Octane Zero Runner ZR8 Elliptical Overview

“RUN SMARTER” that’s the motto of the Octane Zero Runner zr8.  What makes the Octane Zero Runner ZR8 better from the previous version (zr7) are the durable aircraft-grade aluminum legs and lightweight pedals which allows for a faster cadence. On ZR8 model, they also added an extra set of grips for more variety and better performance.

Octane Zero Runner ZR8 elliptical is also self-powered and provides a cordless quiet operation. The ZR8 requires 4 AA batteries for console operation which can easily be replaced. Further design features include the narrow pedal spacing 1.4″ and a low step-up height of 5.2″. Compared to the ZR7 the spacing between the pedals is 0.6″ narrower which allows the hips and lower body to be aligned.

According to Octan Fitness they also improved the resistance range however, we weren’t able to locate the watts of the resistance the ZR8 offers. Octane Zero Runner 8 offers 3 sets of hand-grips, static with the built-in pulse sensors, moving and the performance grips.

Here is the deal with Octane zr8:

You should go for Octane Zero Runner zr8 elliptical if?

  • You are a runner. Octane zr8 is an excellent machine to replace your daily outside running session. Running is a great exercise but it comes with a price of high-impact on the body. Every-time you lift your feet off the ground and hit it back it’s an impact on joints. The Octane Fitness ZR8 offers the all the benefits of running with ZERO impact. With that being said, you can still do your running outside, just wouldn’t need to do it on a daily bases.
  • You want unlimited stride length motion. Octane Fitness Zero Runner zr8 allows you to stretch your legs from ZERO up-to 58 inches. This allows you to target different muscle groups.
  • You are an individual with kneecap issues or joint issues in general. You can now run without impact, and that’s what makes the Octane Fitness Zero Runner 8 a unique cardio equipment. Unlike traditional elliptical machines, ZR8 adopts your motion. Patented hip and knee joints offer a real running experience (without the running impact).
  • You are taller or shorter than average. The ergonomic design and 58″ stride of the Octane ZR8 elliptical allow the user with all sizes to exercise without any difficulty.

  • You have a hard time adapting to new things. The motion on Octane Zero Runner zr8 will feel weird for a while until you get used to it. It’s nothing like your traditional elliptical machine, the movement is different as well as the exercise.  If you want a good quality traditional elliptical, check out Sole E35.
  • You are looking for an elliptical to mimic hill/climbing and strength training. On an elliptical with incline ramp and high resistance level, you can do both cardio and strength training. However, with Zero Runner zr8, you can only do cardio. ZR8 doesn’t have the incline ramp functionality and it also doesn’t provide a powerful resistance. Octane Zero Runner ZR8 offers a substitute for outdoor running for those who want less impact. Therefore, the resistance is not much, in fact, the resistance is not even mentioned on the ZR8.
  • The large touchscreen rich in color LCD display, speaker, and the cooling fan is a factor for you. Zero Runner ZR8 elliptical has a non-backlit display that allows you to track basic information.

Octane ZR8 Review


ZR8 has adjustable resistance built in at the back of the machine. Not in a very convenient location but reachable. However, to adjust the resistance you need to stop the movement. You can set the machine resistance to free movement or increase the resistance to replicate higher intensity or uphill running.

Compared to ZR7 the resistance is improved on the zr8 however, compared to ZR8000, the Octane ZR8 lacks few features and one of them is the resistance level. If you are into doing more intense training, I recommend you to go for ZR8000 because it has more resistance and functionalities.

Stride and incline

Adjustable from 0 t0 58-inch stride length. On most elliptical machines your stride is fixed from 20-25 inches however on the ZR8 elliptical you can stretch your stride to 58 inches. It allows you to run and jog while working on shoulder and arms.

ZR8 features the dual stride trace technology, you can view the health and consistency of your stride movement on the screen. This functionality allows you to easily identify the areas of fatigue. However, while running on the treadmill or outside you can’t trace each stride/step. The downside is that the Octane Fitness Zero Runner zr8 doesn’t have incline ramp for hill climbing.


The display is not blue back-lit but the LCD is clear enough to see the data shown, even in the darker room. On the display, you can track the necessary workout data such as time, speed, calories HR and pedal motion. Octane Fitness Zero Runner offers a basic display and doesn’t have any flashy feature.

Bluetooth and App connectivity
One of the great features of the ZR8 elliptical is the Bluetooth 4.0 and ANT+. It has the ability to connect to the Smart-Link App as well as Garmin Connect IQ App. This means you can connect your Andriod, iPad, iPhone etc with ZR8.

You can download the free Apps connect the machine to your device, create an account put in your info and track your workout data. You can make customize training programs based on your goals. The exerciser can also download workouts plans using the Smart-Link App and add some strength training to your cardio.

What’s really special about the Smart-Link is that it allows you to monitor your stride data in real time on your device’ screen. You can basically see which legs are stretching more or less and performance efficiency and difference aspects of your run. It’s something you can’t monitor on treadmills or outside. The orange rack on the top of the display is where you can put your devices.

The zr8 elliptical machine has 35 built-in programs from endurance to recovery to toning options. It’s more than what many machines offer on the market.

The Octane ZR8 trainer programs include 13 endurance programs, 12 tone up programs, and 10 active recovery programs. However, only 4 of these programs are on the console and the rest of the programs are on Smart-Link App.

Heart Rate
ZR8 also has a heart rate monitor that’s compatible with the wireless ANT+, and Bluetooth 4.0 chest strap for accurate readings. You can either wear the polar or hold your hands on the stationary handlebars to see the HR on the screen. The heart rate chest strap is also included

Media Rack
The ZR8 offers plenty of space on the console for the rider to place their device and stream through their favorite music or monitor their progress on their device.

Handlebars and pedals

Static handlebars, moving handlebars and the performance grips (3 hand-grips options). The ZR8 offers multiple handlebars for the exerciser to change grips and engage different body parts. The moving handlebars allow the user to workout upper and lower body while the stationary handlebars allow the user to concentrate more on the lower body.

There are also performance grip bands which allow you to actually train your core while doing cardio. You can also use them to activate more you get and elevate your heart rate. More importantly, it allows you to find that natural stride for your upper body. It also improves the balance. And the performance grip feature allows users to focus on additional core stability.

The ZR8 comes with large and comfortable Rubber non-slip pedals and toe cage for safety. Regardless of your speed on Octane ZR8 your feet will always stay firm and in place. The pedal spacing is 1.4″  and step up height is 5.2″.

Final Word on Octane Zero Runner ZR8 Elliptical

The innovative design of the Octane zero runner zr8 elliptical allows the user to bend their knee, just like running on the road because the machine has knees and hips that bend. While doing the short strides you can walk and with the long stride mimic running or do sprints.

Smart link app tells your stride length and the height of your heel kick and that way you can easily identify which areas you need to work on more. which is what makes this app smarter than most fitness apps. It also allows you to run and track your states from your device while watching your favorite Netflix show, all at the same time

We believe RZ8 is one of the best elliptical machines on the market. It offers so much for the price.  You pay less than $3500 for something that is both an elliptical and treadmill, except it’s much smarter and healthier. You don’t even need to plug in the machine as it generates the power it needs. So, you can place it wherever you want in the gym or at home and save on the electricity bill.

Run faster, more efficiently and avoid injuries that come with the impact of running. The suspension design allows the exercisers to enjoy the excitement of running without the impact of running outdoors or on a treadmill.
