400 vs 450 Lbs Treadmill Specs
Weight Capacity
The primary distinction between these two machines is their maximum load rating. The FOUSAE model supports up to 400 lbs, which accommodates most users seeking a sturdy home workout solution. In contrast, the Joxir unit is engineered with a higher limit of 450 lbs. This extra 50 lbs of capacity provides additional safety margin for heavier individuals or those who prefer a machine with greater structural tolerance. If your body weight approaches the upper limits of standard home treadmills, the Joxir offers more headroom. The FOUSAE remains a robust choice for average to larger users, but the Joxir explicitly targets a heavier demographic with its reinforced design specifications.
Incline System
Both treadmills include incline features, but the implementation differs significantly. The FOUSAE offers a manual 10% incline adjustment. You must physically adjust the central support bolt to change the slope angle. This method is simple but requires you to stop or pause to modify the workout intensity. The Joxir features a 12-level auto incline system. This allows you to change the slope digitally with the touch of a button while running or walking. The Joxir also offers a slightly steeper maximum incline range. For users who want to vary intensity without stopping to adjust hardware, the automatic system on the Joxir is more convenient. The FOUSAE manual incline is effective but less dynamic during active sessions.
Motor Power
Motor strength affects the smoothness and longevity of the treadmill during use. The FOUSAE is equipped with a 3.0 HP brushless motor. This higher horsepower rating suggests it can handle continuous operation with less strain on the components, potentially offering quieter performance at higher speeds. The Joxir uses a 2.5 HP motor. While still powerful enough to reach 7.5 MPH, the lower rating means it may work harder under heavy loads compared to the FOUSAE. However, the Joxir claims whisper-quiet operation below 45 dB. For users prioritizing raw motor durability and sustained high-speed performance, the FOUSAE’s 3.0 HP motor provides a technical advantage. The Joxir’s 2.5 HP is sufficient for walking and light jogging.
Running Surface
The size of the running belt impacts comfort and safety, especially at higher speeds. The FOUSAE provides a running surface of 40 x 16 inches. This width is standard for home treadmills and offers adequate space for most strides. The Joxir offers a slightly larger surface area at 41 x 16.5 inches. The extra inch in length and half-inch in width can make a noticeable difference for taller users or those with a wider gait. The Joxir also highlights a 6-layer anti-slip belt and a 4-point silicone cushioning system for joint protection. While both offer shock absorption, the Joxir’s slightly larger deck and specific cushioning claims give it a slight edge in comfort for longer walks or light runs.
Display and Controls
User interface preferences vary between these two models. The FOUSAE features a large, high-brightness LED display and includes a physical remote control for adjusting modes and programs. This is useful if you prefer tactile buttons over touchscreens. The Joxir utilizes a vibrant RGB LED display with seven color themes, which may appeal to users who want a more modern aesthetic. It also supports app compatibility for virtual training and interactive races. The FOUSAE also connects to fitness apps for tracking data like speed and calories. Both offer countdown modes for time, distance, and calories. If you value a remote control and bright LED, choose FOUSAE. If you prefer app integration and customizable display colors, the Joxir is the better fit.
Which Treadmill Fits Your Needs?
User needing higher weight support
The Joxir supports up to 450 lbs, making it the better choice if you are heavier or want extra safety margin. It also features a 12-level auto incline for varied intensity. The 41 by 16.5 inch running surface is slightly wider than the FOUSAE, offering more room for movement during workouts.
User preferring stronger motor power
The FOUSAE model includes a 3.0 HP brushless motor, which is more powerful than the Joxir's 2.5 HP unit. This provides stable performance at speeds up to 7.5 MPH. It also features 12 HIIT programs and a 10% manual incline, giving you more training options and a robust drive system for consistent jogging.
User wanting app integration
The FOUSAE treadmill connects with fitness apps for virtual training and real-time data tracking. This allows you to monitor speed, distance, and calories burned through a connected device. The Joxir relies on its RGB display and remote control instead. If you prefer guided workouts via an app, this model is the right fit.

Frequently asked questions
Is a 450 lbs capacity treadmill worth the extra cost?
It depends on your body weight and safety preferences. The Joxir model supports 450 lbs, offering a larger safety margin for heavier users. If you are near the 400 lbs limit of the FOUSAE, the 450 lbs capacity provides added peace of mind and durability.
Can a 400 lbs treadmill handle running or only walking?
Both models support speeds up to 7.5 MPH, which allows for jogging. The FOUSAE 400 lbs treadmill includes a 3.0 HP motor and folding frame for home workouts. While designed for app-connected exercise, its speed range supports more than just slow walking.
Which treadmill has better incline features for home use?
The Joxir 450 lbs model features an auto incline system with a handlebar. This allows for varied intensity without manual adjustment. The FOUSAE offers a 10% incline but lacks the automated adjustment found in the Joxir, making the latter better for hands-free incline changes.
Do I need a remote control for these treadmills?
The Joxir 450 lbs walking pad comes with a remote control for convenient operation. This is helpful for adjusting settings while working at a desk. The FOUSAE relies on app compatibility and an LED display, so you do not get a physical remote with that unit.
Which treadmill is better for small spaces?
The FOUSAE 400 lbs treadmill has a folding frame, making it easier to store when not in use. It measures 50 inches long and 22.5 inches wide. The Joxir is a walking pad that is 46 inches long but does not fold, taking up more floor space.
Is the motor power sufficient for heavy users?
The FOUSAE 400 lbs model uses a 3.0 HP brushless motor. This power level supports steady speeds up to 7.5 MPH. The Joxir does not list its motor horsepower in the provided data, but it supports 450 lbs and 7.5 MPH speeds for heavy walkers.
Which treadmill supports under-desk workouts better?
The Joxir 450 lbs walking pad is designed for under-desk use and includes a desk workstation feature. It has a handlebar for stability while walking. The FOUSAE is a folding treadmill with app connectivity, which is less suited for simultaneous desk work compared to the Joxir.
