It took over 20 years for our designer Leroy to come up with this brilliant yet simple idea. Many companies have sold capsules for the water over the years, but none of these products could actually move very much on the water. The brilliant idea Leroy came up with is our patent pending sprocket system that we use on the Aqua Treadmill. The sprockets turn this capsule into a human powered vehicle that enables you to move across the water at speeds up to 10mph. You can also steer by putting all of your weight on one side or the other. Once you get tired of moving around you can use the Aqua Treadmill as a floating island with shade. We used a see-through construction for the body of the Aqua Treadmill so you can see where you are going. A high profile with bright colors makes the Aqua Treadmill highly visible on your favorite body of water. Everyone will want one once they see what it can do.
