Can this be used with the Bowflex SelectTech 552 or 1090 adjustable dumbbells?

Hi there! 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.

Hi will this work with Bowflex 560 select tech dumbbells?

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.

Will this work with powerblock adjustable dumbbells?

No. Powerblocks have a cage which obstructs the Jayflex clamps from attaching. Also does not fit NuoBells, as the grip area is too narrow.

Is this compatible with nobull adjustable dumbbells?

Hi John, the HYPERBELL Bar is not compatible with Nuobells.

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.

This is great when it works. But gets quite flimsy for weights exceeding 20kg. I’ve had this for 18 months, and the poor thing died after just doing KB swings with a 20kg weight. I can’t seem to find any information on a warranty. I think I’ll be looking for a more solid solution in future.
