If you're looking for a treadmill that delivers a solid cardio experience without taking up too much space, this model certainly fits the bill.
I've used plenty of treadmills in gyms, and this is no where near the tech or heft of a gym treadmill but unless you're running on it 10 hours a day, it doesn't need to be. And it's very VERY easy to move. However, be careful assembling it and moving it because the base lifts and you can really pinch your hand if you're not careful. This is not unique to this item, all treadmills are like this. It was very easy to assemble. I did it alone and it took less than half an hour.
I use it before weights for 10-20 minutes and after weights for 20 or so minutes, and for 45 minutes on off days. It's been working perfectly well for 4 months. The emergency stop worked when I accidentally pulled it so that's good news. It doesn't seem like a running treadmill, I only use it for walking. I think it CAN get fast enough for running but it is way too close to the ground. There isn't enough clearance to be comfortable running or running hard on the deck. I have it on carpet with a medium height pile and I've had to place a mat under the machine so it doesn't rub the carpet when I'm on it (and I'm not unusually heavy or anything). It was an easy solution but keep it in mind when placing it.
It did smell the first one or two uses but it went away. No one uses it but me and I use it 6 days a week and it's been working perfectly, no issues 4 months in, and it has
been wonderful to have available in the home. Makes getting a little fitness in so much easier than going to the gym.
My other dilemma was, what if I get it and it just sits there? What if I waste money… on a whim? Well, this was really no whim. Bottom line was that I truly needed something to help me exercise. It’s a necessity.
I need to exercise! I have to, no choice!
Then I worried about assembly. Ug! Would this treadmill take a genius mind to put it together? I knew I could eventually figure it out but I just didn’t want the headache. I fretted over that quite a bit. I read a review that said it was simple and nearly put together already, but you know, I didn’t quite believe it.
It all came back to, I need to exercise and I don’t belong to a gym. Gyms, for me, are just too crowded and I don’t want to get dressed up to go. Sone might be able to go looking like a hag but I can’t. I don’t want the pressure of seeing all the muscle bound people. Sorry, I truly admire them but am not one of them.
Ok, so, I got this treadmill last week. It came! When I opened the box it was pretty much put together. Wow. A few screws and it was ready to go. It works. I was so happy and relieved about that.
Is it loud? NO! The main noise I hear is my feet hitting the tread as I walk. The machine itself is exceptionally quiet.
Oh, another thing I worried about was the width and length. I’d read reviews and felt concern over that. Would it be ok, for “me”? I’m 5’8”. Well, I’m no runner, so for me? Perfect! I can walk as fast as I want without any problem. I don’t run anyway, as I don’t like that for my joints. I’m truly not sure if I could run on it or not. I lean towards not though.
Another advantage? It takes up such a small space and is not intrusive in our family room. Plus it folds up and yes, gently unfolds.
So all in all. I am VERY HAPPY! I’d recommend this treadmill to anyone.
Wanted to try this thing out a bit before reviewing but it has not disappointed. It was easy to assemble and not too heavy. It folds up and down like a dream (see video). It’s true it’s not the same heavy duty treadmill you’ll find in a gym but we weren’t looking for that. It’s quite small when folded and easy to move around (it has wheels). We thought we’d store it in the garage when not in use but it turns out it’s small enough we’ve been able to leave it in a corner of the living room. I will say that when my husband uses it- who is much larger/more muscular than me and works out harder than I do- you can kind of see where it’s limits would be as far as what it can take. That said, it’s held up nicely for both of us. If you’re planning to practice for a marathon and straight up run on it for hours and hours, it might not have what you need. But for us, who just want something affordable that we can both use at home, with our differing workout levels, that will fit in the house nicely and be easy to maneuver, this is a stellar machine for the price and exactly what we were hoping for. Happy with this purchase and looking forward to using it for quite some time.
An Amazon rep tried to help by suggesting other compact treadmills, but none of them fulfilled all the things I needed/wanted in a small electric treadmill as this one did. While amazon customer service rep could find ones that had the pneumatic kickstand fold down which I definitely required as being a senior I wasn't going to be risking my back by lowering regularly a treadmill, as having had a few treadmills over the years, I knew just what that weight could mean, and being in a super small space, I can only have a treadmill if I can fold it away each time.
However, Amazon could not find me a treadmill with the kickstand fold-down that also came with the important requirement for me of not more than 1.5 hp, which this one beat at 1.0 hp, unbelievably, but true! So such a low 1hp meant I could peacefully walk/jog away and without a single worry any higher usage could plunge me in the dark while on an electric belt as can and have heaters of 1500 watts. So that genuine feature alone was gold. Not only, knowing Pyle products, having had more than one, I knew the quality would sure beat any foreign import, even if it would be imported, so that alone put this above all the chinese contenders that appeared great, but the reviews would show big problems if one had any problems, but Pyle has good customer service, and any problems would get resolved, warranties would be real, etc.
In addition, after having read a zillion reviews on the huge drawback of remote-controlled only treadmills, I was convinced I wanted none of those as too many persons reported when the remotes failed to work, so went in the garbage their money spent on the treadmills. I had no desire to pay a few hundred dollars for an awkward 57lb paper weight to big to actually use on paper so it would become this elephant in the closet. So at that point of my search I had definitely x-ed off remote control only treadmills, and only wanted the reliability I had come to experience of wired console controls, and to my surprise this little treadmill came with a console just like a full-sized treadmill, even if the cup spaces weren't exactly practical, but they still could fit slender bottles and disposable cups, not to mention creative do-hickies. And that was another hard one for the diligent amazon rep to locate.
So I just took the risk ordering it without professional installation, praying, literally, it would arrive ok and not require a return. I was a little shocked though what did come, as for a device this heavy I expected a solid box, but instead the treadmill came in a cut-up box with the sections held together by ordinary packing tape. I can say this is where the praying part did me good, as despite the box was falling apart because the tape was no longer adhering in many places, not a single piece ended up missing or visibly damaged, so here God gets the credit - I am talking loose open sections, pieces scattered, yet everything ended up somewhere in the box. And maybe it could even have been the treadmill I ordered first, who knows, because that packaging was unreal, maybe even it could have been a return, don't know, but since everything, despite the horrible piecemeal packaging, was there, that was good enough, because when you are dealing with heavy items getting shipped, getting any unharmed and complete is a lottery win.
Now having read a lot of reviews of people complaining of getting consoles too big, or if okay, having to get 1 or more persons to help, it led me to do research, which led me to the Pyle's website, pyleusa dot com, and get to see an assembly video there which I saved for when I got mine, and also see an all-important little tip they gave in the answer section, advising to loosen the bottom screws of the arms before trying to put on the console. This tip takes away all the struggles so a senior woman as myself easily was able to put on the console which I could see to some might appear as the wrong size, but instead is the right size, purposefully built wider in order to add tension to stabilize the frame and arms. So loosening the bottom screw on each of the arms so that the arms could wiggle wide, let me easily spread the 2nd arm wide to meet the broader width of the console, and I could only wonder how many returns Pyle had to deal with from customers who thought their consoles were too wide, struggling to pull far enough tight arms made to act like steadying clamps and believing their stiffness was due to the wrong-sized console?
So having those instructions in place ahead of time, made it easy for me to put it together alone, handling one piece at a time.
This treadmill operates at a sweet 1hp while delivering higher speeds than a majority of the digital under-desk treadmills I was looking at, in truth, because many of those under-desks were touting up to 4mph, but users were reporting poor performance at those 'walking' speed only. But having gotten products from Pyle before and knowing the quality, I was certain when this treadmill claimed actually jogging speeds, that the 7mph was actually true, especially combining that the max weight of 265 lbs was 45lb higher limit than the majority of compact treadmills I had been checking out, which supported the claim of having a practical upper limit of 6MPH. And now after having it for a few weeks, I have found the claims of offering higher speeds to be true.
Operating the thing is so like a full-sized treadmill. First you press the start while straddling the metal sides to the running belt; and you get a countdown on the display that then lets you know when you can get on it. Now the more you weigh, the higher start up speed you want to get it after the built-in countdown, before you step on it, or your weight can slow down the belt at the lower speeds, which are truly really lower so that if you are the kind of person not steady, you will be pleased you can start out very slow until you warm up and can put speeds up to normal. As long as you are aware of the limits to a small treadmill as this, you will not be disappointed. If you expect to get the abuse-durability of a $1500 treadmill, you will have reasons to complain, but they won't be based on reasonableness, but expectations too high. I can feel the wood base give sometimes as I walk at lower speeds, but that 'bounce' goes away at smoother higher speed; however, I use that feedback to know the board has limits and if I pound on it too hard, I may break it, all my fault expecting an economic board to operate like one of my former gym-level treadmills.
Having just before this a manual compact treadmill (ProGear), I was already acclimated to the compact running belt size, and interestinly enough, although the progear is around 3 inches longer, for some reason, the electric power of the Serene makes it seem longer and wider, and I had zilch problems walking/running on it, though narrow, it is wide enough and long enough, but I am a smaller person in leg length so a 5'10 plus person might not find it long enough.
Every time I get on it I am glad I one lacking a remote control as it gives me peace if my neighbors start flipping channels on their TVs that I suddenly won't find my running belt jarred to a halt while I am thrust to the floor, which some persons have complained about the digital ones - not attributing the sudden stops to anyone working a remote in another location, but in fact that is indeed a probable cause why their remote-operated treadmills can be unexpectedly halting at dangerous speeds, another reason why I would reject any remote-operated treadmill as they may be sharing frequencies of nearby users of other remotes!
The bluetooth features I also have no interest in, as I am on it to walk or jog, and if I want to be entertained I have it before my computer or I listen to audio, as tiny smartphone / tablet screens are the last things I want to be squinting at as I exercise as reality to me is not played out on the limits of 5-inch x 3-inch screens. To me a treadmill is a substitute when I can't exercise outside, and when I exercise outside it is about movement and not diddling with software apps.
And another thing I wish could be changed is the arm lengths, as I wished the parts where the heart rate sensor were could be folded down, out of the way, at will as once I am steady on it, I like to walk/jog without holding on, making use of hand weights or urban poles on either side of the floor. But the arms are permanently out; however, I may yet remove the sensor holders as I get more practiced.
In addition, the next con could be fixed if I wanted to struggle, but I don't, is the base of the running belt I found to be off-centered, favoring the right so that at first I thought the pneumatic drop-down was defective, but it turned out that wasn't the issue, the pneumatic was reliable, what was happening is that the running belt bed was catching on the side of the arm it was smack against that I hadn't noticed was off-centered until I sought to solve the issue, if possible. Once I understood that, I loved this 'flaw' as I saw that all I had to do was just pull slightly to side the arm it was against when I was ready, and the running bed gently drops to the floor as advertised, the last few inches, really slow so that I have lots of time to position 2 floor raisers when I want to walk on a level surface, instead of the slight incline it has.
And as far as the incline, it is much more user-friendly than the steep incline of my manual ProGear treadmill which was entirely unpractical so I would have to put a couple of heavy boards under to use. So having come from that similar kind of compact treadmill, I have found this Serenity in every way superior, including it to be superior to walk/jog on the electric, as the electric in every way is equal to the features of electric versus manual, as I found the manual too-user intensive, requiring too much effort to let one get into simulated walking videos, and also to be very noisy and requiring hanging on in order to move physically the running belt. The only good thing about the manual, is if the power goes out, but there are so many issues when the power goes out that generally jogging indoors is furthest from the mind.
So if you understand the limits, and your needs require such limits - space constraints, power usage, reliability at budget costs - to me this is the top contender with a trusted manufacturer who does not shrink back when things may go wrong, doesn't cut off communications, and offers buyer-friendly methods to purchase, as I, myself, took advantage of installment payments. I also believe if you don't understand the limits, and expect gym-level quality, you will be unhappy, you will find it cheesy, and it is not noiseless, it the standard treadmill sounds, however, using a mat can help reduce that, but I, myself, go matless because the mat would hog space I don't want to give.
Ok, I'm going to go with a pros and cons list for this treadmill. My pros list is much longer than my cons, this is overall an excellent product and you really can't beat the price.
Pros-
-It folds up nicely and there is a little kick release under the platform that you kick and the treadmill unfolds. No wrestling the treadmill to fold and unfold. I can fold it up with 1 hand by lifting the platform and it locks itself into place.
-It does not take up too much space when it is folded up.
-It is pretty easy to wheel around to where you want it, it isn't too heavy.
-It does the job! It goes from .5 mph (basically barely moving your feet) to 6 mph. It has a bunch of pre-programmed workouts that range from slow to kick-your-butt fast. It also lets you choose your own speed and will run for up to an hour before shutting off.
-Keeps track of how long you've been on, and how far you've gone. It also tells you calories burnt and heart rate, although I'm not sure how accurate those numbers are (I wear a Fitbit, and my heart rate on the Fitbit and treadmill are usually not the same. It also doesn't know how much you weigh, which I think would play a part in how many calories you are burning. It's a lot more effort to move 200 lbs at 5mph for 10 minutes than it is to move 110 lbs, so I think you'd burn more calories the heavier you are. Maybe I'm wrong, that's just my guess...)
- The best PRO is this- If you use it, it works! I've lost 18 lbs and counting since buying this treadmill!
Cons-
-There is no pause button, only Start and Stop. If you need to stop for a second, you have to hit Stop and then start again, but your distance and time will restart.
-The handles or arms of the treadmill are slightly narrow- I want my Fitbit to count all those steps so I like to swing my arms like I'm walking normally, and oftentimes I will hit my wrist into the arm of the treadmill because they are narrow. This is GREAT for storage and the treadmill taking up as little space as possible, it is just a slight annoyance.
-Lubricating the treadmill was a slight pain. I kept putting too little and the belt would lag. I finally ordered a big bottle of treadmill lubricant and lubed the heck out of this sucker and now it works great.
-It only goes up to 6 mph, some of the fancier, more expensive ones go up to 10 mph so if you're looking to RUN, it may be a little slower than you'd like. But 6 mph is plenty for me so this is more of a "maybe a con for YOU, Jacky Joyner-Kersee. I'mma be over here sweating my a$$ off at 6 mph"
So to sum up, if you're insane and still reading my novel on the pros and cons of buying this treadmill, I love it. I recommend it. I'm so happy I bought this treadmill and you will be too!
