Overview of the Nordictrack S40
The main features of the Nordictrack S40 are its 3.0 CHP motor, the 12% incline, and the one-touch controls. Unfortunately, the S series is one of the older product ranges of the Nordictrack line up and you might want to look into the C1650 or T7.5 as an alternative.

Have a good look at the market what you can get, but this treadmill might not be an ideal choice for buying something new.
Pros of the Nordictrack S40
- 3.0 CHP motor
- One-touch controls
The 3.0 CHP motor makes this a long-lasting treadmill for someone who runs a lot. Especially used this might be a good steal. The one-touch adjustments for speed are also a great feature of Nordictrack treadmills which make them more user friendly as you only need to push one button to get to the right space.
Cons of the Nordictrack S40
Cons of the S40 are:
- Price
- Age
For the age of this product line, you still pay a pretty high price. This is good for Nordictrack to empty their inventory of old models, but not necessarily for your purse. If you buy new you may want to get for the newer models in the X line or the T line which have followed the C line of Nordictrack models.
Alternatives for the Nordictrack S40
Good alternatives for the S40 are:
The Nordictrack T7,5 is, in my opinion, a better alternative to the S40 unless you manage to get a discount on the S40. The T7.5 is the more modern machine and has almost the same specifications. They also punch in the same budget weight class. So stick with the T7.5 instead of the S40 in the Nordictrack portfolio.
The FS5i is a good alternative for an elliptical for a home gym or commercial gym. It costs roughly the same as the S40 and comes with Free Stride technology. The FreeStride technology puts the flywheel in the middle of the machine. This enables a longer stride and you can also use the elliptical as a treadmill, elliptical, and stepper in one. This freedom comes at the price of a more error-prone design and more challenging movement patterns.
If you want to save some money and like rowing, you can go for the Concept 2 Model D rower. This is the flagship model from Concept 2 who has been around for years in the rowing place. You will be hard-pressed to find a major commercial gym without one of these on the floor. They come in under 1000 and might be a get alternative to consider. The only challenge is that they take up as much space as a treadmill, but are easier to move.
The Rogue Echo Bike is my personal favorite for home gyms as it is compact, sturdy, and burns a lot of calories per minute if used right. This machine can be gotten at the 700 mark and will last for a lifetime. The big disadvantage is that the Echo bike has no onboard entertainment whatsoever. If you need a video or machine to motivate you to get your training in, this is not the one for you. This is a great tool for intrinsically motivated people who want to save money and space.
Summary for the Nordictrack S40
As with the entire S series you might want to opt for something else which is a little more modern and therefore will get more support from the vendor Nordictrack. Always check the US website and compare the portfolio with the Uk website to avoid that you are buying something with is being discontinued. At the time of writing the S series is not available in the US anymore where Nordictrack headquarters is situated.

The C1650 is a good upper range option from Nordictrack for the UK market, especially if you want a bigger touchscreen for your professional or home gym.
Pros of the Nordictrack C1650
The main advantages of this treadmill are:
- 3.5 CHP motor
- 10-inch monitor
This machine is good when you expect a lot of usage by people who want to be entertained while they are running. It is also a better value for money option from Nordictrack as a new buy than the S50 in my opinion. The 3.5 CHP motor gives it longevity while the 10inch touch monitor is an upgrade from most other options.
Cons of the Nordictrack C1650
- No 40% incline
- Relatively high price
The C1650 is still a machine that has quite a high price. If you do not expect to run a lot of miles in each session or expect multiple users per day the motor might be oversized. For the price tag, you will also not get a 40% incline which other models might offer you for the same budget. Here you can see how important it is to make a plan which features you are actually interested in.
Alternatives to the Nordictrack C1650
Some alternatives to the C1650 are:
The Nordictrack X7i is a good alternative for the home gym user who wants a 40% incline at the same price as the C1650. The motor is slightly smaller with 2.75 CHP and it has no touch screen, but in return, you get the 40% incline. So if you are not a marathon runner and preparing for long-distance races, but want to use a treadmill to use weight, the X7i might be a better option as the C1650.
The ACT Commercial 7 is a center drive elliptical which is very compact. If you want to save space in your home and do not like the pounding of a treadmill on your joints, the ACT 7 commercial is an alternative to the C1650 at roughly the same price. Definitely a good option for seniors or less ambitious fitness enthusiasts.
The TrueForm Runner is a self-propelled treadmill that is a great fit for anyone who wants to do starts and stops for sprints on a treadmill. If you are a short distance runner, football player, or any other kind of team sports-related athlete you want to look into this piece of equipment. The TrueForm Runner is hailed in many reviews as the best one of the self-propelled kind. This comes at a price, so be prepared to pay significantly more than for the Nordictrack C1650 for this model.
The Assault air runner is the other option in the self-propelled treadmill market. Compared to the True Form runner it comes in at a lower price. While this is a bonus, the reviews I have seen are slightly worse than for the TrueForm runner. The most common remark is that the bearing mechanics of the belt are calibrated better in the Trueform runner than in the Assault air runner. The Assault air runner seems to be unnaturally fast.
The öast aöternative to the C1650 is the Rogue Echo bike which is my personal favorite for home gyms. It is compact, affordable, and burns a lot of calories without being too hard on the joints. You will not get any multimedia options with it and the display is kept simple. This is the type of 20-minute maximum cardio machine which is ideal for the home. Yes, you can get cheaper bikes, but definitely not built like a tank like this one. With a price of around 700 - 800 it competes with competitor models in the 1200 - 1500 range.
Summary of the Nordictrack C1650
The Nordictrack C1650 is a good machine for anyone who expects to crunch more than 100 miles a week at home or in the gym. The big motor will make it long-lasting and a good buy. If you are not a long-distance runner you might want to look into other options which cost less but still provide a to of different features.
