Quick verdict
LiftEvidence editorial assessment
A folding treadmill with a 3.5 CHP continuous-duty motor, a 22 × 60 in running surface with three-zone cushioning, 0–15% incline, 12 mph and a 350 lb user rating. It is one of few machines here that publishes a continuous motor rating, and it works fully without a subscription, connecting to third-party apps instead. Owner feedback on reliability and assembly is mixed.
