Nautilus U618 Upright Exercise Bike with Bluetooth Connectivity and 25 Levels of Resistance

A great mid range exercise bike if you are looking to get into shape, not run a marathon or Ironman events. For my needs it is perfect. Seat is very comfortable. Easy to set up the bike. Only needed a 2nd person for a couple of things. Otherwise 1 person can do the majority of the set up.

So far I love this bike. I'm partially blind so I'm having a little trouble reading the manual to get things set up. My phone sees the bike for pairing as B618 instead of U618. unsure why. Also you should know before purchasing that the Nautilus Trainer app that's mentioned and is mentioned in the manual is no longer available. I'm looking forward to using this bike daily. I'm more or less isolated due to COVID-19 and have gotten out of shape. This bike will help get back in shape. I'll write another review once I've use it a few months.

This a a great exercise bike with pre-programmed workout routines. It is very sturdy and extremely comfortable to ride. It is loaded with features. This bike can last for a lifetime, it can support a person weighing 350 lbs.

Just what I was looking for in an upright bike

Great bike for the price. Walmart price was substantially cheaper than I could find anywhere else. Bike rides smooth. The only downside is that although the bike had the premium seat I still find it a bit uncomfortable, perhaps it will soften up with more use. Definitely would purchase again!

Try to maintain a daily routine. Starting at 15 minutes with a goal of 30 minutes by the first of the year. My Cardiologist and Primary care doctor are both excited that I got this bike. I can tell that it is going to take some getting used to but I am pushing myself to reach my goals.

I like this bike alot. So why did I only give it 4 out of 5 stars? See below. There are many positives: Assembly instructions were clear (except for location of the serial number); it took me about 90 minutes to set it up. The machine is heavy-duty and stable (apparently the flywheel had a substantial upgrade from the prior model). It's easy to use. The electronics are basic but, hey, it's an exercise bike, not a lifestyle! The graphics take me back to computers of the 90s, but that's okay--the bike conveys all the information you need. There are several pre-programmed workouts that span the gamut from easy to I-can't-even-start-that. There is also the capability of creating your own custom program and saving it. You can set up different user accounts to store your data--handy if other family members will use it. Now the con: The heart rate monitor over-reads my heart rate by 20-30 beats per minute, particularly at high pulse rates. This is really a bummer because I am gearing my workouts to the CDC/WHO/AHA guidelines for vigorous physical activity which is based on sustaining your heart rate at a certain level for a certain time. This is true both of the (easy to use) handlebar sensors and the (not-so-easy to use) chest strap. I called the help line and the woman was very helpful, but couldn't help. She said the sensors have a tendency to "spike" when first recording, so I should peddle and hold the sensor for 2-3 minutes before believing the number. It didn't make a difference. So I live with it and do the mental math for my heart rate. So there you have it: a very solid bike with rudimentary but adequate display. It is easy to use and has a wide range of programs. The heart rate monitor is the only glitch. And the price is quite reasonable.
