3G Cardio 80i Fold Flat Treadmill

3G Cardio 80i Fold Flat Treadmill: Is It The Best in Class?

3G Cardio 80i Fold Flat Treadmill is quite possibly one of the most impressive folding models around.

Like other treadmills, it can be folded up for storage, but unlike any other, it can be folded all the way down to the floor, making it almost flat and, only 9.75″ high.

The 80i’s folding capabilities are amazing and welcome in houses with restricted square footage, but that’s not all it has going for it.

For example, a motor with 3.0 CHP, a maximum tilt of 15%, and a long warranty.

The 80i Fold Flat is a reliable option if you need a treadmill that can be folded flat after use.

None of the other fold-flat treadmills have a

  • Vertical fold option also.
  • 3CHP motor
  • 15% incline
  • Such a long warranty.

Don’t take my word for it, however; this review will lay out all this treadmill offers so you can make an informed decision. If you read this, you’ll know exactly what to expect from this treadmill and whether or not it’s a good match for your home.

If you’re looking for a high-quality treadmill, look no further than the models made by 3G Cardio. Well-known for treadmills with strong motors and generous guarantees.

The 80i Fold Flat is one of their four treadmills with one of the most reasonable prices.

The 80i is a modestly priced treadmill, so it is missing some of the more advanced features you may find on more expensive models (and the console also looks a little dated).

But if you want a treadmill that can be folded up and rolled under a couch, you’re thinking in the correct direction (if that makes any sense).

3G Cardio 80i Fold Flat Treadmill – Pros & Cons


  • The frame may be folded in both directions.
  • It keeps well in a concealed location.
  • Driven by a 3.0 HP motor.
  • Capable of supporting up to 325 pounds.
  • Change the gradient and speed with a single touch.
  • Simple dials for adjusting the pace.
  • The product requires zero assemblies and is ready to use right out of the box.
  • A solid guarantee.
  • A+ service to the consumer.


  • Those of greater stature(6′ or above) may find the running area to be a little cramped.
  • There’s a lack of Bluetooth support.

3G Cardio 80i Running Track

20′′ x 60′′ is the industry standard for home treadmill running surfaces. Most people won’t have to alter their stride length when sprinting on this sized track.

The 80i’s track dimensions are 18.5′′ x 58′′. But none of the push-under-the-bed or work-while-walking treadmills has such a big track.

Although it is noticeably smaller than other treadmills in its price range, I suspect its compact size was designed with portability in mind. Most users should be able to stroll about freely on the 80i, while those who are very tall(6′ feet & above) may have some difficulty when running, especially at faster speeds.

The treadmill’s construction is surprisingly sturdy for something so lightweight. For accuracy’s sake, it’s sturdy enough to support up to 325 pounds.

While many modern treadmills fold vertically, only a small percentage fold horizontally (and flat to the ground). Most treadmills fold up vertically, with the deck coming up to meet the control panel.

Similarly, the 80i can be folded either vertically or horizontally, offering you more space for storage when it’s not in use.

3G Cardio 80i Motor

Powering the 80i is a 3.0 HP motor that allows for an 11 mph peak speed and a maximum incline of 15%.

To run, motor strength is more crucial. A more powerful motor will also help you walk more efficiently.

A more powerful motor requires less effort to maintain the same speed as a weaker motor. In general, a stronger motor will last longer, run more quietly, and make the experience more enjoyable.

If you want to run, you should get a motor with at least 3.0 horsepower so that you have enough power to get up to speed and stay there.

It’s close, but the 80i manages to pass muster here. This treadmill’s 3.0 HP should be more than adequate for the majority of runners. Its functionality is generally well-received by its users.

Serious runners could benefit from a treadmill with higher horsepower. Also, sprinters may be let down by the top speed of 11 mph (albeit it’s still far quicker than I can manage).

In this version, the rollers are 2 inches in diameter, a feature that 3G Cardio is known for. They’re not too far off; premium treadmills often have rollers that are 2.5 inches in diameter.

The belt rides more smoothly on larger rollers because they have a greater surface area with which to make contact (it also increases the lifespan of both the rollers and the belt).

The 80i features a respectable motor that should be enough for most everyday needs. Those who run or sprint competitively should think about upgrading to more robust equipment.

3G Cardio 80i Features

Included in the package of the 80i Fold Flat Treadmill are:

  • This treadmill has eight pre-set routines and four user-defined programs for you to pick from. This isn’t a huge selection, but it will do the trick.
  • Quickly adjust your pace or slope with a single press of a button, eliminating the need to fumble through the menus. It is particularly helpful for interval training.
  • Connect your iPhone or MP3 player to the console’s mp3 connector and enjoy your music via the system’s built-in speakers.
  • The treadmill’s speed dial is conveniently located and enables speed selection with a quick turn of the knob. It is better than using the up and down arrows, which are a bit more cumbersome. A display that can actually “fold flat,” as 3G Cardio puts it. The treadmill’s control panel may be folded flat along with the rest of the equipment for simple storage. When laid flat, the height is 9.75′′.

3G Cardio 80i Assembly

The 80i requires zero assemblies since it is delivered fully put together. Simply unfold it and store it away. Done. Put away your toolbox.

Don’t even consider spending money on so-called “professional assembly.” The treadmill weighs in at about 225 pounds, so bear that in mind.

3G Cardio guarantees the 80i Fold Flat

  • Life Time on motor and frame.
  • 5 years on parts
  • 1 year of labor

The treadmill has a fantastic category-leading guarantee.

In this price range, parts usually come with a five-year warranty, but this isn’t always the case.

Also common is a one-year guarantee on labor, but some businesses go as high as two years (3G Cardio offers 2 years on their most advanced treadmill).

As a whole, I believe this is a very solid warranty for a treadmill.

Final verdict

Athletes will be ecstatic to learn that they can fold this treadmill and stow it away under a bed without sacrificing the quality of their running session. Unfortunately, the belt on the vast majority of foldable treadmills can’t even be accelerated to a brisk walk, let alone a jog. With a peak speed of 11 mph, this one allows for some serious running. The ability to incline is another feature often sacrificed in foldable treadmills. The 80i Fold Flat is a high-performance treadmill with incline options ranging from 0% to 15%.


  1. Can a treadmill be folded up such that it fits beneath the bed?

The 80i Fold Flat Treadmill is a space-saving and highly effective treadmill that can be folded up when not in use. Because of its clever design, the treadmill can be folded both vertically and horizontally. This makes it easy to store under a bed when it’s not in use.

  1. How much weight can this device support?

Its maximum user weight is 325 lbs.

  1. Is there a need for assembly?

The answer is no, you don’t need any special equipment or tools to put it together. The treadmill ships folded up and are only to be unfolded when it is received. The only real difficulty may be getting it into the room since it is rather heavy due to its sturdy construction.

  1. Does this device display heart rate when using a chest strap, and does it feature aerobic workout options?

Though it can measure heart rate manually, it is unable to interpret data from a wireless chest strap. The 80i is the only 3G Cardio treadmill that cannot read a wireless chest strap.

  1. To what extent can I fold down the console’s screen and still use it? In that case, how tall is it? Will it be perfect for my standing desk?

When the upper console is folded down, the distance from the ground to the top of the “The 45” height includes the “folded” console. Of course, you can still run on the treadmill, and the fact that you can adjust the incline and pace is even better news. Toggle switches are located on both sides of the top handrails, freeing you from the need to use the centre console for adjustments. Better yet, you can use the folding console as a treadmill desk if you purchase a big mouse pad. A mouse pad might help prevent the laptop from moving about while in use.

  1. For storage purposes, what are the treadmill’s folded footprint dimensions?

The dimensions of a folded 3G Cardio 80i fold flat Treadmill are 74″ (length) x 33″ (width) x 9.75″ (height)” (height from floor to top of the treadmill). I really hope this is of some use!

  1. In colder areas, is it safe to use a treadmill in a garage?

I don’t see why not, as long as the oil on the moving components doesn’t freeze.
