NordicTrack GX 3.9 Review

NordicTrack make some fantastic cardio equipment, their 2021 line of products are looking like they’ll actually compete with Peloton, Echelon & offer the ultimate coaching experience. However, that range of equipment isn’t the most suitable for those shopping on a budget, even I don’t have £1,000+ to spend on a cardio machine.

The exercise bike in their range that took my eye was the GX 3.9, which is undoubtedly an affordable machine for everyone. In this post, I’ll be looking at this & reviewing it against it’s ‘older’ brother, to see if it actually packs a decent punch for the cost.

Notice from Tom – HGR Team:
Frustratingly, I could only review the GX3.9 against the Grand Tour Pro exercise bike, as they are the only two machines in that series.

I could have reviewed the GX4.4/4.6, but they’re completely different bikes and the results would make no sense. Sorry, I hope you understand!

Without hesitation, let’s get into this NordicTrack GX 3.9 Review & learn more about this exercise bike.

Are you looking for an Indoor Exercise bike which offers an immersive experience, whilst not breaking the bank? I can’t stress how important that equipment cost is and the NordicTrack GX3.9 definitely ticks the boxes for being good value.

NordicTrack GX3.9 Exercise Bike

A Fantastic Indoor Cycle
initial thoughts
Although this is a solid exercise bike, I was really looking forward to testing an iFit compatible bike. Let’s be honest though, you won’t find a bike with this spec for sub-£700… yet alone £399. I actually really like the design of this bike, the Matte Silver & Black colours won’t look out of place in any home gym.

NordicTrack GX3.9 Exercise Bike Review

In-Depth Review

Founded in 1975, NordicTrack began manufacturing Ski equipment. They quickly expanded to other fitness equipment, where they soon found their segment with Cardiovascular machines. Now, they are owned by Icon Fitness, a huge player in the fitness game. They own iFit, NordicTrack, Proform Fitness & Weider to name a few.

The equipment that NordicTrack produced is designed specifically for home use, with ease of use the centre of their focus. Their equipment ranges from £399 to £3,499. Today, we are focusing on the GX3.9 which is their £399 model.

Sitting just short of 120cm long, the GX3.9 is a good sized bike, compact enough for your home gym requirements. It supports a 115kg maximum weight, which means it’s adequate for most. If there’s enough weight allowance left, you could also add a weighted vest into your workout for even more resistance.

That may be overkill though, as the 18kg flywheel should offer sufficient resistance for you when exercising. I was quite surprised by the 18kg flywheel, as most bikes with this size are over £700. You would expect one of the biggest brands to follow suit, but it appears they’re breaking barriers down with this exercise bike.

I’m left scratching my head with this one, as I’m looking for where they’ve managed to cut down on costs. The gel padded seat is comfortable enough for your workout needs, albeit not comfortable enough to the point where you’ll consider selling your sofa. The same seat also adjusts horizontally, aswell as vertically which means that all heights have been taken into consideration.

What this system does lack, is what makes it hundreds of pounds cheaper. The presence of a physical integrated display is the reason why this bike is priced so competitively. Other models like the GX4.9 have an in-built, pretty looking display console whilst the GX4.6 pro has the complete iFit experience.

The GX3.9 has a less pretty looking, battery assisted LCD console, which offers calories, distance, odometer, scan, speed and time readings. This is the only let down, but I can’t say that I expected a higher quality device or the bike would’ve been £599, instead of £399.

The 18kg flywheel will offer an immersive experience, making this a fantastic alternative for when you can’t hit the tarmac on your road bike. Typically, the heavier a flywheel, the smoother the performance. NordicTrack thought of everything even with this lower end model, supplying the pedals with toe cages & straps to secure your feet in place.

I think for £399 it’s a great exercise bike for beginners, or someone who needs to put in a few hours cardio per week. It’s priced very well & the competitors in this price range are less-known bikes, whereas with this you get the NordicTrack engineering excellence.

If you are a more seasoned cyclist, you may want to consider the below table as we compare various bikes that NordicTrack offer, including the vital differences.

  1. have a new 3.9 sport model, however the console will not display in kilometers no matter what I try, any idea’s?

    • Hi Jim,
      Have you tried this?

      For an elliptical or bike press the RESISTANCE UP arrow button to take you to ENG2. Press the ENTER button. Now press the START button, the display will change between Miles and KM (Kilometers). Once it is displaying the desired output, press and hold the STOP button for 3-5 seconds to exit the menu.
