Generally, the more you spend on a treadmill, the sturdier the construction, the more powerful the motor, and the longer the warranty. You can pay $3,000 or more for a nonfolding treadmill that we rated excellent, or half that for a folding model. But even a much smaller investment can buy a decent machine that provides a good workout.
When you’re paying that kind of money for a treadmill, it’s reasonable to expect a machine that works properly. The disappointing news from our latest tests is that manufacturing quality is still spotty. Some models developed problems during our tests that affected their performance. One treadmill didn’t run at all when we got it. Even when repairs are covered under warranty, it’s a hassle.
