How these alternatives compare
Horizon Fitness 7.4 AT Folding Treadmill
The Horizon Fitness 7.4 AT uses a 3.5 HP motor, which is slightly less powerful than the THERUN’s 4.0 HP unit. However, it offers a much wider 36.6-inch deck compared to the THERUN’s 17-inch belt. This extra width provides more stability for heavier runners. The Horizon weighs 318 pounds, making it significantly heavier and less portable than the 145-pound THERUN. It lacks the THERUN’s 16% auto incline, focusing instead on a robust frame for serious running. Choose this if you prioritize a spacious running surface and heavy-duty construction over steep incline training and easy storage.
THERUN 3.5 HP Folding Incline Treadmill
This THERUN model shares the same TR04 frame and 16% auto incline as the original but uses a 3.5 HP motor instead of 4.0 HP. It supports a 300-pound weight capacity, which is lower than the original’s 400-pound limit. The running surface remains 47.2 by 17 inches, offering identical stride space. It weighs 116 pounds, making it lighter and easier to move than the original 145-pound version. This option suits users who want the same incline and app features but need a lighter machine with a slightly lower weight limit for casual home running.
SereneLife Folding Treadmill with Manual Incline
The SereneLife SLFTRD20 is a budget option with a 1.0 HP motor, far weaker than the THERUN’s 4.0 HP drive. Its top speed is 6 MPH, compared to the THERUN’s 10 MPH, limiting it to walking and light jogging. It features manual incline rather than the THERUN’s 16-level auto incline. The belt is narrower, and the total weight is just 66.5 pounds, making it highly portable. This treadmill is for users who need a compact, affordable solution for light exercise and do not require the power, speed, or steep incline capabilities of the THERUN for serious training.
YPOO Folding Bluetooth Treadmill
The YPOO M4638 is a lightweight folding treadmill weighing 63.9 pounds, significantly lighter than the THERUN’s 145 pounds. It has a 300-pound weight capacity, lower than the THERUN’s 400 pounds. The maximum speed is 8 MPH, which is slower than the THERUN’s 10 MPH. It lacks an incline feature, focusing on flat surface running. The design prioritizes space-saving for small homes. This alternative is best for users who need a compact, easy-to-store machine for light jogging and walking, and who do not need the high power or incline training options of the THERUN.
Merax 3.0 HP Foldable Treadmill
The Merax 3.0 HP treadmill uses a less powerful motor than the THERUN’s 4.0 HP unit. Its top speed is 7.5 MPH, slower than the THERUN’s 10 MPH. It offers manual incline adjustments instead of the THERUN’s 16-level auto incline. The machine supports a 300-pound weight capacity, which is lower than the THERUN’s 400-pound limit. It weighs less and is designed for quiet home walking and light jogging. This option suits users who prioritize a sturdy frame and app connectivity over high-speed running, steep inclines, and maximum weight capacity.
SereneLife 1.0 HP Folding Bluetooth Treadmill
The SereneLife SLFTRD18 is a compact treadmill with a 1.0 HP motor, much weaker than the THERUN’s 4.0 HP drive. It reaches a maximum speed of 6 MPH, compared to the THERUN’s 10 MPH. It lacks an incline feature entirely. The unit weighs only 57.3 pounds, making it very portable. It includes Bluetooth connectivity for app tracking, similar to the THERUN.
