From the moment you take it out of the box, the Nautilus R618 Recumbent Bike is a solid piece of equipment that feels more like a rig for a gym than a home workout machine. It’s built like a tank with a heavy-duty frame that can support riders weighing up to 300 pounds. The heart of the machine is its padded seat that can be adjusted to fit nearly any height and an adjustable backrest that can be locked into five different positions.

A built-in cooling fan, a cup holder and pocket work great for keeping you motivated as you pedal away. The LCD display is easy to read and shows your speed, distance, calories burned and time elapsed since your last workout. With so many features and impressive construction under the hood, it wasn’t hard to imagine this machine would cost a lot more than it actually does.

Let us quickly enter the review of this recumbent bike, I hope this review can help you make a decision whether it is necessary to buy.

First, please watch the video introduction of this Nautilus R618 Recumbent Bike.

Feature of Nautilus R618

The R618 makes a big impact on your ride, with a sleek design that incorporates ergonomic handlebars, high-speed flywheel and a power meter.

The R618 is also available with Performance Series upgrades, including a 20-inch, high-resolution touchscreen, Bluetooth® connectivity, and free app-based tracking tools, which allows riders to stay connected to their fitness goals.

A built-in fan keeps you cool while the integrated tablet holders let you watch videos and follow along with the provided training programs. The R618’s adjustable airflow system increases resistance by channeling air directly into a rider’s face for a more intense workout.

The following is a detailed introduction of product features.

More Stable Framework

Nautilus R618 recumbent bike is an upgrade of R616 and R614. There has also been an increase in the weight of the bicycle, about 107 pounds, which means the following three points:

  • First of all, the stability of this recumbent bike is increased, making the user more at ease when riding fast.
  • Secondly, the upper limit of the larger weight capacity. Yes, this R618 recumbent bike can withstand a maximum weight of 325 pounds, while the maximum weight of a typical recumbent bike on the market is 300 pounds or less.
  • Third, it is difficult to move. This is obvious, but there is no problem for the Nautilus R618, because it has two transport wheels on the front seat. In this case, even if the entire frame weighs tens of pounds, you will not have any difficulty moving it.
  • Fourth, it may be larger. Indeed, this recumbent bike is not compact and will be a bit bigger than the average. Its entire size is 67.3″ L x 26.4″ W x 48.8″ H. If you want to put it in your home, please measure the space first and leave a distance of at least feet for the front and back.

More Comfortable Seats

This comfort is not my personal feeling of sitting on a bicycle for a long time, but the feeling of most users after experiencing the R618 and R616 at the same time, as well as some other recumbent bikes. All this is due to the Nautilus R618 equipped with an upgraded gel buffer layer.

We all know that the seat is very important for a recumbent bike, especially if you plan to use it for a long time to exercise. A more comfortable seat can increase the overall exercise experience, thereby increasing the length of exercise.

Of course, for this upgraded version of Nautilus R616, its seat is of course also adjustable.

Adjustable and Ventilated Backrest

The backrest is as important as the seat, and it is also the biggest difference from ordinary upright bikes. More importantly, many people who use recumbent bikes are people with back injuries. In this case, the comfort of the backrest is even more important. It is like a car seat, only adjustable can it meet the needs of people of different sizes. The good news is that most of the recumbent bikes on the market take this into consideration.

But one thing that many recumbent bikes do not consider is the ventilation of the backrest. This is a very useful design during long workouts. Because long-term exercise will cause sweating, if there is no extra air to circulate in the back, it will easily cause the sweat to be unable to dissipate and the blood circulation will not be smooth. Longer time, it will affect your exercise effect.

Fortunately, the backrest of this Nautilus R618 is made of heavy-duty PVC material with a ventilated design, which solves the problem of perspiration during exercise.

Multiple Resistance and Workout Program Options

Resistance is the core of a recumbent bike, and a higher resistance level range allows users to more steadily improve the exercise effect. The resistance level of this Nautilus R618 ranges from 0-25, level 0 allows an injured elderly person to perform recovery training, while level 25 is very difficult for professional cyclists, generally want to use recumbent bikes may not reach this level for low-intensity exercise.

The workout program is used to enrich the experience of recumbent bikes, and more built-in workout programs can make the user’s exercise more diversified, rather than boring and riding at a constant speed. For example, interval training is considered to be the most effective way of exercise. This Nautilus R618 provides up to 29 built-in workout programs, which is more than most recumbent bikes on the market.

In addition, it also has the most user profile among recumbent bicycles currently on the market. A total of 4 user profiles can save the exercise settings and data of you and your family and will recommend different exercise plans to different people according to different preset conditions.

Clear and Easy-to-read LCD Screen

As the highest-level model of the Nautilus R series, its display screen is certainly not bad, with two blue backlit displays. The blue backlit screen is clearer than the general screen, even in the case of poor external light.

All exercise-related data displayed on the blue backlit screen is rich enough as a mid-to-high-end workout equipment. It covers basic time, speed, distance, RPM, resistance level, calories burned, and heart rate. The point is that the heart rate measurement method can be measured by hand-held handles or wirelessly. Both methods are very accurate.

More Advanced Features

In my opinion, the above features are all necessary for a recumbent bike, and we can see that the Nautilus R618 recumbent bike has done well enough. Next, let’s take a look at what more advanced features it has to make it a better recumbent bike.

  • Bluetooth Connectivity. This is obviously an advanced feature, which allows you to connect your mobile phone or tablet via a wireless network to synchronize your exercise data to the Nautilus Trainer 2 app. And some low-end recumbent bicycles only have USB ports, and some do not even have any way to connect to smart devices.
  • Explore the World App. This is an online application that allows you to connect to smart devices such as mobile phones or tablets via Bluetooth, allowing you to perform real-life cycling exercises based on the virtual route of the GoogleMaps route. In addition, it is also like a Facebook in the cycling world, interacting with friends who love the same online.
  • Sound system compatible with smart devices. Some people like shocking music during exercise, while some people just like quietly focusing on the exercise itself or simply watching some TV shows, so this is not necessary.
  • A three-speed cooling fan. This is also an add-on for a recumbent bike. With it, you don’t need to put a fan in front of your equipment.
  • Built-in Water Bottle Holder. If you use the Nautilus R618 recumbent bike at home, this is also optional.
  • Better warranty. 15 year frame, 3 year parts, 1 year labor warranty. These are all improved on the basis of Nautilus R616, which has 10 year frame, 2 year parts, and 90 day labor warranty. Obviously, Nautilus is more confident in the quality of the most advanced product of the Nautilus R series, otherwise they dare not promise a warranty of more than ten years.

Final Conclusion

In general, the Nautilus R618 recumbent bike is a recumbent bicycle with very comprehensive features and its advantages outweigh its disadvantages. It is reasonably priced, has a stable overall frame, a more comfortable seat, an adjustable and ventilated backrest, more resistance levels and a rich exercise program, as well as additional functions to improve the sports experience.

In summary, I would definitely say that the Nautilus R618 recumbent bike is one of the best recumbent exercise bikes on the market. However, if you want to save money, you can choose the Nautilus R616, which is nearly $100 cheaper. It’s just that the seat is not as good as the Nautilus R618, and the overall warranty is shorter than that of the Nautilus R618.
