Inertia-enhanced Flywheel

It's important to choose an exercise bike that will last, and the material of the frame determines how durable the bike is.

Our Rating

Rating: 93.35/100. This bike really shines. First, you get a large 14” HD Touchscreen. This will make following along with any streamed programs you use easy- you’ll never feel like you’re straining your eyes.

What’s more is that the screen will actually swivel around so you can use it while you are off the bike to do strength training or a HITT workout. Since you can also stream guided strength training workout sessions, this makes it ideal for those who really do want to go that extra mile in order to reach their fitness goals. This is more than just a bike – it’s essentially a full workout machine.

Moving down the bike, you have a durable commercial steel grade frame that can support up to 350lbs. of user weight. This means that just about everyone should feel comfortable riding this bike, no matter what intensity level they want to reach.

You’ll also get an inertia-enhanced flywheel, which makes for a smooth user experience, and a SMR Silent Magnetic Resistance feature, so you can cycle in complete quiet.

The bike offers one touch controls so adjusting the resistance or incline is going to be easy as a push of a button. You’ll never have to interrupt the flow of your workout to achieve the resistance setting you need.

One of our favorite features of this bike is the fact that it offers decline and incline capabilities. This really sets this bike apart from others on the market as this is a relatively rare find and something that will help take your workouts one step further. By adjusting the incline, you can mimic riding up a real hill, giving you the illusion of an actual course that you may be cycling on race day.

Cycling downhill is also a great option if you are doing HIIT and want to really reduce the intensity level without necessarily taking the resistance way down.

There isn’t really anywhere that this bike falls short, expect for potentially not having a reading rack where you could place an iPad, phone, or book. With the large screen that it comes with however, most people are not going to find they really need one.

The labor warranty on this could also be slightly longer, however one year is quite standard in the industry so isn’t way off base.
