires as an option, STOER Bikes has tailored the entire design to the characteristics of wide tires.

Why the CargoX is different

The CargoX's frame is specifically designed for the forces generated by fatbike tires. The wider wheel arches, reinforced frame and modified geometry ensure that the cargo bike performs optimally with fat tires. It is not a compromise, but a well thought-out design.

The Bafang H720 motor with 92 Nm of torque is powerful enough to compensate for the slightly higher rolling resistance of the wide tires. You won't notice any difference in effort compared to a cargo bike with narrow tires. The 960Wh battery gives you 60 to 100 km range, depending on load and riding style.

"We saw that parents and business owners needed a cargo bike that is truly stable in all conditions," says co-founder Thomas of STOER Bikes. "The combination of thick tires with our frame and motor system ensures that every ride is smooth and safe, whether you're transporting kids or heavy loads."

German Design Award 2025

The CargoX won the German Design Award 2025 in the category Excellent Product Design - Bicycles and E-Bikes. This international recognition confirms that the fatbakfiets is not just a gimmick, but a well thought-out piece of Dutch design. The jury praised the combination of functionality, safety and appearance.

Safety is the most important argument for many parents when choosing a cargo bike. Fatbike tires on cargo bikes contribute to a safer riding experience in several ways.

Shorter braking distance in the wet

Because of the larger contact surface, fatbike tires have more grip when braking. This difference is especially noticeable on wet roads. Whereas narrow tires can slip during emergency braking, fat tires stay in contact with the road.

The CargoX is equipped with Tektro hydraulic disc brakes that work perfectly with the wide tires. The combination ensures short, predictable braking distances in all weather conditions. The integrated brake light warns traffic behind you when you are braking.

Better visibility in traffic

A cargo bike with fatbike tires stands out. The wide tires and tough appearance attract the attention of other road users. That extra visibility can make all the difference in heavy city traffic.

The CargoX also has turn signals integrated into the body, just like a car. Combined with the LED daytime running lights, you are always highly visible, even on cloudy days.

Stable in evasive maneuvers

Suppose you suddenly have to swerve from an opening car door or a pedestrian crossing the road. With narrow tires, such a maneuver can lead to loss of control, especially with a full tank. Fatbike tires give you the grip and stability to swerve safely without swaying.

In addition to safety, fatbike tires on cargo bikes offer practical benefits that you notice on a daily basis.

Less frequent flat tires

Fatbike tires are thicker and sturdier than standard bicycle tires. The thick wall better protects against sharp objects such as glass or nails. Combine that with the lower tire pressure and you're less likely to puncture. A flat tire on the road with kids in the tub is the last thing you want.

Less frequent pumping

Because of the lower usage pressure of fatbike tires, the tire is less likely to lose air. Whereas you have to check standard tires every two weeks, fat tires hold their pressure much longer. That saves time and hassle.

Higher carrying capacity

Fatbike tires have a higher load capacity than narrow tires. This is relevant for cargo bikes, which are often heavily loaded. The CargoX's tires are calculated for the maximum payload of 150 kg plus the weight of the rider. No need to worry about overloading.

To be fair, fatbike tires also have disadvantages. It's good to know those before making your choice.

Slightly higher rolling resistance

Because of the larger contact area, fatbike tires have a slightly higher rolling resistance than narrow tires. Without electric assistance, you would notice this as heavier pedaling. With the CargoX's powerful motor (92 Nm of torque), this difference is negligible. You pedal as lightly as on any other electric cargo bike.

Wider profile

A cargo bike with fatbike tires is wider than a model with standard tires. In very narrow alleys or bike racks this can be a disadvantage. The CargoX is 70 cm wide, which is comparable to other cargo bikes. In practice, you notice little difference.

Striking appearance

Not everyone likes the tough look of fatbike tires. It's a matter of taste. Do you like a traditional cargo bike better? Then a model with fat tires may not be for you. But more and more people actually appreciate the striking design.

A cargo bike with thick tires is not the best choice for everyone. Below are the target groups that benefit the most.

Families in cities with streetcar lines

Do you live in Amsterdam, Rotterdam, The Hague or Utrecht? Then the streetcar rails argument alone is enough to choose fatbike tires on bakfiets. Your children's safety is worth it.

Parents who drive over cobblestones a lot

Does your daily route have a lot of cobblestone streets or poorly maintained bike paths? Then thick tires make for a more comfortable ride for you and your kids. Less jarring also means less howling from the box.

Entrepreneurs with heavy loads

Do you use the cargo bike on business for delivery or transportation? Then stability when fully loaded is important. Fatbike tires give you the grip and control you need, even with 150 kg in the cargo box.

Cyclists who value safety

Are you someone who prefers not to take risks? Then thick tires offer extra security. The better grip, stability and elimination of streetcar rail risk make every ride safer.

Fatbike tires require little maintenance, but there are a few things to watch out for.

Checking tire pressure

Check tire pressure monthly. For fatbike tires, the ideal pressure is between 1 and 2 bar, depending on your weight and load. Tires that are too soft wear out faster and increase rolling resistance. Tires that are too hard lose their comfort advantage.

Inspect profile

Check the tread regularly for wear and damage. Fatbike tires last a long time, but visible wear requires replacement. STOER dealers are happy to help you with tire changes and other maintenance.

Keeping clean

Regularly remove dirt and stones from the tread. This extends the service life and prevents sharp objects from working their way into the rubber.

Are fatbike tires suitable for daily use in the city?

Yes, fatbike tires are excellent for daily urban use. They offer extra grip, stability and comfort on cobblestones, streetcar rails and wet roads. With electric assistance, you won't notice the slightly higher rolling resistance.

Will fatbike tires still allow me to go through narrow alleys?

The CargoX is 70 cm wide, similar to other cargo bikes. In most situations you won't notice any difference. Only in very narrow thoroughfares can the width be a concern.

How often should I inflate fatbike tires?

Fatbike tires hold their pressure longer than standard tires. Check pressure monthly and inflate if necessary. The ideal pressure is between 1 and 2 bar.

Do fatbike tires break down quickly?

No, fatbike tires are actually sturdier than standard tires. The thick wall protects well against sharp objects. With normal use, they will last for years.

Is a cargo bike with thick tires heavier to ride?

Without a motor, you would notice the slightly higher rolling resistance. With the CargoX's powerful Bafang motor (92 Nm of torque), you won't notice any difference. The electric support compensates completely.

Why don't all cargo bikes have fatbike tires?

Fatbike tires require a modified frame design and more powerful engine. Not all manufacturers invest in this. The STOER CargoX is specially designed around fat tires, which makes all the difference in ride quality.
