Endurance motors are designed to exceed horsepower and performance standards for home-use treadmills. Each motor is protected by P.W.M. (Pulse Width Modulation) technology and air-cooled for efficient performance. The integrated circuit breaker protects the motor and control boards from power surges. * Bright LED displays let you monitor your running track and provide you with constant feedback on your workout, including heart rate, elevation, time, distance, speed and calories burned. * Large Diameter Crowned Rollers. Casehardened steel rollers feature a large diameter design with a wide-radius crown to drastically decrease wear, substantially increase surface contact and provide superior belt tracking. * Safety Key Stop System. Endurance treadmills will only operate when the safety key is engaged on the control panel. This gives you the ability to instantly shut down operation if you need to. * Quiet Performance. The Endurance Poly-V Belt Drive System delivers an amazingly quiet workout experience, allowing you to watch TV or read a book without being distracted by machine noise. Construction: * Rigid Steel Frame Construction. Heavy-duty 2"" x 3"" and 2"" by 4"" steel frame construction delivers a rock-solid platform for hardcore cardio workouts. The Endurance TF3i is built to withstand constant pounding and jarring.
