Motor Power and Performance 

The motor is the heart of any treadmill, dictating its smoothness and longevity.

  • 3.5 HP Treadmill: Its 3.5 HP brushless motor delivers quiet, powerful performance, ideal for intense running or prolonged use. With speeds from 0.6 to 8.7 MPH, it suits walkers and moderate runners alike. The higher horsepower ensures it won’t strain under heavier users or steep inclines.
  • ECHANFIT: Powered by a 3.0 HP motor, it’s slightly less robust but still whisper-quiet and efficient. Its broader speed range (0.5–10 MPH) gives runners an edge for sprinting or high-intensity intervals.
    Winner: The 3.5 HP Treadmill edges out for raw power, while ECHANFIT wins for speed versatility.

Incline and Running Surface

Incline and belt size directly impact workout intensity and comfort.

  • Incline: Both feature a 15% auto incline, mimicking uphill terrain without manual adjustments. The 3.5 HP model’s handrail controls make mid-run changes seamless, while ECHANFIT’s 15-level precision offers fine-tuned customization.
  • Running Surface: The 3.5 HP Treadmill has a 17.4" x 43.5" belt, while ECHANFIT’s 18" x 42.5" belt provides an extra half-inch of width—crucial for taller or broader users. Both include shock absorption (7-layer on 3.5 HP, 8+4 cushioning on ECHANFIT) to protect joints.
    Winner: ECHANFIT takes it for the wider belt, though incline functionality is a tie. Curious about compact alternatives? See "Walking Pad Treadmill with 10% Incline: Compact Fitness for Home and Office Use."
