About Kewlus: World's First Modular Boxing Training System

I’m Reedy Kewlus, engineer, inventor and lifelong DIYer. I turned my passion for homemade boxing gear into the world’s first fully modular reflex punching-bag system. Precision-engineered for rock-solid reliability and pro-level performance, Kewlus delivers fast, snappy rebound and a setup that adapts seamlessly to any space or training goal.

At the heart of Kewlus is its swap-and-upgrade architecture: every component is 3D-designed and crafted from premium materials such as signature-alloy springs and fiber-composite parts that ensure optimum performance, durability and versatility. Embraced by an ever-growing network of boxing gyms and coaches, it’s built to last decades, cutting waste and saving you money by eliminating one-and-done gear.

Owning a Kewlus means having a lifetime-ready system that grows with you. From beginners as young as five to seasoned fighters and fitness enthusiasts of every level, your setup evolves as your skills evolve. Swap springs, swap targets, or swap nothing at all, and keep pushing your limits on your own terms.
