Our treadmills can handle up to 700 Lb user weights without breaking a sweat. We build them from heavy-gage steel and coat them with a polyurea material similar to high-grade truck bed liner. We use steel and lexan to protect the electronics on the display, and a steel hood and foot runners to prevent damage from dropped dumbbells and water bottles.
Our treadmills require almost no maintenance at all. How much is "almost?" Flip the deck every 1-3 years, change the belt every 3-5 years, and change the motor brushes every 3-8 years. Check the drive belt tension after the first 6 months of steady use, and keep an eye on the walking belt so it doesn't get off-center. That's it! That is the entire "maintenance program" for our treadmills. Compare that to ANY other treadmill - you'll see why we're the best - the best choice, the best treadmill, the best in the business!
