For instance, it has ergonomically designed handlebars with the built-in resistance control buttons and it can handle a user up to 325lbs. These are just a couple of added features of the Nautilus R618 Recumbent Bike.

It provides a better warranty on the frame with a 15-year warranty. There is an adjustable SightLine Dual-Mode LCD display that can be altered and tilted to give you a better view along with less glare. This model has the Nautilus Gel Seat that provides additional comfort. If you are like me, there are those days where I am into doing a long workout.

The Gel Seat will really be useful in those situations. Plus, if you have a bad back like I do the Gel Seat helps mitigate the pressure on your spine. My issues are all lower back and having the Gel Seat does make a big difference.

The Nautilus R618 Recumbent Bike does have 25 resistance levels and 29 pre-set workout options. This will add more of a variety to your workouts with some challenges.

This Bike has Bluetooth and can connect to sync up with the Nautilus Trainer 2 App for data exporting. In addition, the handlebars have quick control buttons for speed and resistance.

The improved Heart Rate Monitoring is even better with the Nautilus R618 Recumbent Bike as it is telemetry enabled and also has the contact pulse grips on the handles. There are extras like the media rack, acoustic chambered speakers, cooling fan, and so on. That is what makes this recumbent exercise bike a prime model.

You see the text "Fitness Sport Lifestyle" going around a red heart.

Having a higher capacity along with increased flexibility the Nautilus R618 Recumbent Bike is one of the top recumbent bikes on the market. It comes in at about $100 more than the Nautilus R616 model. The extended warranty alone makes it more than worth it for the additional cost.

If being able to experience professional quality cardio in your home sounds good? The Nautilus R618 Recumbent Bike is for you! Not to mention, you can use it whenever you want. There are no additional fees to pay like you do when going to the gym.  

This recumbent bike is a good fit even if you are just starting out or are a seasoned athlete that has been working out for years. Multiple people can use a single bike and can keep track of their data. It enables up to 4 user profiles to be saved and stored for future workouts and for uploading to different apps.

This recumbent bike is considered to have the most comfortable gel seats with back support making your workouts relaxed and enjoyable. There is nothing worse than a recumbent bike that does not have sufficient seat padding. I have been dealing with chronic pain for years with my back.

If I try to work out using a bike that has little to no padding, my back lets me know, and then reminds me again a couple of hours later just in case I forgot what it felt like.

There is a higher level of resistance setting along with a variety of preset programs that provide more challenging workouts when you want to take it to the next level. 

Assembly, Design, and Build

Nautilus R618 Exercise Bike

The Nautilus R618 Recumbent Bike has an Owners’ Manual that includes detailed image instructions that make the assembly go much smoother. 

The assembly process should not take more than a couple of hours. I highly suggest having more than one person assemble it. That will make the process go much easier. This recumbent bike comes with the necessary bolts, screws, and tools needed to put this bike together.

This is built with a sturdy steel frame and oversized crossbar tubing for providing greater stability. To maintain stability throughout your workout there are two integrated levelers that have a center support. This model is heavier than the R616 and R614 models weighing 107 lbs.

The bikes measurements are 48.8H x26.4W x67.3L and will support a user’s weight up to 325 lbs. They implemented transport wheels to make it mobile in the event you want to move it to another location. The handlebars are designed for efficiency and comfort along with incorporating the quick controls for speed and resistance.

It has adjustable pedals that come with straps for allowing you to maintain your feet position without slipping off while you are working out. 

Nautilus R618 Recumbent Bike Features

Resistance: The R618 uses the Eddy Current Brake System with magnetic resistance and 25 different levels to choose from giving you variety with your workouts. The control button for the resistance is conveniently located on the handlebars. This allows you to quickly adjust the settings while working out.

Comparing Consoles

A Young Lady with her arms out to her sides with her palms face up. She has a questioning unsure look on her face.

When you look at the Consoles it can be hard to tell them apart. The design of the R618 model is a little different looking. Both of them have dual backlit displays. One of the displays will always remain visible even if you use the media shelf and have a device on it. The console has tilting abilities to get the best view solely from your point of view.

They both come packed with 29 Preprogrammed Workouts and 25 Resistance Levels. Each bike allows up to 4 Users to customize a profile. They include Bluetooth Connectivity with the Nautilus Trainer 2 APP for your tablet, smartphone, and wireless heart telemetry.

As you can see the Nautilus R618 Recumbent Bike offers several more features than the Nautilus R616 Recumbent Bike. At first glance, it may not look that way but its apparent once you look into them a little further. 

The Nautilus R618 Recumbent Bike has its phenomenal Nautilus Gel™ Seat that’s essential if you have a bad back. The warranty for the frame is an amazing 15 years! Where the R616 is 10 years but that’s not too bad either. The Nautilus 618 is a recumbent bike that has the resistance controls in the rear handlebars. They have them attached at the end of each handlebar.

Not only is the R618 equipped with Bluetooth to be able to run features like the telemetry-enabled heart rate monitoring system, but it includes the wireless heart rate chest strap. In addition, you get the premium weighted foot pedals and the upgraded urethane-coated handles for durability. 

The R618 can handle a higher user maximum weight of 325 lbs and has a heavier frame to handle it. Finally, it has a longer electronics warranty of 3 years where the R616 only has 1 year.

My Thoughts

This is a thought bubble that's empty.

I put the features of the Nautilus R618 and the Nautilus R616 side by side below. Both of them are great recumbent bikes but my choice the R618. Why? Their trademarked gel seat is extremely comfortable. As I mentioned, I have chronic back pain, and sitting on seats with little to no padding can be torture for me.

The extended warranty tells me Nautilus really stands behind their product and having that extra assurance in case anything happens is always good to have.
