The NÜOBELL 80 is the closest an adjustable dumbbell has ever come to replacing a commercial 16-pair dumbbell rack: twisting the 32mm knurled handle shifts weight in 5 lb increments instantly, and the flat ends sit comfortably on your thighs before heavy presses.
What We Liked
- Patented twist-to-adjust handle changes weights in less than 2 seconds without reaching for dials or pins
- Flat dumbbell ends sit flush on your thighs during setup for bench press or shoulder press without gouging
- Dumbbell length scales dynamically with the weight: at 20 lbs it measures only 9.5 inches instead of full length
- Machined 32mm knurled steel handle provides an authentic barbell-grade grip without tacky rubber
- 16 distinct weight settings in consistent 5 lb increments from 5 to 80 lbs per hand
- Compact footprint replaces an entire 7-foot commercial dumbbell rack in a 17-inch cradle
What Could Be Better
- Internal selector gears contain nylon components: not rated for intentional drops onto concrete
- Top-tier $845 pricing reflects premium machining and high market demand
Why It Stands Out in Our Analysis
For decades, adjustable dumbbells forced lifters to choose between cumbersome cages (PowerBlock) or sluggish end-cap dials (Bowflex). The Swedish-engineered SMRTFT NÜOBELL revolutionized the category by embedding the entire selector rod inside the center shaft: you simply place the dumbbell in its machined cradle, rotate your wrist until the numeric window shows your target weight, and lift.
Its biggest ergonomic breakthrough is dynamic length scaling. Unlike older dumbbells that remain 16 inches wide even when set to 10 lbs, the NÜOBELL leaves unselected plates behind in the cradle. When curling 25 lbs, the bell is compact and agile, avoiding awkward clashing against your hips during curls or lateral raises.
Sibling Trim Breakdown (NÜOBELL 80 vs. NÜOBELL 50): SMRTFT sells both a 50 lb and an 80 lb variant. We strongly advise against the 50 lb model: because the internal selector rod cannot be expanded after purchase, owners who start with 50 lbs and progress quickly are forced to buy an entirely new 80 lb pair. Spending the extra ~$150 upfront gives you 160 lbs of total load that will last years of progressive overload.
Intermediate to advanced home gym lifters who prioritize fast set transitions, traditional dumbbell ergonomics, and flat thigh-resting ends for heavy pressing.
While the plates are solid machined steel, the central indexing teeth inside the handle use reinforced composites; re-rack them into the cradle with care rather than dropping them from waist height.
