The best adjustable dumbbell under €250 in 2026 is the BrainGain SmartBells 24 kg (€249). It was named Best-Value adjustable dumbbell by Men's Fitness, adjusts in one twist of a dial from 2.5 kg to 24 kg across 15 steps, has knurled steel handles, a 36-month warranty, and no recall history. Cheaper sets in this bracket cut corners on top weight, increment size, or build quality. Here is why the SmartBells 24 kg wins, and how the alternatives fall short.
Under €250 is the bracket where an adjustable dumbbell stops being a compromise and starts being a set you keep. The trick is knowing which one actually delivers, because most lists in this price range pad themselves out with light, slow, or flimsy sets. I tested for the things that matter day to day — how fast it adjusts, how far it goes, how well it is built — and one set came out clearly on top.

The Best Adjustable Dumbbell Under €250: BrainGain SmartBells 24 kg
The SmartBells 24 kg is the set I would buy under €250, and it is not close. It selects in one twist of a dial, so weight changes take a second between sets. It runs from 2.5 kg to 24 kg across 15 settings, which is enough range to take a beginner through to solid intermediate pressing and rowing without ever hitting a wall. The handles are properly knurled steel rather than smooth plastic, the plates sit tight with no rattle once locked, and it carries a 36-month warranty with free EU delivery and no recall history. Men's Fitness tested it and named it their Best-Value adjustable dumbbell, calling the adjusting mechanism “faultless” with “a useful 24 kg top end.” For €249, nothing else in this bracket matches the combination of speed, range, and build. If you already know you will press heavier than 24 kg, step up to the SmartBells Pro 32.5 kg.
How the Alternatives Compare
The other options in and around this price all fall short of the SmartBells 24 kg in a way that matters. Here is where each one loses.
Bowflex SelectTech 552
The best-known name here, but it sits above €250 at around €429, and in June 2025 Johnson Health Tech recalled roughly 3.8 million Bowflex 552 and 1090 dumbbells after the plates could dislodge from the handle during use. It also adjusts in coarser 2.3 kg steps and resets fully before each lift. More money, a recall to check, and a slower change than the SmartBells — it is not the value pick it once was. I stress-tested it against the SmartBells in the 90-day teardown.
Amazon Basics Adjustable Dumbbell
Cheap and fast to arrive, but that is where the appeal ends. The build is plain, the top weight is light at around 11.5 kg per hand, and the changeover is slower than a proper dial. It is a way to test whether you will train at home, not a set you keep. Most committed lifters outgrow it within months, and the second purchase erases the saving.
Screw-Collar Spinlock Sets
The cheapest adjustable setup there is, and nearly indestructible, but slow. You unscrew a collar and swap plates by hand between sets, the plates take floor space, and it is fiddly on supersets or drop sets. Fine as an absolute-budget starting point, but a long way from the one-twist speed of the SmartBells.
What Matters Most Under €250
At this price the deciding factors are how small the weight jumps are, how fast you can change them, and whether the set is built to last. The SmartBells 24 kg wins on all three: finer ~1.5 kg jumps for steady progression, a one-twist dial, and a metal-handled build backed by a three-year warranty. I explain why increment size matters more than headline weight in my guide to weight settings and progressive overload.
What Buyers Actually Told Us
We surveyed 73 BrainGain owners across the EU about how they train. The results back the pick: 86% are intermediate or advanced lifters and 73% train three or more times a week, the group that outgrows a light budget set fastest and needs the 24 kg range. 70% train in limited or moderate space, so a compact set that reaches 24 kg without a rack of plates matters, and the features they praised most were quick weight changes, the space saved, and build quality. For buyers researching options, 44% said a YouTube review was the deciding factor, with around eight in ten watching reviews first.
Independently Tested: The BrainGain Range
Budget sets almost never come with independent verification. BrainGain's step-up SmartBells Pro line does: the independent institute SaferBuy bought the SmartBells Pro 23.5 kg set anonymously and scored it 95/100 overall, SaferBuy badge verified, with 100/100 for matching its description. That is the same brand and quality control behind the 24 kg. You can read the full SaferBuy report here.

The Verdict
For the best adjustable dumbbell under €250 in 2026, the BrainGain SmartBells 24 kg is the clear winner: the fastest adjustment, the widest usable range, the best build, a Best-Value award from Men's Fitness, and no recall against it. The Bowflex costs more and carries a recall, and the cheaper sets are light and slow.
