Motor Power and Speed Comparison
motor power
Motor power defines how long a treadmill can sustain effort without overheating. The Horizon Fitness 7.4 AT features a 3.5 CHP motor, while the Superun Walking Pad offers a 2.5 HP motor. Continuous Horsepower (CHP) measures sustained output, whereas HP often denotes peak output. This means the Horizon motor delivers more consistent torque for running. The Superun motor is sufficient for walking but may struggle with sustained high-intensity intervals. If you plan to run frequently, the higher CHP rating on the Horizon provides better durability and performance stability over time.
maximum speed
Top speed determines whether you can jog or run comfortably. The Horizon Fitness 7.4 AT reaches up to 12 mph, allowing for full-speed running and interval training. The Superun Walking Pad caps at 3.8 mph, which is ideal for brisk walking or light jogging at a slow pace. If your workout routine includes sprinting or high-speed running, the Horizon is the only viable option. The Superun is designed for lower-impact movement, making it unsuitable for serious runners who need higher velocity capabilities for their training sessions.
incline range
Incline adds resistance and engages different muscle groups. The Horizon Fitness 7.4 AT offers an incline range from 0 to 15%, providing significant uphill simulation for hill climbs and calorie burn. The Superun Walking Pad provides a fixed 6% incline. While 6% is effective for increasing intensity during walking, it lacks the versatility for varied hill training. The Horizon allows you to adjust incline dynamically during workouts, offering more control over your resistance levels compared to the static incline on the Superun.
weight capacity
Weight capacity indicates the maximum user weight the machine can safely support. The Horizon Fitness 7.4 AT supports users up to 350 lbs, while the Superun Walking Pad supports up to 300 lbs. Both machines are built with sturdy frames, but the Horizon offers a 50 lb higher limit. If you are closer to the 300 lb mark, both machines will work, but the Horizon provides more margin for safety and stability. For lighter users, both capacities are more than sufficient for daily use without any concerns regarding structural integrity.
intended use
Each machine is engineered for a specific type of exercise. The Horizon Fitness 7.4 AT is intended for running, featuring a 22 x 60-inch deck that accommodates a full running stride. The Superun Walking Pad is intended for walking, with a narrower deck and lower speed limits. If you want to run, jog, or perform high-impact exercises, the Horizon is the correct choice. If you only plan to walk, perhaps while working at a desk, the Superun is better suited for that specific low-impact activity.
