For Serious Training & HIIT
Pick the Rellfit lineup for running if you're open to exploring, but with 0 dedicated HIIT/running models available, I'd hold off—none hit the mark for proper motor power or speed. Rellfit's aggregate stats show 0HP motors and 0-0mph ranges, so they lack the basics for sprints or intervals. No alternatives stand out here; consider other brands like NordicTrack for real options in the $500-$1,000 range with at least 2.5HP and 10-12mph capabilities.
✓ No motor power: 0HP limits any running or HIIT use
✓ Zero speed range: 0-0mph means no pace for even basic jogging
✓ Budget empty: $0-$0 range reflects no viable models for serious workouts
❌ Who it's NOT for: Anyone needing actual running gear—this has zero suitable options for HIIT or cardio.

How Does Rellfit Compare to Other Treadmill Brands?
Rellfit offers just one folding treadmill model with a consistent 3HP motor and 8.7mph top speed, positioning it as a compact choice for home running in small spaces. Compared to competitors like Sunny Health & Fitness, which provide multiple walking pads with 1-2HP motors and speeds up to 6mph, Rellfit excels in power for joggers. Brands like NordicTrack focus on feature-rich commercial units with app integration, but Rellfit prioritizes straightforward, space-saving reliability for daily use.
Rellfit stands out as a niche player in the home treadmill market, offering just one model at a striking price range of $0-$0, which positions it as potentially the most accessible option for budget-conscious buyers or those testing entry-level fitness gear. With a focus on essential features like a 3.0HP motor, full foldability (1/1 fold design), and smart integrations such as app voice control and Bluetooth speakers, Rellfit targets space-saving home setups for casual runners. Unlike broader competitors flooding the market with dozens of variants, Rellfit keeps things simple and specialized, emphasizing auto incline up to 15% and a 350 lb capacity without the premium markup.
The Rellfit Treadmill with Auto Incline 15% - 350 Lb Capacity - Foldable - 3.0HP Running Treadmill for Home compares favorably to budget rivals like Goplus, which offers similar 3HP motors but often at $200-$300 with fewer smart features—Rellfit edges out with adjustable handrail height and voice app control that Goplus lacks in its basic folds. Against NordicTrack's high-end models averaging 3.5HP+ and $1,000+, Rellfit's single 3-3HP offering shines for light jogging at zero cost barrier, though it can't match ProForm's wider speed ranges. Overall, Rellfit's foldable design holds its own in the compact segment where competitors like FUNMILY provide comparable capacities but without
