We compared six foldable treadmills under $400 across motor power, folded dimensions, noise level, belt size, and over 27,000 combined Amazon reviews to find the best options for small apartments and tight home gyms. If you live in a space where a traditional treadmill is out of the question, one of these machines will fit your floor plan and your budget.
How We Picked These Foldable Treadmills
Finding the best foldable treadmill for small spaces is not just about the lowest price or the highest star rating. We evaluated each machine across five weighted criteria that matter most when you are working with limited square footage.
Folded footprint. The whole point of a foldable treadmill is that it disappears when you are not using it. We measured how compact each model gets when folded and whether it can slide under a bed, behind a couch, or into a closet. Models that fold flat or upright both made the cut, but we favored machines that take up less than 10 square feet when stored.
Motor power and speed range. A 2.0 HP motor handles walking and light jogging. For anything faster than 6 mph, you want 2.5 HP. We noted the top speed for each model so you can match it to your workout intensity.
Belt size. A running belt narrower than 16 inches or shorter than 40 inches will feel cramped for most adults. We flagged models with smaller belts and specified who they work best for.
Noise level. If you live in an apartment with downstairs neighbors, a loud motor is a dealbreaker. We checked user reviews specifically for noise complaints and called out the quietest options.
Review quality. Rather than relying on star averages alone, we weighted review count alongside rating. A 4.4 star product with 7,700 reviews tells a more reliable story than a 4.8 star product with 200 reviews. Our quality score factors in both.
Across the six treadmills we evaluated, the average rating is 4.25 stars from a combined 27,366 reviews. The most common praise point: easy assembly. The most common complaint: belt length for taller users.
1. UREVO 2 in 1 Under Desk Treadmill: Best Overall
UREVO 2 in 1 Under Desk Treadmill
Best for: Best overall foldable treadmill for home use
The best foldable treadmill under $400 for most people. The 2-in-1 design means you get a walking pad for work hours and a real treadmill for evening workouts.
The UREVO 2 in 1 earned our top spot because it solves two problems at once. Fold the handlebar down, slide it under your standing desk, and walk at 1 to 4 mph while you work. Flip the handlebar up, and you have a proper treadmill that reaches 7.5 mph for jogging sessions.
The 2.5 HP motor is the most powerful in this roundup, and reviewers consistently note that it runs quieter than expected. At 4.5 stars across nearly 2,000 reviews, it has the highest satisfaction rating of any foldable treadmill we evaluated under $400.
The main tradeoff is price. At $369.97, it is the most expensive option on this list. But you are essentially getting two machines in one: a walking pad and a folding treadmill. If you would otherwise buy both separately, this is a clear win.
Who it is for: Anyone who wants a single machine for both under desk walking and dedicated cardio sessions. Especially good for remote workers in apartments.
Who it is not for: Serious runners who need speeds above 8 mph or a wider belt for long strides.
The UREVO 2 in 1 is the most versatile foldable treadmill under $400. The dual-mode design, strong motor, and high user ratings make it our top recommendation.
2. Sunny Health & Fitness Folding Incline Treadmill: Best Value
Sunny Health & Fitness Folding Incline Treadmill
Best for: Best value foldable treadmill with incline
The most proven foldable treadmill under $400. With 7,700+ reviews and a $307 price tag, it is hard to beat on pure value.
Sunny Health & Fitness is a brand that shows up in nearly every budget home gym conversation, and the Folding Incline Treadmill is one of their best sellers. With 7,734 Amazon reviews and a 4.4 star average, it is the most reviewed foldable treadmill on this list by a wide margin. That volume of feedback gives you real confidence in what you are buying.
The standout feature at this price is the 3-position manual incline. Most foldable treadmills under $400 are completely flat. Adding even a slight incline engages your glutes and hamstrings more effectively and burns roughly 15 to 20 percent more calories at the same walking speed. You do have to stop the belt and physically adjust the incline, which is less convenient than a motorized system, but at $307, that is a reasonable compromise.
The soft drop folding mechanism is a nice safety touch. Instead of the deck slamming down when you unfold it, a hydraulic system lowers it slowly. When folded, the machine stands upright and takes up minimal floor space.
Who it is for: Budget-conscious buyers who want a traditional treadmill experience with incline options and do not need under desk functionality.
Who it is not for: Users who want a 2-in-1 walking pad, or runners who need a belt wider than 16 inches.
3. UREVO Foldable Treadmill: Best for Apartments
UREVO Foldable Treadmill for Home
Best for: Best foldable treadmill for apartment living
A solid apartment-friendly treadmill that folds flat and stores easily. Slightly less versatile than the 2 in 1 model but $20 cheaper.
If your primary concern is fitting a treadmill into an apartment without it dominating the room, the UREVO Foldable Treadmill deserves a close look. It folds down to a slim profile that slides under beds, behind doors, or into closets. Transport wheels on the base make it easy to roll from storage to your workout spot and back again.
The 2.5 HP motor matches the UREVO 2 in 1 in raw power, and the speed range (0.5 to 7.5 mph) covers brisk walking through moderate jogging. The LED display tracks the basics: speed, time, distance, and estimated calories burned. Nothing fancy, but everything you need.
The notable difference between this and the UREVO 2 in 1 (our top pick) is the lack of an under desk mode. This is a traditional folding treadmill with handlebars. If you do not need to walk while working, this model saves you $20 and delivers essentially the same motor and speed range.
Who it is for: Apartment dwellers who need a treadmill that genuinely disappears when not in use. Ideal for studios and one-bedrooms.
Who it is not for: Anyone who specifically wants an under desk walking pad.
4. Goplus 2 in 1 Folding Treadmill: Best Budget 2-in-1
Goplus 2 in 1 Folding Treadmill
Best for: Best affordable 2-in-1 treadmill for walking and jogging
A capable 2-in-1 option at $40 less than the UREVO, but the lower star rating and weaker motor make it a runner-up rather than a winner.
The Goplus 2 in 1 offers the same dual-mode concept as our top pick (fold the riser down for walking pad mode, raise it for treadmill mode) at a $40 discount. The built-in Bluetooth speaker is a fun bonus that none of the other models in this roundup include. Pair your phone and play music or podcasts directly through the treadmill instead of wearing earbuds.
The tradeoff is a slightly smaller motor at 2.25 HP versus 2.5 HP. For walking and light jogging, you will not notice the difference. But if you regularly push above 6 mph, the UREVO 2 in 1 will feel more stable and responsive under your feet.
At 4.1 stars across 5,531 reviews, the Goplus is well liked but not quite as universally praised as the UREVO models. Common complaints center around the remote control feeling flimsy and occasional Bluetooth pairing hiccups. These are minor annoyances, not dealbreakers.
Who it is for: Buyers who want the 2-in-1 concept but need to stay closer to $300.
Who it is not for: Users who prioritize motor power and overall build quality over price savings.
5. SereneLife Smart Electric Folding Treadmill: Best Under $310
SereneLife Smart Electric Folding Treadmill
Best for: Best compact foldable treadmill under $310
A solid entry-level foldable treadmill with smart features at a competitive price. Best suited for walkers and light joggers.
The SereneLife delivers smart treadmill features at a decidedly un-smart price. The companion app connects via Bluetooth and tracks your workouts, distance, calories, and progress over time. If tracking your fitness data motivates you, this is a useful feature that most sub-$400 treadmills skip entirely.
Assembly is a strong point. Over 4,200 reviewers have weighed in, and "easy to put together" is among the most repeated phrases. Most users report finishing assembly in under 30 minutes with basic tools. The folding mechanism includes a safety lock that keeps the deck secure when stored upright.
The motor is the weakest link. While the treadmill can technically reach higher speeds, reviewers note it feels most comfortable at walking and brisk walking paces (1 to 5 mph). If jogging is part of your routine, you will likely want the UREVO 2 in 1 or the Sunny Health model instead.
Who it is for: Tech-forward walkers who want app-based workout tracking without spending over $310.
Who it is not for: Joggers or runners who need sustained speeds above 5 mph.
6. Sunny Health & Fitness SF-T1407M Manual Walking Treadmill: Best Ultra-Budget
Sunny Health & Fitness SF-T1407M Foldable Manual Walking Treadmill
Best for: Best foldable treadmill under $100 for walking
At $92, this is the cheapest way to get a foldable treadmill. Perfect for dedicated walkers on a tight budget. Not for joggers.
If your budget is truly tight, or if you only need a treadmill for walking, the Sunny Health SF-T1407M is the most affordable foldable treadmill worth buying. At $91.99, it costs less than a single month of gym membership in most cities.
The catch: this is a manual treadmill. There is no motor. The belt moves because you push it with your feet. This creates a different walking sensation that some people love (it forces you to engage your core and maintain momentum) and some people find awkward. With 5,345 reviews and a 4.0 star average, opinions are genuinely mixed.
Among the SF-T1407M's 5,345 reviews, the most common 5-star praise is "great for the price." The most common 1-star complaint is "hard to get the belt moving smoothly." Setting expectations correctly is key with manual treadmills.
The upside of no motor is significant for apartment dwellers: the machine is nearly silent, weighs less than motorized models, takes up minimal space when folded, and requires no electrical outlet. You can set it up in a hallway, bedroom, or living room with zero infrastructure.
Who it is for: Dedicated walkers on a budget under $100 who want a compact, silent, no-maintenance machine.
Who it is not for: Anyone who wants to jog, run, or experience the smooth belt movement of a motorized treadmill.
Worth it if you exclusively walk for exercise and want the cheapest possible home option. Set realistic expectations about the manual belt feel.
Walking Pad vs Foldable Treadmill: Which Do You Need?
Before you buy, it is worth understanding the difference between a walking pad and a foldable treadmill, since the terms get used interchangeably online.
A walking pad is a flat, motorized belt with no handlebars or console. It slides under a standing desk and typically maxes out at 4 mph. It is designed purely for walking while you work. The UREVO 2 in 1 and Goplus 2 in 1 can function as walking pads when the handlebars are folded down.
A foldable treadmill has handlebars, a console, and higher top speeds (6 to 10 mph). It folds for storage but is a dedicated exercise machine, not a work accessory. The Sunny Health Folding Incline, UREVO Foldable, and SereneLife all fall into this category.
If you want both use cases, a 2-in-1 model is the way to go. If you only need dedicated cardio sessions, a traditional foldable treadmill will give you a more stable platform and often a wider belt.
How All Six Treadmills Compare
The Bottom Line
The best foldable treadmill for small spaces under $400 depends on how you plan to use it. For most people, the UREVO 2 in 1 ($370) offers the best combination of versatility, motor power, and compact storage. If you want incline training at a lower price, the Sunny Health Folding Incline ($307) is the most proven choice with over 7,700 reviews backing it up. And if budget is the primary constraint, the Sunny Health Manual Walking Treadmill ($92) gets you moving at home for less than the cost of a decent pair of running shoes.
Every treadmill on this list folds to a compact footprint that fits in an apartment, spare bedroom, or home office. The right one comes down to three questions: do you need under desk capability, do you want to jog or just walk, and how much are you willing to spend?
