NordicTrack S15i vs Grand Tour Pro – Which is the BetterCommercialBike?

 NordicTrack have designed some of the world’s most cutting-edge and price-friendly stationary bikes. Which between the S15i and Grand Tour Pro is the best exercise bike?

I have worked with NordicTrack equipment exclusively for the last three months to know that they have less differences between them compared to similarities which makes it incredibly difficult to select one over another.

These bikes from their collection of the NordicTrack Studio Cycle, provide you with high intensity calorie burning training programs in the comfort of your home.

An obvious difference that may be immediately spotted is the difference in the size of their LCD monitors.Another less obvious difference lies in their level of resistance.

The Grand Tour Pro, being that it was modeled after the S15i, has been bumped up 2 levels from S15i’s 22 to the now 24 levels of resistance.

NordicTrack S15i vsGrand Tour Pro– How do they compare?


Both bikes use a magnetic flywheel resistance which can be automatically controlled based on your cycling intensity and by using the button controls on your handlebar.

Handlebars coated with firm rubber grip are built into both bikes and they both can hold two water bottles. NordicTrack comes with 3-pound dumbbells which boosts your training options with racks provided for easy accessibility.

One of their best features is that NordicTrack can raise and lower in incline and decline simulating outdoor cycling better with realistic resistance levels. The range of incline or decline available is between 10 to 20 degrees.

With speakers located at the back of the console, this is the only drawback we could perceive. Either way, the quality of the speakers is great and the volume regulation is possible with buttons found on the side of the console or through the LCD touchscreen.

Both bikes have great functionality because the resistance is automatically adjusted, you can incline and decline the bike and they even threw in dumbbells to compliment your training.


Both the NordicTrack S15i and the Grand Tour Proare built of corrosion resistant steel which guarantees you a lifetime of use. They both have an inertia-enhanced flywheel which relies on your workout intensity to increase or decrease resistance.

This means that the harder you work out, the faster the wheel turns. To safely stop the wheel at high revolutions per minute, the NordicTrack team added an emergency stop button.

The pedals are quite unique for both bikes, the NordicTrack is easily set up with two-way pedals meaning you can either use the side with the toe-cage or, if you prefer to, you may opt to flip the pedal to ride on the flat surface like on an outdoor bike.

If you wish to, the pedals on these bikes could be swapped for other alternatives if you have a specific type of pedals that you like to cycle on. They both can hold up to 350 pounds. If you have some special cycling shoes, the pedals provided are compatible with clip-in mechanism.

I highly recommend both bikes because they have versatile pedals that do not require special cycling shoes to ride.

Riding Experience

NordicTrack S15i has a 14-inch touchscreen while the Grand Tour Pro feature a 22-inch screen that display vital information and help the user connect with the virtual trainers and spinning classes available. Both bikes feature a camera attached to the screen with speakers at the back.

Both bikes have the ability to screen cast the bike to an external screen like a TV with a HDMI port on each side of the screen for ease of connection. These screens can also be tilted up or down to allow different users to view at the best angle possible for their height.

S15i and Grand Tour Prohave an extra feature that incorporates a cooling fan on the sides of the screen to help you cool off mid training.

With both bikes, you can raise and lower the handle bar height, seat post, move seat forward and backward and align the angle. They have quality road bike seats that are adjustable in two ways while the handlebars are only one directional.

NordicTrack S15i and Grand Tour Pro have the added benefit of a cooling fan for the user which is something that makes them both very comfortable to cycle on.

Conclusion: So, which between the NordicTrack S15i and Grand Tour Pro Bike is the better Commercial Bike?

Grand Tour Prois hands-down the best commercial bike for the sole reason that it gives you an iFit Bluetooth enabled chest strap that is missing in the S15i. however, the S15i makes up for this by enabling you to connect to it seamlessly, if you have a Bluetooth heart rate monitor.

Other than that, both NordicTrack bikes are great selections for anyone and everyone who loves cycling as a workout.
