XTERRA Fitness Sport Series Premium Folding Smart Treadmill, Handlebar Speed and Incline Controls, Large XTRASoft Cushioned Running Deck, Built-in FTMS-Enabled Bluetooth with XTERRA+ Fitness App

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 ControlsAs 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 MonitorAs 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 & LayoutIn 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 & InclineThe 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 MotorI’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 AssembleI’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 SensorIt 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 CapacityThe 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 FeatureThe 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

Excellent treadmill, not quite commercial gym quality but solidly built with sweet blue LCD screen and Bluetooth FTMS that works great with Zwift and Kinomap. I put this together myself but had to lay on my back and hold up the verticals with my feet using my hands to connect the wiring and bolt the verticals to the base, definitely a job meant for two people.The box is huge and heavy, looked okay but my motor cover was cracked. Called Spirit and they registered the treadmill and shipped me the replacement cover. Kudos to Spirit for answering the phone quickly and taking care of the shipping damage without any hassle.I am 6'-0", 235# and jog, run intervals and race pace on this thing no problem. The motor is powerful enough and the frame sturdy. Mainly use the treadmill with Zwift and Kinomap. Zwift works fine but they still won't implement auto incline control so it isn't as seamless as it could be. Kinomap however does control the treadmill's incline and it is really nice, but the video quality is hit or miss. Bluetooth FTMS works great on the TRX4500.Pure manual mode is nice too. The readout shows not only speed in mph but pace which is nice and you get a visual of a track which helps with intervals.When jogging and running, the console does shimmy so trying to watch Netflix on your tablet is going to be frustrating, but you're golden if you are just going to be walking. I'm using a stand mounted TV for the running apps and watching YouTube or Netflix so it's a non-issue. The True and Life Fitness treadmills at the gyms I go to are more solid with just a bit of mild console shimmy when running. The Xterra has about the same I noticed in the Soles, Proforms and NordicTracks I tried out before buying the Xterra.Overall a solid treadmill capable of running and interval training with linebacker sized runners, FTMS Bluetooth for Zwift and Kinomap and a great value.

We wanted a treadmill for the cold winter months. After a lot of research we purchased the TRX3500.First, this treadmill is big! It is shipped in a huge box on a shipping pallet. It's not by any means compact and easily movable. It also does not really fold up nicely for storage.Assembly takes more than one person, was frustrating at times, and took about 1.5 hours with three people. Some of the screw holes simply did not match up.The control panel is not fancy, but is very simple to use.UPDATE: Our only complaints are...1) the side arms are too short for walking, if you need the side arms for stability and support2) the side arms are too thick to grip comfortably3) the fan provides little to no air flow4) the two User profiles should be first in order rather than last. You need to scroll through all of the 30 pre-programmed workouts to get to your customized workoutsHowever, this treadmill is sturdy, is relatively quiet, and provides a good work out. After about a month of usage by two people everyday, we like this treadmill so far.

Good stuff

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