Bolt Fitness Revolver Adjustable Dumbbells Review
This product was in-house tested by Michael at The Jungle Gym Reviews.
The Bolt Fitness Revolver Adjustable Dumbbells offer fast weight changes, a traditional round-dumbbell feel, and a wide usable range up to the low-90s in pounds. The biggest advantage is how quickly you can jump between weights compared to plate-loaded systems. The main tradeoff is balance—at lighter and mid-range settings the weight distribution isn’t perfectly even, and the internals aren’t designed to be dropped. These are best for lifters who want speed and convenience without paying premium prices. If you routinely drop dumbbells or demand perfect balance at every weight, you should hesitate.

My Real-World Experience
Day to day, these are about as simple as adjustable dumbbells get. You dock the handle in the cradle, twist to the desired weight, pull it out, and you’re ready to lift. Going from the heaviest setting down to the lightest takes only a few seconds, which is a huge quality-of-life upgrade compared to spin-lock or plate-loaded dumbbells.
The handle feels familiar in the hand. The 34 mm diameter and lightly knurled aluminum grip don’t chew up your palms, but still provide enough traction for presses, rows, and curls. Grip length is adequate even with average to slightly larger hands.
Where you immediately notice a difference from traditional dumbbells is balance. At the lowest setting—essentially just the handle—the weight wants to roll toward the heavier side. As you add plates, it becomes more stable, but it never feels perfectly uniform all the way around. In use, that hasn’t caused issues for me, but it is something you notice if you’re sensitive to balance.
Training Use Cases
These shine for workouts that require frequent weight changes—drop sets, supersets, or shared use between lifters. For presses, rows, goblet squats, and general hypertrophy work, they feel compact enough that range of motion isn’t compromised.
The slight imbalance can actually be used intentionally. Rotating the dumbbell during movements like curls or flies can subtly change where the load feels hardest. That won’t appeal to everyone, but it’s a real-world effect worth understanding.
They’re less ideal for movements where absolute symmetry matters, or for explosive lifts where dumbbells might get dropped.
Tradeoffs & Limitations
The biggest limitation is durability under abuse. These are not designed to be dropped. Plastic internal components help keep cost down, but they also mean you need to treat them with some care.
Balance is the other compromise. Because of the internal half-adder plates and locking system, the weight distribution changes depending on the selected increment. It never feels unsafe, but it also never feels identical to a fixed dumbbell.
You also can’t adjust weight outside the cradle, which means you need to keep the stand nearby during workouts.
Value & Alternatives
At around $800 shipped, these sit in a competitive middle ground. You’re paying for speed and convenience rather than bombproof construction. Compared to other selectorized adjustable dumbbells in this range, the Revolvers offer a traditional round profile and compact size.
If your priority is durability above all else, slower systems with fully metal construction may make more sense. If speed and simplicity matter more, these hold their own in the category.
Who Should Buy This
These make sense for home gym owners who want fast adjustments, a traditional dumbbell feel, and enough weight to support serious training without spending four figures.
Who Should Skip It
If you drop dumbbells, demand perfect balance at every increment, or want lifetime-level durability, this is probably not the right fit.
Final Verdict
The Bolt Fitness Revolver Adjustable Dumbbells deliver speed, convenience, and solid performance for their price. As long as you understand the balance quirks and handle them with care, they’re a practical solution for most home gyms.
