Features and Specifications

At its price, it’s just right to expect that the Nautilus U618 Upright Exercise Bike is packed with advanced features, including those that are briefly mentioned below.

Dual Mode LCD Display

This is one common feature that you will see in many of the exercise bikes from Nautilus. This will let you make the most out of the display as it shows a lot of information for tracking your progress. You will always be in the know of how you are doing and you can adjust your workout accordingly.

Multi-Position Handlebars

To promote your highest level of comfort, you will love how it comes with multi-position handlebars. You will have complete control of its angle so that you can change its position depending on what is most comfortable for you.

Three-Speed Cooling Fan

Another feature that will ensure comfort when using this upright exercise bike is that it comes with a built-in cooling fan. You can choose from three available speeds.

30-pound Flywheel

Weighing 30 pounds, the flywheel is designed to offer smooth resistance. It will also help to make your exercises more challenging.

Built-in Speakers

Stay away from boring workouts! Spice it up by adding music to help keep you going. You will love how it comes with built-in speakers so you can listen to your favorite tunes as you enjoy cycling.

With all of these features, the price of Nautilus U618 Upright Exercise Bike should not be an issue. Click the button below and see why it is a top-rated product.


325-Pound Weight Capacity

Many of the exercise bikes in the market can support only 300 pounds of weight. With this model, on the other hand, you can use it even if you are up to 325 pounds without worrying that the frame will wobble.

The Good

Not convinced that the Nautilus U618 Upright Exercise Bike will make an exceptional choice? Here are some of the benefits that might make you change your mind.

Provides a Versatile Workout Experience

One of the best things about this product is that you will have a lot of choices when it comes to workouts. It has 29 customizable programs. You can choose which one is most suitable for your mood or goal. You will also love how it comes with 25 resistance levels, allowing you to adjust cycling intensity as preferred. However, if you would rather have one that offers unlimited resistance, then you are better off with the Assault AirBike Classic.

Bluetooth Connectivity

We also like how it offers wireless connectivity through Bluetooth. This is expected since it is a high-end model. The latter will let you connect the bike to compatible equipment, such as a smartphone and a fitness app. You can also connect telemetry tools for measuring your heart rate while you are cycling.

Comfortable Seat

Another good thing about this exercise bike is the design of the seat. This is unlike those that you will find in cheap models that are hard and uncomfortable. In this model, the seat comes with innovative gel cushioning. Your workout will be less painful and more comfortable, even if you will be cycling for a long time.

Compact Design

This powerful exercise equipment is also known for having a compact design. If you live in a small space, you will be happy with its size.

Allows Virtual Rides

If you want to take your home workout to the next level, then this exercise bike is a great choice. It is compatible with Ride Social App. The latter will connect you to other riders. You can also ride virtually. It incorporates an element of socialization in your exercise.

The Bad

The Nautilus U618 Upright Exercise Bike has some drawbacks, which might give you second thoughts in choosing this product.


The biggest issue with this product is the high price. Clearly, this isn’t marketed towards budget-conscious buyers. It is for those who do not mind going on a splurge in their search for a luxurious workout companion. If you are looking for a cheaper alternative, make sure to look at Marcy Upright Exercise Bike with Resistance ME-708.

No High-Resolution Display

Its LCD comes with a backlight, similar to what you will find at Nautilus U616. This is a good thing as you can easily see the information shown on the screen. However, for its price, you might expect something better, especially in terms of its resolution.

Short Labor Warranty

This exercise bike comes with a one-year labor warranty. This is quite short, especially considering its price. As a high-end product, the manufacturer should think of offering a more comprehensive labor warranty.

Who Is It For?

The Nautilus U618 Upright Exercise Bike is designed for people who do not mind how much they will be spending for home gym equipment. It is for you if you like multiple workout programs and resistance levels. This is also a great choice for those who live in tiny places as it comes with a space-efficient design.


In sum, the Nautilus U618 Upright Exercise Bike is a high-end product that can provide excellent value for every dollar. It is packed with plenty of amazing features and boasts of durable construction.
