We are thrilled with the bike! My husband wasn’t able to get exercise when the winter weather came but now he rides every day!
Smoother and quieter than the originals. Feels to have better bearings. I’m good with them.

Take your training to the next level with the Marcy Slam Ball — built for athletes, fitness enthusiasts, and anyone ready to unleash explosive power. Whether you’re slamming it into the ground, tossing it overhead, or powering through core rotations, this ball is designed to handle it all. Its dead-weight, sand-filled construction absorbs impact so it won’t bounce or roll away. The rugged tread-textured shell delivers unbeatable grip, even in sweaty sessions.
Available in multiple weights from 10 to 50 lbs (sold individually), there’s a perfect option for every fitness level and training goal — from functional strength to explosive cardio conditioning.
