Ultimate S1+ Black

"Very nice and fast service. Contacted via email and next day response and solution offered. Problem solved, totally super! Anyway totally happy with me fatbike from tough!"

"I've had my bike from StoerBikes for a while now and I'm still super happy with it! The service is really top-notch - I can always go to them, and they always help me quickly and well. That really makes me feel good."

"The high-quality components and neatly finished buddyseat add to the quality and appearance of the bike. A unique feature of the Urban X is the motor interruption when braking."

"Finally a fatbike you can ride without having your knees next to your ears."

"So happy with my cargo bike from STOER! 🚲✨ It really cycles SO wonderfully and smoothly - even with multiple kids in the cargo box, it feels super stable and light. What I also find a mega plus: the thick tires. That makes cycling not only comfortable, but also safe and sturdy, especially in the city and on different surfaces. You can just tell that this is a quality bike that has been well thought out. I use it every day and would choose it again in a heartbeat. Highly recommended 🤍 Love, Korall".

"The bike is perfect for people with long legs. Sitting comfort is perfect for long distances."

"The image of fatbikes doesn't stop the entrepreneurs behind the STOER Bikes brand. They focus on the adult cyclist."

Powerful 960Wh battery

The Ultimate S1+ from STOER Bikes is equipped with a removable 960Wh battery. This gives you a range of approximately 60 to 100 km, depending on your riding style, the selected assistance level, and the conditions.

The battery provides enough capacity for both daily rides and longer distances. Thanks to its removable design, you can easily charge the battery indoors. This gives you flexibility and gets you ready for your next ride in no time.

Gates CDX belt drive - low maintenance and quiet

The Ultimate S1+ is equipped with a Gates CDX belt drive instead of a traditional chain. The advantage of a belt drive is that it doesn't need to be lubricated and attracts less dirt. This means it requires less maintenance.

In addition, a belt drive operates smoothly and quietly. The belt is resistant to rust and various weather conditions, ensuring a reliable and durable drive for everyday use.

Immobilizer with 4-digit PIN code

This fatbike is equipped with an immobilizer that works via a 4-digit PIN code. Without the correct code, the bike cannot be turned on.

This provides extra protection against theft. Entering the PIN is quick and easy, giving you a practical way to add an extra layer of protection to your electric bike.

Luxury leather saddle for two

The Ultimate S1+ is equipped with a comfortable leather seat that can accommodate two persons. The wide design and soft finish ensure a comfortable seat even on longer rides.

The saddle provides good support for both rider and passenger while giving the bike a luxurious look. So you ride together comfortably and in style.

Automatic 2-speed motor

The Bafang H720 2-speed motor combines power and efficiency in a single system. Thanks to the automatic two-speed system, the motor automatically shifts between low and high gears, allowing you to accelerate smoothly and continue riding comfortably at various speeds.

The motor provides powerful support in headwinds and on inclines, while its quiet operation ensures a pleasant riding experience. Ideal for daily use in the city as well as for longer rides outside.

Safe braking with Tektro hydraulic disc brakes

This bike is equipped with Tektro Hydraulic disc brakes for powerful and reliable braking performance. Thanks to the hydraulic system, you can brake in a controlled and even manner without having to apply much hand pressure.

Even in the rain or at higher speeds, the brakes provide reliable stopping power. This gives you confidence in city traffic, in unexpected situations, and on longer drives. So you can hit the road with peace of mind.

LED lighting with brake indication

This bike is equipped with bright LED lights, so you're clearly visible in traffic. The taillight has a built-in brake light that turns on as soon as you brake. This way, drivers behind you can clearly see when you're slowing down.

This helps keep you safe, especially in the dark and in heavy traffic. You’ll be clearly visible, and other road users will be better able to react to you.

From design to production

At STOER Bikes, it’s all about design, innovation, and quality. Driven by our passion for bicycles, we—the founders—have developed a bike that is powerful, reliable, and stylish. From the first sketch to the final production, we handle everything in-house to ensure that every detail is just right.

We work with specialists, test our bikes extensively, and make improvements where necessary. This ensures that every bike meets our high standards and is ready for intensive daily use.

What started as an idea has grown into a brand we're proud of. With STOER, we're showing that electric biking can be cool, too.
