The treadmill has no motor, so the belt responds directly to how fast you walk, jog, or sprint, and it stops when you stop. A magnetic knob adjusts the load without changing machines, which is useful for walkers, joggers, and sprinters sharing one setup. The belt spans 59 x 15.7 inches, and its grippy, cushioned rubber surface keeps footing steady while easing impact on the knees. At $1,349, the R800A is a home option for people who want a [quiet treadmill](https://www.trendhunter.com/trends/victory-treadmill) without the usual motorized setup. Its folding frame and transport wheels make it easier to live with in tighter spaces, while the built-in display keeps core workout stats in view.
