Frequently Asked Questions

This video provides information and tips on how to use NÜOBELL safely and correctly. This applies to both NÜOBELL 220 & 232 and NÜOBELL 550 & 580.

Our weight plates are powder coated iron cast. Our handles are made of anodized aluminum along with the cradle. The plastic details are ABS and Nylon polyamide to make the NÜOBELLs quiet, smooth and maintenance free.

The NÜOBELLs are made for training at home. The mechanism is advanced technology, and like most adjustable dumbbells, they are not designed to be dropped continuously.
Many can agree that quietness, design, easy and smooth weight adjustments with low increments are key for residential use; this is a compromise on the extreme durability. Use them normally, with love and care and they will last (almost) forever.

We produce NÜOBELLs in kg and lb and deliver according to our reseller’s local preferences. The weight range conversion from Kg – lb is approximate with a minor deviation:

• 50 lb = 22.7 kg
• 80 Lb = 36 kg

NÜOBELLs is produced in a variety of colors. Our standard is black. However, we do sometimes create custom colors for authorized resellers. Please visit the authorized reseller in your region to find out what colors of NÜOBELL they have available.

Actually it’s not like any other plastic – we use ABS and Nylon polyamide. Nylon is proven to be a harder material than aluminum, is one of the strongest engineering plastics, with high tensile, impact strength, and high abrasion resistance while also having high lubricity. We use Nylon to protect the units and make it quiet and smooth during exercise, and hold the plates together. ABS allows material flexibility to absorb impact and keep its shape instead of retaining damage. ABS is built into the cradle and details in the handle. Likewise, the “soft” characteristic of the Nylon plates protects your floor from damage when using your NUOBELLS. All elements of NUOBELL construction serve a practical function. Our products are engineered with choice materials and tested in Husqvarna, Sweden.

NÜOBELL is the standard model which inspires our partner collaborations. Under license agreements, partners may have modified aesthetic or certain functions that are important for their community of users and resell these versions of NÜOBELL under their own brands.

The NB232 is the KG model with weight range 2-32 kg (sold outside of the U.S. and Canada). The NB580 is the USA & Canada model with weight range 5-80 LB.

NÜOBELL 220 and NÜOBELL 232 are the next generation of FLEXBELL dumbbells. NÜOBELL dumbbells are even more robust than their predecessors due to a refined mechanism in high-quality steel, ensuring an even more controlled total body workout. The second difference is the incremental weight range of 2 kg instead of 4 kg for every “twist and peel”, enabling more variety for a total body workout at home, especially when you are weightlifting with your NÜOBELLs. This change and improvement came partly from feedback from our loyal NÜOBELL community, who communicated that they would prefer a smaller incremental weight increase, particularly when lifting weights over 20 kg. This is one of the many reasons NÜOBELL was named the World’s Best Dumbbells 2021 by Men’s Health Magazine.
