Key Differences Between Models
Motor Power
The FUNMILY 4.5HP Folding Treadmill with 20% Auto Incline features a 4.5 HP motor, while the FUNMILY 3.5 HP Folding Treadmill with 15% Incline uses a 3.5 HP motor. A higher horsepower rating generally supports more consistent performance during vigorous running sessions. The 4.5 HP unit is designed for demanding cardio, whereas the 3.5 HP model is optimized for walking and under-desk use. If you plan to run at higher speeds, the stronger motor in Product B provides better durability and power reserve. For casual walking, the 3.5 HP unit is sufficient.
Incline Range
Product B offers an automatic incline range from 0 to 20% across 15 levels. Product A provides a manual incline option with settings at 12% or 15%. The 20% maximum incline on the 4.5HP model allows for steeper hill simulations, which target quads and glutes more intensely. Product A’s incline is limited to 15% and lacks automatic adjustment. If you want to vary terrain difficulty without stopping to adjust handles, Product B’s auto-incline feature is superior. Product A is better if you prefer simple, fixed incline levels.

The FUNMILY 3.5 HP Folding Treadmill with 15% Incline does not list a maximum speed in its published specifications.

If your workout includes jogging or running intervals, you need the verified speed data found in Product B.
Display and Tracking
Product B includes a large LED display and dual health monitoring with real-time heart rate tracking via handle sensors. It also measures body fat. The FUNMILY 3.5 HP Folding Treadmill with 15% Incline does not list a display type or health tracking features in its data.

For users who prioritize data tracking during their workout, Product B is the better choice.
Dimensions and Stability
Product A is 54 inches long, 26 inches wide, and 5.9 inches high. Product B is 53.9 inches long, 26.7 inches wide, and 9.1 inches high. Product A includes a handlebar for stability, which is useful for under-desk walking.
