The ingenious design allows a user to not only fold the treadmill upright but also fold the treadmill flat to the floor and stored away under a bed. When folded flat to the floor, the 3G Cardio 80i Treadmill has an extremely low height of only 9.75″.
With the all new 3G Cardio 80i Fold Flat Treadmill design, it is now possible to fold the treadmill flat and wheel it under a bed or shelf or simply roll it through a doorway. While there are other folding treadmills on the market, none will match up in ease of use and overall quality.
Thanks to the 3G Cardio 80i Fold Flat Treadmill, getting a cardio workout through walking or running has never been easier or more economical. The 3G Cardio 80i Fold Flat™ Treadmill delivers a triple play that will be a hit with people of nearly all ages and fitness levels:
Starting with a heavy duty 3.0 HP motor, nearly a 60” running surface and the stability of a treadmill twice its price, the 3G Cardio 80i Treadmill will impress even the stingiest of runners. With a capability of reaching 11mph maximum speed and Incline: 0 to 15 levels, it would be very tough for someone to outwork this treadmill.
3G Cardio 80i Fold Flat™ Treadmill will fit into just about any schedule, or space. There are few things better, or more natural for a person to do than walking or running. Unfortunately, not all of us have the time or indoor space to walk, run, or do both, as much as we’d like.
The 3G Cardio 80i Fold Flat™ Treadmill is the only “fold flat” treadmill in the market today that is built for running. All others are built for walking and there is also no other treadmill on the market today that can fold both flat and vertically!
The 3G Cardio 80i Fold Flat™ Treadmill features audio hook-ups for an MP3 Player, iPhone and built-in speakers.
The 3.0 HP motor is the most powerful on the market for a Fold Flat Treadmill. It also has a heavy duty frame and belt, which enables it to be rated for use by people weighing up to 325 pounds.
If you have any questions or problems with the 3G Cardio 80i Fold Flat™ Treadmill, it is reassuring to know that this treadmill has one of the best warranties available; 5 years parts, one year labor, lifetime guarantee on motor and frame. In a word, impressive!
With the 3G Cardio 80i Fold Flat Treadmill, you can conserve space and still get a great workout. The 3G Cardio 80i Fold Flat Treadmill has a low step-up height of just 6 inches, meaning your feet are closer to the floor and you’ll be farther away from the ceiling than on most other treadmills. Those few inches the 3G Cardio 80i Fold Flat Treadmill saves can make a big difference in small spaces.
If you are tight on space and still want a treadmill, the 3G Cardio 80i Fold Flat Treadmill is the only “under the bed tread” that will support you well enough to get a good running workout.
If you prefer, fold the treadmill vertically and store in corner of a room, closet, etc.
The 3G Cardio 80i treadmill belt offers the stability of a treadmill nearly twice its size and will even impress experienced runners.
The biggest difference one will notice with the 3G Cardio 80i Fold Flat Treadmill compared to other fold-up treadmills is its power and stability. It has a heavy duty 3.0 HP motor and a running surface of nearly 60 inches, providing the stability of a treadmill nearly twice its size that will even impress experienced runners.
The vast majority of fold down treadmills don’t allow users to go past 4 mph, but the 3G Cardio 80i fold down treadmill has speeds that range from 0.5 to 11 mph.
The 3G Cardio 80i can be set for a Incline: 0 to 15 levels. Most fold down treadmills are meant for low-impact walking and will feel extremely slow and flimsy if you try to run on them.
A 325-pound user weight maximum capacity is extremely high for fold flat treadmills.
There’s a good deal of stability when running, but the machine is light enough too also be easily folded up and rolled away for storage.
The 3G Cardio 80i Fold Flat Treadmill also has some of the best “extras” among fold flat treadmills. It features built-in speakers that you can hook an iPhone or MP3 player up to.

Very Happy –
I have now owned my 80i treadmill for about 3 months and am very satisfied with my purchase. I also want to tell 3G Cardio that you guys are doing an injustive by not adding more product images to your website. The best feature of this treadmill is that it can fold up or down and once folded down, it is actually really easy to roll! I needed a fold flat treadmill so I would roll it under my pool table when not using it and I was concerned that I would have to lift the treadmill up really high to engage the wheels and that is not the case. I only have to lift the back of the treadmill about 8″ to engage the wheels. With that said, I was hoping I would get a treadmill that was solid and felt stable when I was running on it and it is both of those and then some. The upper electronics does everything I need and the audio speakers sound decent enough, the cushioning is soft and the motor feels strong. I weigh 205 lbs and was concerned the treadmill would feel flimsy. Again, not the case. Over all, I rated this treadmill 5 stars and again, add more pictures to your website so other potential customers can see the really cool stuff!
I have to say that I am really surprised there are not more product images on your website.

I rated this treadmills 4 out 5 stars. Very cool that this treadmill folds up and folds down to the ground. Although I am too old and fat to run, I have jogged on it and it feels very stable. There is plenty of room to walk and run if you want, the choice of programs is good too. This treadmill does exactly as advertised and so far so good. No problems.

I would give 4 1/2 stars if I could; the value (quality &; usefulness vs expense) is very high.
The 80i is stable & comfortable for a 180lb runner up to 10mph (haven’t worked up to 11mph yet).
The size is perfect – that is, as small as possible to still be comfortable & safe at high speed. Not exactly quiet, but as quiet as all but the most expensive gym treadmills.
The incline is very good.
Controls are good:
– the rocker switch on the right handrail (.1 speed increments per toggle) is especially handy.
– the speed & incline one-touch buttons are very useful as well.
– the quick dial wheel is fun but not often used; I would rather use the space for a smartphone slot – which the 80i needs.
The fold feature is about as good as I can easily imagine (though still waay too high to go under a bed). The 80i is not easy for a 100lb female to move, though easy enough for a 180lb male.
– The speakers are not used.
– The programs are not used
The heartbeat monitor is useless at much over 100bpm (as are almost all such monitors), it’s a waste.
The Displayed speed leads the actual speed by a large amount for a long time when adjusted: eg going from 4 to 8 mph takes well over 30 seconds, but the display reports you’ve reached 8mph in less than 15 seconds. I would like to see the set speed and actual speed separately.
Love this treadmill, the controls are easy to use. The fold up/down process is simple and I don’t worry about it falling down! It is quiet and is one of the better quality home treadmills I’ve used. Great customer service, had to call for a silly reason, couldn’t find the on/off switch! They were nice and helped me in one minute. Overall, great experience!
We rated the Cardio 3G 80i a top-pick for apartment living because it folds flat and you can get creative on where to store it if you have a tight living space. It can go under the bed or vertically next to a wardrobe. We like it’s no-frills approach and the fact that it is also full-featured with programs, speakers and a powerful motor.

This is a review from a resident of New York City purchased in a Covid -19 world. I needed a treadmill I could have delivered and left outside my apartment, so that I could open it up and roll it in without any help moving or assembling in my home. It worked perfectly for this; in spite of the size and weight of the box I was able to rip the box open, stand it up, and move it without any help. It is a very stable, sturdy machine that I have been running on regularly. I am used to running on a large, expensive treadmill in the gym and this works just fine for a home unit. Nothing fancy, no large color screen or video instructors shouting at you what to do, just the necessary basics at a very fair price. Customer service has been fantastic. Bryan answered all of my questions about the unit and once ordered provided help with the box’s long journey and dealing with a trucking company unwilling to drive into the city. I had looked at every treadmill available in the U.S.. If you are looking for a unit that is not a toy but a real, solid treadmill, that can be delivered and set up without any assistance, this is definitely the best choice.
I needed a treadmill that doesn’t take up much room in my small apartment and I’m really happy with the 3G Cardio 80i Fold Flat Treadmill. I’m a 5-foot-2, 110-pound woman and it’s easy even for me to fold up and roll into corner of room when not in use. Thanks 3G Cardio!
For the price, I’m really impressed how sturdy the 3G 80i is. Nice size for exercising, but it easily folds up for quick storage.
My home gym is complete thanks to the 3G Cardio Fold Flat Treadmill. I have a small workout room and this treadmill fits in perfectly, leaving enough room for an area to do Yoga.
The 3G Cardio 80i Fold Flat Treadmill is ingenious! I never would have thought something so small could be so sturdy. I watch TV in my living room while walking on it 4-5 times a week, then roll it out of the way when not in use.

Having had this treadmill for several months now, I find I have no complaints about it. Aside from an occasional application of treadmill oil, the treadmill performs flawlessly. While I know I can fold it up I have no need to. I have used it to both fast run and to jog. Now that the pandemic has slowed and I am vaccinated, I have resumed going to the gym however, I still very much use the treadmill. I highly recommend it.

Service above and Beyond. Received the 3G 80i about a month ago and I had a few issues with the treadmill working day in and day out. I worked with John Standridge from the support team. He kept me up to date on our avenues to solve the issues and at the end of the day he made me one super fan of 3G Cardio. Honestly, I was surprised at the level of service and how promptly things went to solve my issues. At the end of the day, I couldn’t be happier with my decision on a treadmill.
Had it for years, wife loves it…
