Fits just right over the handles. Nice and snug. Keep in mind, since the ends are dumbbells and not normal weights (where the weight would be centered on the bar) any movement or rotation of the bar feels different/strange compared to a normal barbell. This is because these being dumbbells on the ends, the weight extends beyond the center of the bar unequally (as opposed to a regular barbell where the weight is over the bar evenly around the bar because its in a circle). So any natural rotation of the bar creates momentum that you feel in your hands. Didn’t expect that, but makes sense and should be expected. It’ll be something to get use to. You’ll understand what I mean when you start using them. Otherwise, seems to be the next best thing to having an actual ez-bar and now I have more uses for my dumbbells and more exercises to work with. Review: Quick, Easy, Silent, Perfect - Perfect addition to my gym. I've recently downsized the equipment I use, now with the Hyperbell Straight Bar, EZ Curl and Kettlebell I can fully utilize the dumbbells I have. I also us some magnet add on weights, that attached to the dumbbells to make increasing set weight quick and easy and maximize the workout. Silent---No rattling plates to wake up the family on those early or late night quick pump sessions. Love it. Strong. Easy to use. Great Customer Service. ## Features - CONVERT TO AN EZ BARBELL CURL BAR: Easily transform your dumbbells into a curl bar with the EZ Curl Bar adapter, expanding your workout options and saving you space - LESS STRAIN, MAX GAIN: The EZ curl bar allows for a more comfortable bicep curl bar, with an angled grip that reduces wrist tension, making it one of the best preacher curl bar for weight lifting - GYM-LEVEL DURABILITY: With a 200lb weight capacity, the Hyperbell EZ Curl Bar 1 inch can handle serious weight lifting workouts, and is made with high-strength modular plastic clamps that have been drop-tested to meet olympic curl bar standards - VERSATILITY: This dumbbell bar is compatible with most standard dumbbell handles up to 1.5" thick and a minimum of 4.5" long, making it one of the most versatile weight bars for lifting on the market - AT-HOME WORKOUTS: Whether you're working out at home, in the gym, or on the go, the EZ curl barbell is the perfect exercise equipment for bicep curls, tricep extensions, skull crushers, and other strength training exercises.

The EZ Curl definitely works with Bowflex 552 but seems to be hit or miss with 1090s. We think Bowflex changed their handle measurements so we would definitely recommend measuring the width prior to purchasing. Your dumbbell handle length must be at least 4.5” long to accommodate the width of the Hyperbell Bar clamps. (Most are 6”.) Lastly, the diameter of your dumbbell handle can be no bigger than 1.5” at its thickest point. **Q: Hi will this work with Bowflex 560 select tech dumbbells?** A: HYPERBELL works with almost all regular and adjustable dumbbells. However, there are some limitations. The length of the dumbbell handle needs to be at least 4.5" long. Most dumbbell handles are approximately 6.0" long. The diameter of the dumbbell handle needs to be less than 1.5" at its thickest point. The foam insert inside the HYPERBELL will contour to both straight and curved dumbbell handles. HYPERBELL is compatible with hex dumbbells, Bowflex SelectTech Adjustable Dumbbells (552 and 1090), CORE Fitness, Peloton, JaxJox, MX Select, Merax, Weider, NordicTrack (orange version) and many others. HYPERBELL is not compatible with PowerBlock, NordicTrack (blue version) or Nuobell dumbbells. **Q: Will this work with powerblock adjustable dumbbells?** A: No. Powerblocks have a cage which obstructs the Jayflex clamps from attaching. Also does not fit NuoBells, as the grip area is too narrow. **Q: Is this compatible with nobull adjustable dumbbells?** A: Hi John, the HYPERBELL Bar is not compatible with Nuobells. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works on Nonzero Gravity Power Dyne Adjustable Dumbbells *by J***A on May 22, 2023* Works well on Nonzero Gravity Power Dyne Adjustable Dumbbells (also bought on Amazon).

Great Customer Service. ### ⭐⭐⭐⭐ Almost perfect *by N***T on June 15, 2024* This is a brilliant piece of equipment however there’s one specific thing that stands out that could be better. The grips for the dumbbells are nice and hold them tight (they do only work with cap dumbbells as I’ve tried others and it will not fit. My main observation is that the collars that screw on the grips for the dumbbells are plastic and not very thick plastic at that. They are a major weak point in the design. If the collars were metal instead this would be a perfect design but instead they’re rather thin plastic and for the price of this it’s going to be a point of failure eventually in an otherwise stellar piece of equipment. Here’s hoping they sell replacement collars. ## Frequently Bought Together - Jayflex Hyperbell Dumbbell Converter - Convert Dumbbells to Barbell Set and Kettlebell for Home Fitness - Adjustable & Up to 200 lb Capacity Weight Barbell for Weight Lifting - Amazon Basics Rubber Hex Dumbbell Hand Weight - CAP Barbell Coated Dumbbell Weight | Multiple Options Pairs & Sets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/525936651-jayflex-hyperbell-dumbbell-converter-convert-dumbbells-to-barbell-set-kettlebell](https://www.desertcart.tw/products/525936651-jayflex-hyperbell-dumbbell-converter-convert-dumbbells-to-barbell-set-kettlebell) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-06-05*
