3G Cardio 80i Fold Flat Treadmill Review

by Jack on May 10, 2016

At the time of  writing (early 2016) this review the 3G Cardio 80i Fold Flat Treadmill could be considered a fairly new model. Having both a powerful 3.0 CHP motor and a spacious 60 inch long running platform makes it a model designed for runners.

Overall, we would rate the overall quality and performance of this model as being similar to the following (see a comparison) models:

In our reviews we concentrate on the 5 most important areas to judge before buying a model. We usually don’t focus on the “extras or accessories” but there is one we do want to mention before getting into the guts of this review. Pictured below will show you the feature we are referring to

3G Cardio 80i Treadmill is flat folding and cen be stored under the bed

Space Saving, more storage options

As you can see in the picture the 3G Cardio 80i treadmill is flat folding which most treadmills are not and this provides more flexible storage options for someone who may be short on space. For example, in the picture above folded down like this the height is 9.5 inches and should be able to be rolled underneath most beds for storage.

The 5 most important areas?

We think when judging which model is best to buy for the amount of money you want to spend the first areas you need to understand are:

  • Motor
  • Frame
  • Tread belt
  • Cushion System
  • Warranty
3G Cardio 80i Fold Flat Treadmill review for runners

Judging the Quality

Area #1 – Motor

When buying a home treadmill, especially if you plan to use it for running there are two main characteristics of the motor you will want to understand: Style and amount of horsepower.

When looking at different models, there are a few different styles of motors you might come across. There is only one style we recommend, the Continuous Duty Horsepower (CHP) motor.

The CHP is by far the most durable and efficient style of motor. Other styles may be acceptable when buying a cheap treadmill but we highly recommend the CHP motor when spending a significant amount of money. This 3G model does have a CHP.

As for horsepower rating. If you are a walker or jogger this is not as important but for runners the lowest horsepower we recommend is 2.5. This 3G model has a 3.0 horsepower motor making it a good choice for running.

Area #2: Frame

Not the most exciting area to talk about but you will also want to buy a quality frame. For the most part treadmill frames are made from either either steel or aluminum.

Out of these two options we recommend steel. This material tends to fit together much tighter making it much quieter when in use compared to aluminum frames. Also, opinion after opinion says aluminum frames provide more of a dead feeling while steel puts a little bounce in your step.

The models frame is manufactured from steel and provides a whopping 350 pound user weight capacity.


Area #3 – Tread Belt 

We don’t rate this as important as the motor or frame but still there are important characteristics: ply (thickness) and dimensions.

Obviously thicker belts will last longer. With that said, even with thinner belts replacement because of wear-n-tear shouldn’t be occurring every month or even every year. If someone were having to replace a belt every month we would either think there was something wrong with the installation or they are getting one hell of a work-out.

The belt thickness of the 3G Cardio 80i Fold Flat Treadmill is very much comparable to other top models in its price range.

What to know about dimensions. This is probably most important for people buying a home treadmill for running. When we are asked whether or not a certain model will work for running, besides the motor and frame one of the first things we look at are the dimensions of the tread belt, primarily the length of the belt.

The average person will need at minimum a belt 55-inches long. We have a hard time recommending any model with a belt shorter than 55-inches

This 3G treadmill has a belt, right about 60 inches long so yes this will work for most any runner.


Area #4 – Cushion System

If we were asked to name the model at a certain price point having the absolute best cushion system this would be a very hard question for us to answer.

We have exercised on and compared 100’s of different treadmills. We have asked 100’s of different people there preference on which model is most comfortable. Of course it is very obvious and easy to feel the difference between a $500 and a $1500 model but when comparing more evenly matched models, rarely is there a 100% consensus on which is the more comfortable.

We believe this is because, as individuals, our body mechanics when walking or running vary from individual to individual. So one treadmill’s cushion system may fell slightly more comfortable to person A. While person B may feel more comfort on a different model.

Overall though, when comparing similar quality and priced treadmill differences are rarely hugely significant. So, while we will not give the 3G Cardio 80i Treadmill the award for #1 Cushion System we will say it rates well against other models at this price point.


Area #5 – Warranty

The warranty could easily be the most important thing you need to look at before spending $1000+ on any model. Maybe we should have put it at the top of the page. We can not stress enough to look at the warranty before buying.

At this model’s price range you should be getting a lifetime warranty on both the motor and frame. This 3G flat folding model does provide a lifetime guarantee on both the motor and frame and also a 5 year on parts and 1 year on home labor. 

Really how good – 3G Cardio 80i Fold Flat Treadmill

Is this the best buy at the price point? See it compared to other similarly priced models. If you didn’t click that link to see how it compares. We will say here, our opinion, it’s not the absolute best for the money but it does compare well.

But with that said, it provides the unique feature of being able to fold flat and rolled under the bed for storage while also providing a powerful motor and platform length for running. We can understand why this would be the best choice for some people.
