Proform Power 525i Treadmill Review

With a breadth and depth of experience that few other manufacturers can match, Proform have an excellent track record for producing quality home-use treadmills to suit a wide range of budgets and needs. What all the models in the current range have in common is a high specification for the money being asked and a build quality that should see the machine lasting the distance. But just what is your money buying you, and can you really get a high-quality treadmill at a distinctly budget price point? We took a close up look at the Proform Power 525i treadmill to try to get a definitive answer to these questions.

Assembling the 525i is most definitely a two person job but not a complicated or particularly difficult one. The instruction manual is clear with well-written instructions (no Chinglish here we’re pleased to say) and clear well laid out diagrams. It doesn’t require professional installation and as all the moving parts are pre-assembled it’s really just a case of one person holding things in place while the second person screws it all together. There aren’t too many assembly steps either so assembly was completed within the hour, so far so good. Just a quick note here to say that it’s worth making sure your recycling bins have some space as this treadmill comes very well packed indeed!

The advantage of all that packaging was that our test model arrived in pristine condition, which is no mean feat for a box of this size and weight that contains both heavy lumps of metal and delicate pieces of plastic. The 525i, like many other models in general, doesn’t have any leg levellers so an essential part of the set-up is to ensure that the machine is on a flat floor, else you’re running the risk of hearing knocks and squeaks when working out. Thankfully, once placed correctly, our test model was rock-solid on the floor with no movement at all of the base unit. The crossbar that runs between the two metal uprights also provides a significant level of added rigidity compared to a treadmill without such a crossbar, so overall the 525i feels very solid indeed.

With a footprint of 183cm x 83cm (72″x 32.6″) when unfolded and a weight of 82kg (181lbs), the 525i is certainly not a lightweight bit of space saving kit. While it’s not the biggest treadmill in the world, it is big enough to get a good run on. The  140cm x 46cm (55.1’’ x18.1’’) running area provides enough room to move around on during a run, though at 46cm wide it’s a bit narrower than we’d expect to see on a treadmill that isn’t being marketed as a space saving model. Most users of 6ft 3″ or less will find that they’ve got enough space here in terms of the length of the deck, but some may find the width a little bit restrictive. The deck itself is well cushioned without being overly soft. Proform have stuck to their tried and tested ProShox™ cushioning system here and that’s no bad thing. It’s very well balanced between providing a cushioned landing and a firm surface from which to launch so the chances of developing shin splints or other injuries should realistically be little to none as a result of the cushioning set up on this treadmill. Of course, one of the most important aspects of a treadmill is how it feels when you run on it and the set up here is one that’s going to suit the vast majority of runners. Jogging at low to medium speeds is comfortable with the launch feeling natural (no unwanted, excessive springiness here) and the landing soft, while running at higher speeds provides the same launch but with a landing that does enough to absorb the shock without being overly soft. It feels good and while some seasoned road runners prefer a harder landing to be closer to road running, for the average runner the 525i will deliver an enjoyable and comfortable run.

The fundamental technical specs on the 525i make for pretty good reading. It features 1.6″ (4cm) diameter flex resistant rollers at both the front and rear and a substantial 2.5 horsepower motor. The combination of good-sized rollers and decent sized motor means that even at higher speeds the noise level is kept respectably low. Let’s be clear here – a 2.5 horsepower motor is respectable for any treadmill but when you look at the price of the 525i it’s really very impressive indeed. There are many, many significantly more expensive machines that have smaller motors (sometimes a lot smaller) than this and for the money being asked it’s a surprise that Proform have opted to use a motor this big this in this model. It shows that they’re serious about gaining an advantage over their rivals.

In terms of incline, the 525i uses a secondary motor to lift the running deck from a flat position up to a respectable 10% incline at the touch of a button with quick access keys on the console to let you reach a preset incline level with a single button press. The top speed available is 11mph (18kph) which is plenty for all but pro runners, and this combined with the 10% available incline means that this is a treadmill that can push most runners hard.

The 525i uses a high contrast LCD display to deliver your training data so the vast majority of your data is displayed simultaneously making for easy tracking of your workout. The display can be adjusted for contrast and the units of measurement can be changed from KM to MPH. The screen is easy to read and the data is clearly and logically laid out, as are the control buttons. The preset workouts, of which there are 20, are divided into separate categories such as Incline, Calorie, Intensity, Speed and so on. While this can feel a little counter-intuitive at first, it really doesn’t take long to get your head around the way things work and selecting and starting a preset workout is very quick and simple. The screen tells you where you are in your workout so it’s easy to see how far you’ve got to go and as you’d expect from a seasoned manufacturer it all works seamlessly and without any bugs or unexpected hiccups. For a manual workout, it’s as simple as pressing start and then adjusting your speed and incline using the buttons on the console. There aren’t any speed/incline adjustment keys located on the handlebars here which is a bit of a pity.

Like all new Proform treadmills, the 525i is iFit compatible. Subscribe to iFit (30-day family subscription included) and you can stream more workouts, track your fitness improvements, plus the software is powered by Google Maps, so you can plot your own running routes anywhere around the world. There’s a Bluetooth connection available as well so you can connect a smart device and access your iFit account while running so you can actually see your progress on the map. iFit does a whole lot more than this and if you want to know the details it’s worth going to the iFit web site to get all the information.

While the 525i does feature hand-pulse sensors so you can measure your heart rate, it also has a built-in wireless heart rate receiver that will work with any Bluetooth Smart heart rate transmitter. Our test model worked perfectly without any issues at all and as far as we could tell, didn’t miss a beat. The console unit also comes with built-in speakers, audio input port so you can plug in a music player, two integrated water bottle holders, key holder and a tablet holder that’s positioned at the top of the console so you get a clear view of the screen in a natural position as you run.

The manufacturer warranty is provided in the form of lifetime cover on the frame, 5 years on-site cover on the motor and 2 years on-site cover for parts and labour.

Review Summary - In Brief

The Proform Power 525i really is quite a decent treadmill. It's got a reasonably comfortable, well-cushioned running deck. It has a powerful, high-quality motor and it's well manufactured. There's really a lot to like and not much to not like. All around the 525i is a solid running machine with a large number of ways to train which makes this a very good choice for most home users. But, there is one reason not to opt for the 525i and that's the Proform 545i (the next model up). The 545i has the same motor, top speed, incline, and number of programs as the 525i, but benefits from a significantly wider (51cm vs 46cm) running deck and larger (1.9" vs 1.6") rollers.  It's on offer right now so will save you over a hundred pounds in the process while delivering that bit more.
