FREQUENTLY ASKED QUESTIONS

NÜOBELL is an adjustable dumbbell system designed to replace multiple pairs of traditional dumbbells with one compact set. Simply twist the handle to select your desired weight, lift the dumbbell from its cradle and start training.

Both NÜOBELL and NÜOBELL S use our patented adjustable dumbbell technology and are designed in Sweden.

Yes. Both NÜOBELL and NÜOBELL S are available in kg and lb versions, depending on the market.

NÜOBELL

• 2–20 kg (220) / 5–50 lb (550)
• 2–32 kg (232) / 5–80 lb (580)

NÜOBELL S

• 2–24 kg (S 224) / 5–60 lb (S 560)
• 2–40 kg (S 240) / 5–100 lb (S 5100)

Please note: The lb versions are exclusively available in the US market, while the kg versions are available in Europe.

Both NÜOBELL and NÜOBELL S use the same space-saving adjustable dumbbell concept, but differ in construction, weight range and design.

NÜOBELL has a quiet and smooth construction using plastic and nylon components alongside powder-coated cast-iron weight plates and anodized aluminum. It features two rotating half-weight plates and is available up to 32 kg / 80 lb per dumbbell.

NÜOBELL S is built on a reinforced platform with stainless-steel V-connectors, a new aluminum handle and four rotating half-weight plates. Its reinforced construction supports a higher maximum weight of 40 kg / 100 lb per dumbbell.

NÜOBELL is designed for a quiet and smooth training experience, while NÜOBELL S has a sturdier, reinforced construction designed to handle heavier workouts.

Both NÜOBELL and NÜOBELL S are designed for home training, combining a compact footprint with fast and easy weight adjustment. Which model is right for you comes down to your training needs and personal preference.

NÜOBELL offers a quiet, smooth and well-balanced training experience, with weight options up to 32 kg / 80 lb.

NÜOBELL S has a sturdier, reinforced construction designed to handle heavier workouts, with weight options up to 40 kg / 100 lb.

You don't need to start with the highest weight range. Both models offer a lighter option that can be expanded as your strength and training needs progress. NÜOBELL 220 can be expanded to 232, and NÜOBELL S 224 to S 240. In the US, the corresponding lb models can be expanded from 550 to 580 and from S 560 to S 5100.

Ultimately, your choice can also come down to personal preference: whether you prefer the quieter, smoother construction of NÜOBELL or the sturdier construction and higher weight capacity of NÜOBELL S.

NÜOBELL and NÜOBELL S allow you to move through the weight range in small, consistent increments.

The kg models adjust in 2 kg increments, while the lb models adjust in 5 lb increments. Simply twist the handle to your desired weight and lift the dumbbell from its cradle.

Our weight plates are powder-coated cast iron. Our handles and cradles are made of anodized aluminum, while the plastic components are made from ABS and nylon polyamide to keep the dumbbells quiet, smooth and low-maintenance.

NÜOBELL S also features stainless-steel connectors, introduced in response to customer feedback and to support its heavier weight range. This more robust construction means NÜOBELL S may produce slightly more sound during use compared to the original NÜOBELL.

No. NÜOBELL and NÜOBELL S are precision adjustable dumbbells and should not be dropped or slammed.

Unlike a fixed dumbbell, an adjustable dumbbell contains an internal selection mechanism and multiple connected components. Always place your NÜOBELLs down in a controlled manner after your set.

Dropping or slamming damage is not covered by the warranty.

Yes. Space efficiency is one of the main advantages of NÜOBELL.

Depending on the model, one pair replaces multiple pairs of traditional fixed dumbbells while occupying approximately the footprint of a single dumbbell pair in its cradles. For example, NÜOBELL 232 replaces 16 pairs, while NÜOBELL S 224 replaces 12 pairs.

NÜOBELL and NÜOBELL S are available in a selection of colors. Availability varies by model, you can find all available colors here.

Place the dumbbell fully in its cradle and twist the handle until your desired weight is displayed. Lift the dumbbell straight out of the cradle and only the selected weight plates will come with it.

The patented twist-handle system allows you to change weight in one motion, making it particularly convenient for supersets and drop sets.

If your NÜOBELL handle isn't adjusting properly or the weight selection mechanism seems stuck, there are a few things you can check before contacting Customer Care.

1. Check the cradle and weight plates. Make sure the dumbbell is correctly positioned in its cradle and that all weight plates are properly aligned.
2. Inspect the inner support. Check that the pin on the inner support is free from damage.
3. Test the handle. Try placing the non-working handle in the cradle of your working dumbbell to see if the issue persists.
4. Check for any gaps. If there is a noticeable gap between the handle and the weight indicator section, stop using the dumbbell immediately. This may indicate an issue with the internal mechanism.

Never force the handle if it isn't adjusting properly.

If the issue persists, please contact our Customer Care team with your order number and a short video showing the problem so we can help you find the right solution.

If you're replacing your NÜOBELL handle and the weight plates remain attached to the old handle, please follow our step-by-step instruction video for safely removing the plates.

Watch the instruction video

Do not force the plates off or attempt to disassemble the mechanism without following the instructions. Please note that you have to use a lot more force than shown in the video.

If you need further assistance, our Customer Care team is happy to help.

NÜOBELL is designed to be low-maintenance, and the handle mechanism arrives pre-lubricated from the factory.

Keep the dumbbells and cradles clean and dry, avoid dropping or slamming them and always follow the care instructions in your user manual.

If something does not operate as expected, contact NÜO or your authorized reseller rather than attempting to modify the mechanism yourself.

A small amount of movement and spacing between the weight plates is completely normal.

Due to the adjustable design, the plates need a certain amount of space to allow the dumbbell to pick up and release individual weight plates when changing weights.

However, if you notice an unusually large gap, excessive movement or anything that seems out of the ordinary, stop using the dumbbell and contact our Customer Care team with photos or a short video so we can assist you.

User manuals are available for NÜOBELL, NÜOBELL S, Floor Stands and Expansion Kits on our User Manuals page.

We also have step-by-step instruction videos on our YouTube channel, covering assembly, handle replacement and how to remove weight plates that have become stuck on the handle.

Always read and follow the user manual before assembling or using your NÜOBELL. Correct assembly is essential to ensure safe and proper operation.

The NÜOBELL S Pylon Floor Stand is compatible with all current NÜOBELL models, including NÜOBELL 220 / 550, 232 / 580, S 224 / 560 and S 240 / 100.

The original NÜOBELL Floor Stand can also be used with NÜOBELL S together with the NÜOBELL S Adapter Kit.

No. Every NÜOBELL comes with cradles that allow you to store the dumbbells and change weights.

A floor stand is optional and raises the dumbbells from floor level, making storage and weight changes more convenient.

Yes. Genuine replacement parts are available for both NÜOBELL and NÜOBELL S, including handles, plates and other selected components.

Always use genuine NÜO replacement parts designed for your specific model. You can find all available replacement parts here.

Replacement instructions depend on the component and model.

Follow the relevant NÜO instruction video or user manual. If you're unsure which part you need or how to replace it, contact our Customer Care team before attempting the repair.
