The Nautilus R618 Recumbent Bike is ideal even for professional cyclists. It comes with state-of-the-art features, including Bluetooth and compatibility with iFit. Combined with the 29 workout programs that comes automatically with the bike, you can push yourself physically like never before.

Is the Nautilus R618 Recumbent Bike best for you?

You don't have to spend an arm and a leg to get a high-quality exercise bike, and the Nautilus R618 proves it. The extra-wide, ventilated seat is a major step up from other devices in its price range. For added comfort, you also receive weighted pedals that force you to really push yourself to get in a solid workout.

It's easy to start using this machine, and you can make it work ideally for you with the Adjustable Sight Line tilting console. This allows you to move the console depending on your height so that you can optimally view your stats. A water bottle holder, USB port, and sound system are just some of the other perks you're bound to enjoy.

Consider Nautilus R618 Recumbent Bike if...

  • You need apps in your workouts. This bike is compatible with MyFitnessPal and the Nautilus app. These open up other programs to you as well as help you monitor your progress.
  • You want adjustability. The seat, pedals, and console can all be moved. That means you can set it for the exact angle that's optimal for you.
  • You like a ventilated seat. The reclining seat features ventilation. This helps keep your back cool while promoting healthier blood circulation.

Avoid Nautilus R618 Recumbent Bike if...

  • You need an integrated tablet holder. If you want your tablet and screen visible at the same time, you're out of luck here. You can rest the tablet on the holder, but it covers the screen if you do so.
  • You want a stronger fan. The Nautilus R618 does come with a cooling fan. However, many reviews note how it isn't that strong.
  • You want easier-to-find replacement parts. In the event the seat ever breaks, you may have a difficult time tracking another one down.
