To begin with, some people might find this frame heavier as compared to other Nautilus recumbent bikes. Nautilus R618 recumbent bike has a one-piece construction made from steel tubing. However, the weight is optimal enough for convenient relocation. There are two transport wheels added to the front base for easier mobility. On the contrary, the rear base is designed with the handle for easier lifting and can be leaned on the transport wheels.

The recumbent bike is integrated with the step-through design that makes it equally great for people who have physical disabilities. Also, the steel construction promises resistance from corrosion. As for the rail, it has an aluminum construction and promises a natural appearance.

Various PVC parts in the recumbent bike enhance the protection. For better protection, there are covers for the drive system, seat base, along with seat rail caps. As far as the seat is concerned, it has a gel cushioning with a thick layer; it also has a contoured design that aligns with the body without sacrificing comfort. Also, the backrest has PVC construction with a vented design that reduces the chances of overheating.

The angle of the backrest is adjustable, hence various adjustment positions, and users can use the lever for controlling the position. The seat is adjustable since there is an aluminum rail. There are two sets of handlebars available and are integrated with resistance controls and pulse sensors.

Resistance & Drive

Nautilus R618 recumbent bike has a motor-assisted magnetic resistance system, also known as an eddy current brake. It is also integrated with the magnetic resistance pad with which the resistance can be adjusted through the console. This means that whenever users adjust the resistance level, the position of the servo motor will change. The recumbent bike needs to be connected to the AC power adapter or power source since it doesn’t have a self-generating power system.

There are twenty-five resistance levels available in this recumbent bike that’s suitable for intense workouts, as well as, for low-impact fitness sessions. There is a magnetic resistance system available in Nautilus R618 recumbent bike, along with the heavyweight flywheel and belt drive, hence you can expect a smooth motion.

Truth be told, this recumbent bike is pretty heavy, which means it demands at least two people for assembling. The resistance components and drive are pre-assembled, so you only need to connect the mainframe and base tubes. On the top, the backrest, handles, handlebars, and seats can be assembled. Generally, the assembly will take around an hour. Besides, the tools come with packaging for assembly and the manual has detailed instructions.

In a Nutshell

Overall Score


  • Top-grade construction and study frame
  • Easier mobility
  • Bluetooth and app connectivity
  • Resistance controls
  • Easy to read console


  • Weak cooling fan

The Final Verdict

Featured with the top-grade construction and sturdy frame, this recumbent bike is an apt image of durability. The availability of resistance controls helps customize the workout while the console is easy to read. The only point of concern is that the cooling fan is not powerful enough, so there might be heating issues. As for the tablet covering the top display, you can always use the smartphone!
