The Buzz

Nautilus U616 Console

Critics like the new Performance Series, and the U616 is currently the most popular model.  it is well-priced at under $600 when it's on sale, and it has plenty of features and capabilities to keep you satisfied.

The company is known for their wide variety of built in programs, and the U616 has 29 in total: a Quick Start, 4 custom, 12 profile, 9 heart rate, 2 fitness and 1 recovery.  There's plenty of variety mixed into the workouts, and you can also change up your resistance manually with 25 different levels to choose from.

The bike feels smooth and transitions are relatively seamless.  You can measure your heart rate with the grips or if you have one, a wireless heart rate monitor.  Note that the top-of-the-line U618 model has the chest strap included.

The DualTrack display is large and bright, and although it is a bit busy it doesn't take long to get the hang of it.  It gives you all of the relevant feedback that you could want from your workout.

Speaking of your workout, you can track everything via the NautilusConnect app using Bluetooth, which can be synced with MyFitnessPal as well.  That way you can keep on top of your workouts, set goals for yourself and even share all of your results with your friends and family.

All in all the U616 is a very good entry level upright from Nautilus, and a nice step up from the base U614 with more workouts, more resistance levels and Bluetooth, which the U614 does not currently have.

Our Take on the U616 Upright Bike

We like the U616 as it gives you a lot of bang for the buck.  You get a large number of solid workout programs, plenty of resistance levels, oversized seat/pedals, bright display and smooth eddy current brakes.

It doesn't come with a heart rate monitor like the U618, but it has enough to keep you satisfied and motivated to reach your fitness goals, whatever they may be.
