Nautilus T618 Overall Quality


The Nautilus T618 folding treadmill has an upgraded 3.5 CHP motor that provides smooth performance and speeds of up to 12 MPH for those who like to sprint during interval training. While the belt remains the same roomy 20” x 60”, it is slightly thicker, and the rollers are a tad bit larger in the T618 design. Users can incline up to a 15% elevation while enjoying the newly patented rebound suspension system that softens the landing at the front of the deck while causing a rallying effect on impact that pushes users forward into their next stride or running pace. It is quite clever and keeps energies high.
