Marcy Folding Motorized Treadmill jx-663SW Review

The Marcy Folding Motorized Treadmill JX-663SW model is another great home treadmill by Marcy. It is similar to the JX-650W and JX-651BW model as it is still considered a beginner model. It is a little bigger with a bigger running surface but still it isn’t too big or bulky and the folding option offers great storage space for when it’s not in use. Again like the JX-650W and JX-651BW, this machine is not meant for intense workouts, as its running area isn’t very large but should offer a little but for room for taller people. It is great for beginners as the size of this model is the perfect size for walking and jogging but in this model the motor has speeds from 0.5 - 9.0 MPH (instead of 8MPH). You can increase the speed by 0.1 MPH, which again is great for beginners to find their perfect speed! With quick keys for 2,4,6, and 8 MPH. The biggest differences are that in this model you have MP3 aux port, built in speakers, pulse reader, and an incline! This is great for adding difficulty to your workout. This is considered a good step up from JX-650W and JX-651BW models

The incline is motorized and features an incline range between 0%-15% and increase by 1%, which is great for finding a good position for you! Some of the pre-set programs will choose this for you. There are also quick adjustable keys for 2, 8, 12, and 15 for a quicker incline.

The console displays speed, time, distance, calories burned, and pulse that are perfect for beginners but the pulse reader is a nice touch for more experienced people. Every pre-set workout has its own automatic speed but it can still be adjusted if need be and you also have the ability to create your own workout. This is great to help you stay motivated! This model does include a tray for you tablet, phone or TV remote. The MP3 is great addition as the sound from the 2 speakers will be better then you phone speaker and you won’t have any wires dangling from ear buds!

The JX-651BW model has steel frame that can support up to 245lbs and features a corrosion-restraint powder coating that comes in a Gray colour. Is has the 2 sets of shock absorbing cells that will make running easier on your joints!. This model weights 145lbs after it is assembled which is more then the other 2 models so you may want 2 people to move it and assembled it. You get wheels when it is folded up to make moving it around your home a lot easier though!

Measurements for the Marcy Folding Motorized Treadmill JX-663SW

The measurement when assembled is 67” x 30” x 53” (LxWxH) and has a running surface of50” x 17.7” (LxW). Like mentioned above, taller people might have a harder time doing longer strides but it is a little bit bigger which helps.


The warranty for the JX-663-BW model is 2 years.

Final Conclusion for the Marcy Folding Motorized Treadmill JX-663SW

My review on the Marcy JX-663BW treadmill is that it is a little bit of a step up from the JX-650W and JX-651BW models. It’s a great treadmill for beginners but has a few extra features like the incline to add more of a challenge! Plus the MP3 with speakers makes working out more pleasurable. The next thing is that it comes with everything you need, for example: the pre-set workout and ability to create your own workouts, ability to track speed, distance, pulse reader etc, to the 0.1 MPH increase to make sure you find that perfect speed! All of that plus the ability to fold up the machine to save space makes this a perfect way to lose some pounds, tone up and increase your cardio in the comfort of your home!
