NordicTrack S45i treadmill Performance

NordicTrack S45i treadmill has an incredible performance as compared to other machines in its price range. S45i NordicTrack is a performance treadmill that keeps up with most experienced and elite runners.

The 3 CHP motor delivers ample power that drives the treadmill’s running belt to a top speed of 13mph. This maximum speed roughly gives 22kph, indicating that NordicTrack S45i treadmill is pretty fast, enough to burn more calories when sprinting.

Moreover, the commercial 3CHP motor is powerful enough for speed training and endurance runs. You can quickly adjust your speed and incline at a touch of a button instead of scrolling through many options.

You can achieve tremendous calories and fat-burning by adjusting to high speed and high incline with less efforts. With only 1-touch responsive control, you can change your walking or running intensity.


NordicTrack S45i treadmill Reliability

S45i treadmill feels very reliable, stable and balanced when you are exercising on it. Overall, NordicTrack S45i treadmill is built to withstand the longest workout.

With an appropriate user’s weight on the belt, the powerful, noiseless electric motor operates for long and efficiently. The auto breeze cooling fan just makes fittest runners enjoy intense training sessions and long workouts.

Moreover, s45i NordicTrack treadmill comes with a large and sturdy frame. So the machine operates with more stability and balance. Also, the heavy duty or  powerful motor plus the 1.9 inches precision and balanced non-flex rollers reduces vibrations.

Another reliable addition is the treadmill’s weight capacity. The maximum user weight limit on s45i treadmill is almost 300 pounds. That means the fitness equipment is allowed for a wide range of users, an all types of runners with body weight from 1 pound to 250 lbs. Reliability will greatly reduce if a 300-lb person runs on the 300 lbs weight capacity treadmill.

NordicTrack S45i treadmill Conformance

NordicTrack conducted rigorous testing to assure they meet the highest quality standards.


NordicTrack S45i treadmill Durability

You know that NordicTrack has a reputation for making really smart and high-quality gym equipment. S45i treadmill has a 10-year motor warranty, 2 year parts and lifetime steel frame warranty. This protection is the sign of the company trust that their product will last longer.

The NordicTrack S45i treadmill’s self-cooling fan reduces overheating, so it is certain that your treadmill drive system won’t overheat and would remain durable.

The commercial grade treadmill belt is tough enough to allow you stretch your steps or strides as you want. But it is only a 1-ply walking belt, not 2-ply.

Overall NordicTrack S45i treadmill looks rock solid, according to many customer’s reviews and is too heavy. You know, electronic components don’t last longer as the steel frames and motor, right?


NordicTrack S45i treadmill Serviceability

Does this NordicTrack S45i treadmill need to be serviced? All treadmills require periodic maintenance, belt lubrication to reduce wear and tear. So, you have to stick to regular maintenance for your S45i treadmill.

If the warranty is still valid, and your NordicTrack S45i treadmill is broken, you can take it for NordicTrack treadmill repair and equipment services. You also have to call NordicTrack to replace a part.

NordicTrack S45i treadmill Aesthetics/comfort

NordicTrack s45i treadmill has a commercial gym quality feel and look.

it operates quietly (no loud noise), has a sleek attractive TV screen, Onetouch™ Controls, smooth running motor and a Auto breeze Fan . The machine also comes with a folding SpaceSaver design meaning you can store and run it in smaller apartments and rooms with small spaces.

The console is a nice size full color capacity monitor, and a touchscreen TV. It feels cinematic watching your streaming movies from it, while working out. Again, the screen’s wide viewing angle makes it pretty easier to glance and read feedback and workout stats.

Moreover, if you suffer bad knees and painful hips, the cushioned deck reduces impact of every step you make. The 51 x 140 cm tread belt will endure any type of training you need while giving you a comfortable natural run.


NordicTrack S45i treadmill Safety

You can walk, jog or sprint on this treadmill with little impact on your ankles, hips or knees. The Safety key is a greater part of the overall treadmills ability to safety operate. If it gets missing, a universal safety key is available for all NordicTrack treadmills.

But of you are desperate to work, how do you get your treadmill to work without the safety key? Making your NordicTrack S45i treadmill run without the safety key is possible if you install a jumper bypass at the safety switch.

The NordicTrack S45i treadmill does not recommend it though, because operating the treadmill without the safety feature may lead to potential accidents. If you want it, check how to make treadmill run without a safety key.

I prefer you replace the safety key if the original one goes missing. But some NordicTrack have manual modes, unfortunately, NordicTrack S45i treadmill has no manual mode.
