Treadmill Review

Last Updated: June 9, 2023

The Nautilus T614 treadmill is a decent treadmill on its own merits. It can accommodate a user weighing up to 300 lbs, has a 2.75 CHP motor, an incline range of 0-12%, and 22 workout programs. However, it falls into a competitive price range and once it is compared to other competitors’ treadmills, the T614 does not hold up well.


The Nautilus T614 is priced at $949.

The T614 Is Built For Users Who:

  • Are walkers or joggers - The T614 is meant for walkers and joggers, not runners. It is not constructed to withstand regular running use.
  • Prefer well-labeled consoles - While it presents a slightly busy look, the T614 console is easy to use as practically all the buttons are clearly labeled, as well as all the console information.
  • Like flexible decks - The deck on the T614 is fairly springy and flexible, which may appeal to some users over those who prefer a firmer deck.

Why The T614 earned 3.4 stars

There is three main aspect which merited the T614 star rating we gave it.

  • Slightly underpowered motor - Many treadmills in this price range have at least 3.0 CHP motors. The T614 has a 2.75 CHP motor.  
  • Good treadmill construction - The T614 is a well-built, affordable treadmill which is similar in sturdiness to the SOLE F63.
  • Outclassed by competitor treadmills - While the T614 is a decent treadmill, many of its specs fall short of competitors’ treadmills.

At Treadmill Reviews, we do our best to judge a treadmill on its own merits before comparing it to other treadmills in its price range. However, a key part of ranking a treadmill is comparing it to other treadmills that share its price range. As it stands, the T614 falls short of the best treadmills under $1,000.

T614 Review: Build Quality

    • Warranties - 10 years frame and drive motor, 2 years mechanical/electronics, 1-year labor
    • Belt - 2-ply
  • Rollers - 2.5” crowned
  • Cushioning - StrikeZone™
  • Customer Support - Email, phone
  • Return Policy - 6 weeks post-delivery

The warranty period on the T614 is surprisingly short and restrictive. With only 10 years on the frame and drive motor, the T614 treadmill warranty falls far short of competitors’ treadmill warranty.

Refund period runs within the first 6 weeks, with the time period starting from the delivery date. Refunds on the T614 will not include the shipping costs or assembly fees.

Bottom Line Review Of The Nautilus T614 Treadmill

The T614 is a solid treadmill with decent features. However, as we examined it, we noticed specific areas where it fell short of being one of the best treadmills under $1,000.

  • The SOLE F63 has a larger, 3.0 CHP motor and a weight capacity of 325 lbs, out-matching the T614 2.75 CHP motor and 300 lbs capacity.
  • The NordicTrack C990 is equipped with a 7” touchscreen and 32 workout programs, compared to the T614 LCD and 22 workout programs.
  • The ProForm Power 995i has an incline range of 0-15% and a running area of 60” long and 20” wide, compared to the T614 incline range of 0-12% and running area of 55” long and 20” wide.
Overall, we recommend you check out the above treadmills if you are looking for a treadmill in the price range of the T614.
