DeerRun Z10 Pro
A 2-in-1 treadmill that folds to 5.63 inches and still does auto incline. The belt is small, the measured top incline came in at 9% rather than the marketed 12%, and the PitPat app is required to unlock it.
One person can unbox it, fold it flat, and roll it away.
The handrails guide your stride. They do not hold your weight.
$369–$539
