The belt is available in aluminum or nylon options, with a 1300 mm arc length that mimics natural running dynamics. Paired with a 3.0 mm high-strength tubular steel frame, it supports a 180 kg load capacity for commercial-grade durability. The magnetic resistance system offers 6 precise adjustment levels, accommodating rehabilitation walks to high-intensity sprints. ABS plastic components ensure longevity and tactile operation. Real-time displays track time, speed, and calories. Shipped in a wooden crate for transport safety, this treadmill is engineered for gyms and training studios, delivering a pure mechanical training experience that enhances athletic performance through unadulterated self-propulsion.
