NordicTrack T 6.5 S vs T 8.5 S

When it comes to selecting a top-notch treadmill equipped with iFit, the NordicTrack T 6.5 S and T 8.5 S are two models that frequently find themselves in direct competition.
Both the NordicTrack T 6.5 S and the T 8.5 S are popular treadmills with very similar features. We recommend the T 8.5 S because it has a more powerful motor (3.5 HP vs. 2.6 HP), a larger running area, a cooling fan, and a 10-inch HD color touchscreen.

Running Area

When choosing a treadmill consider how you will use the treadmill mostly and the space available in your room. An 18-inch belt is suitable for walking. For runners, we recommend  20 inches or wider.

The length of a belt can vary from 50” to 65”.  55 inches will work for most people but, if you’re taller than 6 feet go longer.

20″ x 55″

20″ x 60″


Foldable treadmills allow you to fold up the machine in seconds and store away to conserve space. Both treadmills are easy to fold up.

Motor Power (HP)

The more power a treadmill motor has the faster it’ll be at changing speeds. We recommended treadmills with a motor of at least 2.5 horsepower or more.


Maximum Weight Capacity (LBS)


Maximum Speed (MPH)

Today there are many entry-level treadmills that reach 12 mph. 10 mph is the minimum speed for running, but we recommend you to get one that can reach 12 mph.

Heart Rate Monitor

Knowing your heart rate during a workout is important for maximum fitness benefits. Today we have many methods to measure our heart rate, but a built-in heart rate monitor has other advantages, like heart rate oriented workout programs.

Heart rate monitoring on the NordicTrack T 6.5 S is facilitated by the Dual CardioGrip™ Heart Rate Monitor. The handrails of the treadmill are fitted with heart rate sensors. A horizontal handrail that extends in front of the console is designed to provide a comfortable grip while reading your heart rate.

Heart rate monitoring on the NordicTrack T 8.5 S is executed via EKG Grip Pulse sensors located on the handlebars. This method provides real-time heart rate readings, allowing you to monitor your cardiovascular performance and stay in the optimal heart rate zone for your specific fitness goals.
