The 3G Cardio 80i Treadmill has an ingenious design that allows a user to fold the treadmill upright, fold it flat to the floor, and store it under a bed. When folded flat to the floor, the 3G Cardio 80i Treadmill has a shallow height of only 9.75″.
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 all users. With the capability of reaching 11 mph maximum speed and an intense 15% maximum incline, it would be very tough for someone to outwork this treadmill.
The console has eight built-in workout programs, including fat-burning, heart rate, climbing, and interval training. In addition, the display screen displays essential workout readouts like time, distance, speed, calories burned, etc. Furthermore, the console has two water bottle holders and two built-in speakers.
The 3G Cardio 80i also has a soft suspension on the treadmill belt. Therefore, it is ideal for a high-intensity cardio workout so that users can safeguard their joints and muscles. Thanks to its high-quality suspension system, this treadmill has won awards as the softest design for the best running and walking treadmill on the market.

One of the essential qualities that a running treadmill must offer is a heavy frame and deck to supply maximum stability. This particular treadmill model’s assembled weight is 225 lbs (102 kg), which is significant in its stability. On top of that, the rear base rests on cushioned stabilizers, enhancing its stability. The front base rests on a set of wheels, facilitating the assembled machine’s relocation.
The steel frame of this treadmill comes coated with anti-corrosive paint. The very few acrylic parts are the side rails, the motor cover, the dashboard, and the console mast covers.
Compared with the 3G Cardio Elite, the 80i model has a smaller footprint. It’s actually about 10″ shorter, taking only 74″L x 33″W (188 x 84 cm) of floor space. On top of that, it offers a folding design. As its name suggests, it can be folded flat to the floor, with the console masts and the console folding down over the deck. However, the deck can also fold up, like the Horizon T101-05 Folding Treadmill, for example, as it features a folding mechanism based on two pneumatic cylinders.
When folded flat to the floor, the treadmill’s height reaches only 9.75″ (24.7 cm). Thus, you can even store it under the bed if your bed has over 10″ clearance.
Its features and folding design indicate that this treadmill is for home use. Also, this particular aspect makes it an excellent choice for small apartments.
Deck and running surface
The 3G Cardio 80i is one of the few treadmills with a fold-flat design that withstands running. In addition, its deck features sturdy construction, holding users up to 325 lbs (147 kg).
The deck incorporates a suspension system that renders the run much smoother, reducing up to 30 percent of the impact on your joints. In addition, it uses high-grade, precision-crowned rollers with sealed bearings made for lifetime use.
This treadmill uses a multi-ply tread belt, resistant to stretching. It offers a running surface of 58″L x 18.5″W (147 x 47cm), which is a bit small for taller runners. The average running treadmill surface starts at 60″L x 20″W (152.4 x 51 cm).
However, even a 6’4″ (193 cm) runner shouldn’t feel crammed on this treadmill during a running session with a high-speed setting.
80i Motor and incline
The 3G Cardio 80i treadmill comes with a 3.0 HP heavy-duty motor. This motor is powerful enough to support prolonged workouts at the highest speed settings without overheating, even if the user is near the maximum specified weight capacity.
It can supply speeds up to 11 MPH and starts a 0.5 MPH. The speed is adjustable in increments of 0.1, making the transition from one level to another smooth, and you can select the most comfortable pace for you.
This motor is far from being a noisy one. And along with the cushioned deck, which absorbs quite a bit of the cadence sound, this treadmill is a reasonably quiet run.
This treadmill also offers a motorized incline system. The incline ranges between 0% and 15%. Thus, it can provide a maximum slope of approx—11 °. The incline is adjustable in increments of 1%.
Even though the incline supplied by this treadmill isn’t exactly close to the power incline offered by commercial treadmills, it still greatly diversifies the number of possible workouts.
Also, keep in mind that running at 11 MPH, and using the maximum incline setting of 15% on this machine, will offer quite a challenge. With these settings, a non-professional runner shouldn’t last more than a couple of minutes.
Since this treadmill features a series of onboard programs, speed and incline will adjust automatically by using one of them.
This fitness machine requires a standard three-prong outlet on a 110v power circuit, at least 15 amps and 20 amps.
It comes with a power cord with a standard plug, not an adapter. The power cord connects to the motor case near the front base.
The console features a display of approx. 6.5″ diagonal, with integrated blue backlight, offers a better reading even in a darker room. It tracks speed (in MPH), distance (in miles), time, pulse, and calories burned. It also indicates the current speed and incline levels.
The console has eight preset programs, including Warm-Up, Fat Burn, Heart Exercise, Summit Climb, Long Distance Run, Rolling Hills, Speed Interval, and Speed Burst. These will adjust incline and speed automatically, depending on the current segment of each one of them.
Two user profile settings allow you to create and save two distinctive custom workouts. Each custom workout features 16 sections, and you must set up a speed and incline level for each segment.
Also, you can assign a time goal for each custom workout. Finally, just like any other treadmill, this one offers a Manual mode, which allows you to freely adjust the incline and speed as you want during your workout.
Each of the eight preset programs has its key on the console; for the user programs, there is only one key. The incline and speed are adjusted gradually via the UP/DOWN arrow keys.
However, there are also quick keys for incline and speed adjustment: 0,3,6,9,12,15 for incline and 2,4,6,8,9,10 for speed. In addition, the console has a Stop key, which is excellent to have if you want to pause your workout without resetting your data and resume it later. And just like any other treadmill, it features a safe, magnetic key.
One last aspect to mention here reflects the pulse reading capability of the console. The unit can only read pulse via the sensors integrated into the machine’s handlebars. It’s not telemetry enabled. In other words, it cannot read the pulse via a chest strap transmitter.
The console supplied with this running machine isn’t a fancy one. It incorporates only two amenities: its sound system and a bottle/accessory holder. The integrated sound system is compatible with most MP3 players, smartphones, and tablets.
The sound it can render is far better than the average tablet or phone speaker’s music. But like in most fitness machines that feature a sound system, volume adjustments are made only from your device. The console has no volume adjustment keys.
80i Assembly and Maintenance
One of the best parts of the 3G Cardio 80i treadmill is that it doesn’t require any assembly. Instead, it comes fully assembled and folded. So, you only have to unbox it, unfold it, plug it in, and start running.
Maintenance doesn’t require much. But, like any other treadmill, its deck may require lubrication every 3 to 6 months, depending on how often you use it.
It’s advisable that each lubrication use approximately — 30-40 ml of a silicone-based lubricant. Also, vacuuming under the deck and cleaning the tread belt with a damp cloth is necessary, especially if you have pets.

6 thoughts on “3G Cardio 80i Treadmill | Ideal for a High-Intensity Cardio Workouts”
This is an insightful and helpful article. Finding a stable and durable treadmill can be a very tasking job due to the number of products available these days. This 3G cardio 80i treadmill looks so amazing. It has a lot of excellent features, especially the folding up for storage. I would love to own this treadmill. Thumbs up.
This sounds really great, for someone like me who has very limited space at home, I believe this 3G Cardio 80i treadmill will surely do the job for me.
I just love the fact that I can easily fold it and put it away, as easy as that.
It would have been better if the console is telemetric as it would have added more value to it, in my opinion though.
But in all, I believe it’s a great buy.
I was never a runner. I always maintained I was built for comfort, not speed. I also broke my leg when I was young and always used that as an excuse, be it a poor one. Then, in an effort to surprise and please my wife, I bought a second-hand treadmill.
My first run probably wasn’t more than four or five minutes but I stuck at it. Over the course of a year and a replacement ‘running tread,’ I managed to improve my running time to 30 minutes and about an 8 and a half minute mile. I loved it.
I graduated to outdoor running but then injuries took over and I gave it up. Fully healed now, it might the right time to start looking into running again. This 3G Cardio 80i model might be more than I need at present but I do like the soft suspension technology. If I did buy another I think I would need that as an option.
I’m glad to hear that you healed from your injuries and are thinking about running again. I’ve had back and knee injuries so I know what you mean about the soft suspension technology.
A few years ago I learned about the Octane Fitness Zero Runners. This technology makes it seem like you are running on air and they are zero-impact. They are the coolest pieces of exercise equipment I’ve ever seen.
There are 4 models, the ZR7, the ZR8, the ZR7000, and the ZR8000. They are portable so they can be moved inside or out. However, I wouldn’t keep it outdoors for storage. Their cost is expensive but I think they are worth every penny.
I’ve included links above so that you can check them out. Good luck with running again!
This article is excellent and helpful in deciding what is best for you! I like its dual folding technology because lack of space could be a problem! And the shock-absorbing elements are a must-have if you live in a flat and have neighbors, so thumbs up! Last, the 3G Cardio 80i Treadmill caught my attention when I saw that NO assembly is required, so I believe it is a great buy!
Hi Lucy, thanks for stopping by and sharing your thoughts with us. Please let me know if I may further assist you with exercise equipment. I’m always happy to help.
Kind regards, Robert
