Motor and Speed:
The NordicTrack T 6.5 Si features a 2.6 CHP DurX™ Commercial Plus motor, providing smooth and quiet performance. During my runs on the 6.5 Si, I found the motor capable of handling my daily workouts, reaching speeds of up to 10 mph with ease. This model is ideal for walkers, joggers, and occasional runners.
In contrast, the NordicTrack T 8.5 S boasts a powerful 3.5 CHP DurX™ Commercial Plus motor. When I tested the T 8.5 S, I was impressed by the motor’s ability to handle more intense running sessions, it can reach a top speed of 12 mph. The T 8.5 S is suitable for more serious runners or those looking for a more powerful treadmill for their home gym.
Incline and Cushioning:
One of the features I enjoyed about the NordicTrack T 6.5 Si is its 0-10% incline range, allowing me to add variety to my workouts and target different muscle groups. Moreover, the treadmill’s FlexSelect™ cushioning provided a comfortable running surface that eased the impact on my joints.
On the other hand, the NordicTrack T 8.5 S offers an impressive 0-12% incline range, providing even more options for workout intensity and variety. While running on the T 8.5 S, I appreciated the same FlexSelect™ cushioning that reduced joint stress, making for a more comfortable experience.
Display and Workout Programs:
The NordicTrack T 6.5 Si comes with a 10-inch HD touchscreen display, which I found engaging and visually appealing. With 20 built-in workout programs and access to iFit, I never ran out of workout options and enjoyed the interactive training sessions with personal trainers.
The NordicTrack T 8.5 S, however, steps it up with a larger 14-inch HD touchscreen display. During my time on the T 8.5 S, I found the larger screen more immersive, especially when using iFit’s virtual training sessions. The T 8.5 S also comes with 50 built-in workout programs, giving users a wider range of options to choose from.
Price and Value:
The NordicTrack T 6.5 Si is generally more budget-friendly compared to the T 8.5 S, making it a suitable option for those looking for an affordable yet reliable treadmill. However, if you’re willing to invest more for a powerful motor, increased incline range, and a larger touchscreen, the NordicTrack T 8.5 S might be the right choice for you.
What Customers Say About NordicTrack T 6.5 Si
People generally seem to have positive opinions about the NordicTrack T 6.5 Si treadmill. Many users praised the treadmill for its overall quality, sturdiness, and good shock absorption, which provided a comfortable experience during workouts. They also appreciated the built-in screen and speakers, as well as the one-year iFit membership, which allowed them to track their progress and enjoy personalized workouts.
However, some users pointed out that assembling the treadmill could be challenging, often requiring two people and taking between one to two and a half hours to complete. A few users reported issues with the heart rate sensors and a slight lean on the treadmill, which made folding it up difficult. Moreover, some customers experienced delivery issues and had to reschedule their delivery dates.
Despite these concerns, the NordicTrack T 6.5 Si treadmill appears to be a solid option for home use, providing a reliable and comfortable workout experience.
What Customers Say About NordicTrack T 8.5 S
Customers generally seem to be satisfied with the NordicTrack T 8.5 S treadmill. They appreciate its sturdiness and the fact that it can be easily folded to save space. The iFit feature is a popular aspect, as it offers guided runs and virtual “travel” experiences that make workouts more enjoyable. Some users have found the assembly process a bit challenging, but overall manageable with the help of another person. The treadmill’s cushioning is praised for its comfort during running.
However, there are a few downsides mentioned by customers. Some users have experienced issues with the heart rate monitor and the safety key, while others have found the touchscreen slow to boot up. Additionally, there is disappointment regarding the lack of headphone connectivity for audio, which can make it difficult to hear the iFit audio during workouts. Despite these minor drawbacks, most customers seem to be happy with their purchase and feel the treadmill offers good value for the price.
Conclusion:
In summary, both the NordicTrack T 6.5 Si and T 8.5 S are excellent treadmills. The T 6.5 Si offers a great balance of features at a more affordable price, while the T 8.5 S provides enhanced performance and advanced features for a higher investment and it is a bettr option for runners because of its 12 mph top speed.
