NordicTrack GX 4.6 Pro Exercise Bike Review

NordicTrack is not a brand known for sitting on its laurels, even though it does have some sizeable laurels to sit on! When we spotted that the NordicTrack GX4.6 Pro had an electromagnetic resistance system we got all giddy and had to take a closer look. Here’s what we found.

With a footprint of 110.7cm x 63.2cm (43.6” x 24.9”) and weighing in at 47kg the GX4.6 Pro is a substantial bike. Despite this, the assembly process is simple and took no time at all (less than 30 min). It’s a good looking bit of kit too and is made to look all the smarter because of the 7″ full-colour touchscreen console display.

Ergonomically, this is a very good bike. There’s plenty of adjustment available yet whichever settings you select, the riding position remains comfortable and technically sound. This comfort is a testament to the knowledge that NordicTrack possesses when it comes to building exercise bikes. The saddle is nice and wide and well-padded while the pedals are oversized making this model suitable for more or less everyone.

The resistance system used here is electromagnetic rather than servo-motor. In plain English the benefits of this are two-fold: no moving parts equals significantly superior levels of reliability, and secondly the speed at which the resistance changes, enables very effective high-intensity interval training sessions. It feels amazingly responsive with a very swift change of resistance, even from min to max within just a few moments. The use of this system should, in theory anyway, mean that the single most common point of failure on an exercise bike (servo resistance motor) has been removed and replaced with something that will rarely, if ever, go wrong.

The console as mentioned earlier has a 7″ touch-screen display at its heart but NordicTrack has been savvy enough to retain the physical buttons for the most important in-workout functions; resistance adjustment +/-, cooling fan control and most importantly the quick resistance keys. Most importantly because this is an EMS bike with an electromagnet which means that when you press those max and min resistance keys, you can expect to get there fast as it delivers a slick, quick response to your commands. If you’re into your interval and high-intensity training you’ll appreciate that. It works an absolute treat on this bike and once you get used to it, it does make other traditional bikes feel sluggish and unresponsive. They’ve also left the sound level control for your music on a physical button too, which makes controlling things in the middle of your workout much easier than trying to touch the screen with sweaty fingers.

Aside from these functions, all other operations including programme selection are carried out via the touch-screen interface. Unlike most other exercise bikes, the GX 4.6 Pro requires a WiFi internet connection in order to access the workouts, though you can exercise in manual mode without one. The reason for this requirement is because the workouts here are not a set of preset programmes built-into the console itself. Instead, there are 50 workout videos to choose from which are streamed to the bike as and when required. The videos themselves are engaging with a personal trainer guiding you through each session and helping to motivate you throughout which you can really start to appreciate as you near the end of the workout and might be tempted to slack off a bit! The videos are categorised in the same way as traditional programmes with videos that focus on weight loss, or cardio improvement and so on so it’s a simple task to pick out the kind of workout you want. This couldn’t be much further away from the way almost all other exercise bikes deliver a training session – it’s superior and is particularly great at keeping you involved and interested, something that’s bound to appeal if you find it hard to stick to an exercise programme.

In addition to the 50 workout videos, this bike is being sold including a 1-year Family membership for iFit® Coach. This gives you access to a vast library of more than 400 additional workout videos as well as Google Maps based rides that you can create yourself. It also gives you access to a myriad of other features including races against other members, dietary and sleep advice and a lot more.

There’s also a tablet holder, a Bluetooth® smart wireless receiver (refreshingly a chest strap is included), dual speed cooling fan, stereo speakers, a water bottle holder and a 5-year frame, 2-year parts and labour warranty as well.

Review Summary - In Brief

The NordicTrack GX 4.6 Pro is a very good exercise bike. It's well built, has a comfortable well-padded saddle, provides a great riding position for pretty much everyone and has a silly number of ways to train. It also features effective and engaging video workouts. The electromagnetic resistance system should provide years of hassle-free service and changes at lightning speeds compared with a servo-resistance based bike. And here's the thing, for what you get, this really isn't an expensive bike. The value for money it represents is very good indeed. At the current price, if you're looking for a premium exercise bike, this a great choice and certainly one of the very best in this price range.
