Self-Powered Curved Treadmills

Rongle's R800A Swaps Its Motor for 8 Resistance Levels

Rongle's 'R800A' brings self-powered running to home workouts with a curved manual deck and 8 resistance settings that let users shift from free walking to heavier sled-style pushes. 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 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.
