A good-quality treadmill should last at least 7 or so years, even with very heavy use. Many users report owning treadmills that last well over 10 years. Before you buy, check the treadmill’s warranty.
On this list, the Sole F63 Treadmill is our pick for the best budget treadmill warranty because it is backed by a lifetime warranty for the frame and motor. It also has a solid 3-year warranty for the running deck.
