Nautilus U514 Upright Exercise Bike Product Description

The Nautilus U514 is an exercise bike designed for home gym use.  It contains adjustable resistance levels, heart rate monitor, and customizable workouts based on resistance or heart rate.


  • 16 Resistance levels
  • Customizable resistance programs
  • Heart Rate Monitor
  • Bottle holder
  • Adjustable handle bars / seat

  • Longer Warranty


  • Quality of bike
  • Not for tall people, legs hit handle bars

The Nautilus U514 offers adjustable resistances from 1 to 16.  Like the similar Schwinn 150, the Nautilus U514 offers customizable workout programs, where you can do intervals based on resistance or heart rate.  Example, first 5 minutes lvl 5, next 2 minutes lvl 12, next 2 minutes, lvl 8, next 5 minutes lvl 5, etc. Or you can set target heart rate zones and the system will adjust based on your current heart rate.

The Nautilus U514 is made by the same company that makes the Schwinn exercise bikes.  It is comparable to the higher end home exercise bikes; the Schwinn 140 and the Schwinn 150.

Some users of the Nautilus exercise bike complain that their knees hit the handle bars.  One user recommended that anyone over 5’9″ should purchase a different bike, because even their knees occasionally hit the handle bars.

The Nautilus U514 contains wheels to move the bike around from room to room, although, it does not wheel that well on carpet.

Who Should Purchase the Nautilus U514 upright exercise bike? 

The Nautilus U514 is a decent quality exercise bike.  It is very similar to the Schwinn 150 in quality, features, and price.  Unfortunately, the Schwinn 150 offers a few more features, like the speakers and MP3 connector and it comes at a similar price.

When compared to the Schwinn, the advantage of the Nautilus exercise bike, is that you get a longer warranty on all of the features; parts, frame, wear, electrical…Which I must say, is a nice feature to have.  But worth the money? That is up to you.

  4. Customer review from the Amazon Vine™ Program () I have the Schwinn 430 epicltilal, which in my opinion, was the best epicltilal in its class for under $1000. It has an 18 stride that works for most people. There is now a new successor in home fitness equipment. This is it! Whenever someone thinks outside of the box and creates a new machine to appeal to more people, they create a winning product that will set the standard. Schwinn/Nautilus and their engineers/experts have done it with the Schwinn 460 Variable Strike Elliptical Trainer. How is this different? Without making any adjustments in the machine itself, you can vary your stride from 2 inches to 26 inches. This translates to anyone in your family (of adolescent to adult age) to exercise on this piece of fitness equipment without cumbersome settings or having to get off of the machine to make adjustments. When it comes to epicltilal trainers, you really need to try the various strides to see what is comfortable to you. Some are circular and some are truly epicltilal in feel. With Variable Stride Technology, this is less of an issue and I feel this is going to be comfortable for everyone who enjoys using this method of cardiac activity. Variable stride technology involves changing the length of stride based upon the pressure that you exert on the pedals the more pressure you exert, the longer your stride, the less pressure, the shorter your stride. This is something that will take some time to get accustomed to but it doesn’t take that long once you get the hang of it. This machine can accommodate people up to 300 lbs. I weigh about 200 lbs and it’s very comfortable and stable. Basics: The dimensions are 54 L x 34 W x 73 H where as the 430 s dimensions were 59 L x 26 W x 68 H. The machine is 5 inches taller in total height than my Schwinn 430 (and the pedals are about 3 inches higher from the floor) which may be a little difficult for people under 5 feet tall, but it is manageable. There are 3 hand settings, the moving swing arms, the stationary handles with heart rate capability and the stationary handles more forward in position without heart rate capability. However, there is an integrated wireless heart rate monitor capability utilizing a strap across the chest. The strap is more responsive to your heart rate over the stationary handles. Set up: My model came with prepackaged hardware with all of the tools necessary to assemble except for a 17 mm wrench. I opted to check the sizes of the various hardware and used a ratchet and my own screwdriver. Although it took about 20 minutes to get it out of the box, when you get into the assembly time, it only took a little over an hour. Luckily extra parts were included since some were missing in the prepacked bubble wrap’. I didn’t get operating instructions so I had to refer to the website to get the manual. The assembly guide is outlined well and easy to follow step by step. It recommends using 2 people, at times (placing the base and the pedals, for example), but I was alone when I put it together. If you do the assembly by yourself, just watch your fingers when you are putting the pedals together. My suggestion is to bypass the included tools and use your own toolbox. However, I do not recommend electric screwdrivers or other devices with high torque which would strip the screws and probably damage the unit. Construction: The machine is solid steel in construction. It is higher grade steel than the 430 with a gray matte finish. It is not textured like the super expensive gym equipment. The length is about the same as the 430, albeit slightly wider. The pedals are solid in construction, rubber coated/slip resistant and the action of the stride is smooth and quiet you can watch television at a normal volume unlike other epicltilal trainers and treadmills. The handles are comfortable, rubber coated and have an ergonomic design in any of the 3 standard hand positions. It is markedly taller in height than the 430, also. Electronics: The unit comes with a back-lit, touch screen that is intuitive, easy to read, and shows your progress in calories, distance, time (interval and total time), pulse, speed, calories, and level. The LED text is clear and easy to read. You have manual mode and 16 programs but in your profile, you can create 2 customizable workouts one interval at a time. I miss the Calorie Goal feature (i.e. pre-set workout to burn 500 calories). The customizable feature keeps track of your progress over time: total distance, change in weight, total calories, time spent, etc. Depending

  5. the handle comes attheacd to it, it is not removeable. and the swivel wheel is suposed to come with it, BUT from reviews i have read on sometimes it gets shaky, but one review explains how to fix it by taking the wheel off and tightning the bolt that goes up towards the swivel. I plan on checking the tightness before i even use it to avoid the problem all together. i would recommend sewing velcro on the parent console wrap around handle bar to avoid it being lost 2.
