TRX3500

This is a great treadmill! We wanted one that is quiet and had an extra long running surface. This is it! Easy to put together, though it takes two people. It’s very solid and well made. The controls are super convenient and work well. The only surprise was that it has only an 8 mm hole to plug something in to the built-in speaker. We had to order an 8 mm to USB C wire for our phones but then the sound wasn’t great anyway. Better to just use an external speaker. All in all, it’s great!

I’m a “runner” (in comparison to a jogger or ‘recreational’ runner) & conducted weeks of in-depth product reviews on Amazon & YouTube of various treadmills. The point of this review is to share what I learned along with why I chose the XTERRA TRX4500. 1st of all, my budget was up to $1,000 and looking for the best treadmill I can find with the needed features and preferences to meet my need as a runner. If I could have found that at $500 then even better...but coincidentally various treadmill options fell in the $1k+ range. My Required Features: *Horsepower - & Why It Matters: You will see models with an HP from 2.0 - 4.5. The TRX4500 HP is 3.25 & the next lower model (XTERRA3500) has a 3.0 HP. If you are a runner, I recommend not buying a treadmill with less than 3.0 HP. You don’t want to be maxing out the motor speed on a regular basis and believe 3.0 & higher will reduce the wear & tear and strain on your motor as a runner. *Overall Size: The TRX4500 has a length of 60 & width of 20 (60x20). After HP, this was the second most important factor as a runner because I reviewed so many models that many looked very small and limited actual running space. As a runner I don’t want to feel constricted with a small physical platform and the 60x20 is perfect. I could perhaps live with a 55x20 but when I’m sprinting and have to slow the machine down to catch my breath, I find myself using every bit of the 60 length. If ur a walker or jogger then a smaller physical platform is fine. As a runner, I could not buy a treadmill with less than 20 inches in width. *Handle Bar Controls As a runner, having speed controls on the side panel (i.e. handlebars) is not just a nice feature but a needed feature. When I’m pushing myself, it’s difficult to rely on reaching the controls on the main panel. It was interesting that other comparative models did not include this feature. *Pace Monitor As a runner, being able to monitor my pace is very important to me and the vast majority of comparative models did not have a “Pace” feature in their metrics. Speed, time, calories & distance are universal but pace is just as important. *Panel Size & Layout In most treadmills, the panel size & quality is actually a significant amount of the cost. The 7.5 Panel size was larger than many comparative models and very pleased with the overall quality (look and feel) of the panel layout. *Speed & Incline The TRX4500 goes up to 12 mph & an incline of 15 degrees. Getting myself back in running shape but I haven’t been able to even touch the 12 mph or 15 incline yet. I’m running at a comfortable 6.5 & sprinting at 8 right now starting out so plenty of ability to improve. Bonus Features: *Quiet Motor I’m a bit of a skeptic when I hear marketing pitches - especially when it’s on just about every comparative model but when XTERRA said the TRX4500 has a quiet motor - it has a very quiet motor. *Easy To Assemble I’m not a handy man kinda guy and if I had my choice, I would have paid for the assembly just for the convenience but with that said, from the unboxing to be able to use - it took about 40 minutes to put together - and it was fairly simple & straightforward. The directions seemed to misname the type of screws but pretty logical which screw fit in what hole so not really a big deal. It was pretty simple and was skeptical something may go wrong but when we turned it on, it powered right up. *Chest Strap Heart Rate Sensor It actually took me longer to figure out how to snap together the heart rate sensor than the TRX4500. :p. Needless to say the heart rate strap is much more accurate than the heart rate sensors on the handle bar panel and an overall nice feature to monitor. I literally just put it on and it began registering automatically on the TRX4500. *Warranty: Unlike most comparative models, XTERRA offers a lifetime warranty on the frame & motor. Having a lifetime warranty on the frame is one thing but a lifetime on the motor gave me a lot of confidence in buying the TRX4500. Combine that with a 2 year warranty on parts when just about every comparative model only gives a 90 day warranty says a lot on the overall quality of the product. *Machine Weight & Weight Capacity The TRX4500 listed weight is 220 pounds. It’s a nice solid & stable machine weight so it’s not sliding all over the floor when using. The usage capacity is 350 pounds which was on the higher end of comparative models. When u understand that impact weight is much more than ones physical weight grinding and pounding on the machine so having a capacity of 350 pounds reflects the sturdiness of the TRX4500. *Bluetooth Feature: The TRX4500 will connect with your iPhone or iPad. It comes with a connection cable that may be compatible with an iPod or android so bought an adapter for $7 to fit my iPhone. *Lift Safety Feature The lift feature is nice not just for space when not using but also for moving & cleaning under the machine. However, where I believe XTERRA didn’t capitalize on a marketing opportunity is that when you release from the lifted position, the TRX4500 will slowly decline so it doesn’t accidentally come crashing down on a small pet or child. Many comparative models do not have this safety feature. Additional Features (Not Worth Mentioning): Speakers: The speakers on the TRX4500 are adequate if you are plugging in an app from your phone. I read criticism in other reviews of the speakers but let’s be honest...you don’t buy a car for the stereo and u don’t buy a treadmill for the speakers. The speakers work fine but if you want higher-end quality sound then plug in a nice headset from your phone and you’re all set. The Fan: I read criticism the fan is a joke - and it really is. I don’t use it anyways as I’d rather keep a nice sweat going and if I really needed a fan I’d adjust the temp in my house or get a fan in my gym but I don’t see a fan on any comparative model being much different. The XTERRA APP: You can download the XTERRA app on your phone and there is much criticism on its simplicity but this is not a reflection of the TRX4500 treadmill. Don’t like their app then use a different app (simple as that). For me, the panel has all the info I need. OVERALL BOTTOM LINE: Before buying, I was never aware of XTERRA. I compared the TRX4500 to comparative models of MaxKare, Sunny, OMA, Horizon, Asuna, Nautilus & NordicTrack. And even to the next lower & higher XTERRA models (TRX3500 & TRX5500) & my results have found the TRX4500 is the BEST TREADMILL with the BEST FEATURES and BEST PRICE based on competitor models. As an additional testament, the XTERRA TR150 is an Amazon #1 Best Seller which adds confidence that XTERRA’s lower end products are well received and good quality, it should transfer over to their higher-end products like the TRX4500. And after using it, I’m very pleased with the TRX4500. In fact, I find it a better treadmill than the ones I used at the gym where I could feel the roller pins when running. In the TRX4500, the cushion & support are very nice and I know my knees and joints are much better for it. Because I put in so much time researching a treadmill, I went above and beyond in this review hoping it helps the next person who has no idea where to start (like me) when purchasing a quality treadmill. And as a final statement, I have to say I was not paid or a sponsor in any way by or for XTERRA (although they should pay me for this review). :p ---------------------------- JUNE 2025 PRODUCT UPDATE I bought the Xterra 4500 Treadmill in May of 2021 and over 4 years later - this is still the best treadmill ever! I have had absolutely no issues with this treadmill whatsoever. I haven't even had to adjust the belt. This treadmill is just as great as it was when I first bought it 4 years ago. Best decision ever!

I placed my initial order for this treadmill in mid-May, scheduling the delivery via Amazon for June 8th. The delivery window came and went, and yet I had received zero contact from the delivery company (NSD). I called them and got the runaround from their terrible automated service line. It wasn't until I contacted Amazon, then struggled to get to a live person on the line, and then had them contact NSD for me, did I finally learn that NSD didn't even have my treadmill at that time. NSD blamed Amazon and Amazon blamed NSD, but in the end I got a replacement treadmill set to ship out to me. We'll see if the next one actually manages to get delivered, and *then* I will update my review. What I don't understand, though, is why no one at either NSD or Amazon thought to contact me after this large & expensive shipment apparently vanished into thin air, instead leaving me to initiate the search myself after the delivery window had already passed. UPDATE: I received a call from the local delivery company a week after my treadmill was supposed to be delivered to tell me that they had received it and to ask if they could deliver it the following day. I said no, because I'd be at work that day, AND I had already arranged for Amazon to send out a replacement since it had apparently gone missing. They couldn't deliver the original treadmill because of that, so I had to wait for the new one. What I later realized was that the first treadmill never even got shipped out until the supposed delivery date of June 8th, hence why it arrived at the local delivery depot a week late. Well, in spite of Amazon assuring me that the replacement would be sent out ASAP, and despite the new theoretical delivery date of June 30th, it was of course still late. According to the tracking info, it was not actually sent out until the 30th. I don't understand why they're not shipping these things out until the "delivery date," but rest assured that if you order this treadmill, it will arrive at least a week after it's supposed to. Anyway, I finally got the replacement treadmill a couple of weeks into July (the earliest I was able to schedule a suitable delivery window with the local company), nearly two months after I actually purchased the thing. I opted for the free "bring it into the first room" delivery, because that's where it was going to end up anyway, so that worked out. I had to assemble it myself because I live alone and have no friends (yes, I know...very sad), and while it was doable and I got it put together without any mishaps, I chalk that up to the fact that I'm decently strong and have spent many years using many tools to build and fix many things in a workshop setting. The instructions are clear enough to someone experienced with such things, but I can see how they would be confusing at times to a layperson. It was a bit of a challenge to get this really heavy machine positioned where I wanted it after assembly, as well. If you're not mechanically inclined, and don't have your own better set of tools to use than the cheap junk that's included with the treadmill, then I'd recommend paying for professional assembly and/or getting someone to help you. Once I got it all put together and positioned, I was finally able to try it out. Fortunately, it works perfectly well! It's relatively quiet as advertised, the running surface is decently large, and the controls are pretty straightforward. I'm not going to be using any of the custom programming stuff, nor will I be using the built-in speakers, and the built-in fan is - as other reviewers have stated - a friggin' joke. Luckily, I have better speakers and a better fan here in the room already, so I've got all that covered. I'm just interested in doing some simple jogging and light running while I watch YouTube instead of sitting on my ever-fattening butt while I watch YouTube. Of course, I just HAD to strain a tendon in my knee on only my second time using the dang thing, and I haven't been able to use it since then... :( Once I heal up, though, I'll carefully work myself back up to the jogging and running. I've been patient for this long, so what's another few weeks, right? Sheesh...

This is really valuable product but the cost for which we paid....the vendor charged us installation charges separately This should have been informed / or updated as part of product description

Good stuff
