Nautilus - U618 Upright Exercise Bike - Black

Great to have a bike like this which is very quiet and feels like you can build momentum when you pedal. Like bikes at the gym, the different settings seamlessly change difficulty. Nautilus has good support if you run into any issues during assembly and the assembly instructions are clear. I like that there are wheels in front if you need to move it. Only things I think could be improved: seat is a little hard even with 'gel cushion' and seat should have option to move it a little closer to the handlbars for times you want to sit up straighter.

I waited to review this till I’d had it a month or so. I read reviews with interest before I bought, and was a bit worried as a few talked about the seat being uncomfortable. When your body has a small little…ummm…seat contact area like I do, that’s not good news. I don’t find the seat uncomfortable at all. It adjusts for tilt, height and fore/aft. I would say people just haven’t adjusted it right. I also read a few who said there is no way to tighten the seat so it doesn’t wobble. I would guess that’s because people missed the fact that after adjusting the seat position fore/aft, you have to hand tighten the plunger. Then its solid. Directions? Better than Ikea, but not great. Probably not good enough for someone who’s never changed their own oil, but OK for the rest of us. Bike works well. Pedaling is smooth and quiet. Electronics are a bit crude, but once you get used to it, who cares? I use the little heart rate sensor you put on your chest, and love the adjustable little fan that blows on you. I have no conmplaints that matter, this is a good bike.

This is a very sturdy, well designed exercise bike. It is near gym-quality, not a typical lightweight “home gym” purchase. The display and interface is of high quality but not what you might expect from a contemporary product. It is a monochrome character display, not a high definition (or even low definition!) video display. In this way it is at least one or two generations behind other popular machines such as those made by Pelotor or NordicTrac. On the other hand, it costs only about a third of what they do! The display console angle can be slightly adjusted, but on mine it want to stay in one of two positions—either fully upright or all the way back—I am not able to place it anywhere in between. Using the app along with it does add some variety to the workout. I’ve only tried the few free tours—you have to buy a subscription to get access to the rest—and they give you high res video to go along with your work out. The video tracks fairly well—it speeds up and slowed down when you do—but it is NOT an interactive workout, it’s just a way to give you some outside scenery to look at while exercising inside. Quite delightful really, especially if your bike is in a room with a nice TV! The saddle is very well padded, with quick-adjustments for both up and down as well as fore and aft. Most people should be able to find a comfortable position. The pedals have toe cages and are of good quality. There are two sets of handlebars—one straight set positioned just under the console for cruisers who prefer sitting upright in the saddle, the other far out in front for those who like a more nearly prone position. The position of each is somewhat adjustable with a wrench, but there are no quick releases for easy changes. Overall you can get a very good workout in this bike. If you want to spend the $2k on the more modern setups, or if you think you need the HD display and interactivity to keep you motivated, I’d say go for it. But if you are looking for a solid gym-quality machine to give you a challenging workout and only have only $700 to spend, this should meet your needs.

Delivery was Great. I had the unit assembled in a short time and the price was very reasonable. Prior to the purchase I read alot of reviews. So far I've had no issues. Some made coments on the flywheel ans seat. With the ability to adjust the resistance level on the pedals is fine for me. The comments about the padded seat i dont see an issue, when was the last time you were actually on a 10 speed bike, remember how hard those plastic seats were? I am satisfied with my choice of purchasing this unit.

I purchased this on sale and so far it is well worth the money. This is a good model that bridges economy bikes with the high end gym models. Nautilus seems to be good quality, but the only issue I really have is with the seat. It takes a lot to ensure it is secure and won't turn.

Nice exercise bike. Has all the bells and whistles. Only thing its a bit to big for me. I adjusted it to the smallest settings and I just can't get comfortable riding it. I'm 5'4 and 140lbs for reference. I think it would be great for a larger man.

uncomfortable seat after 30 minutes or so. Love the bluetooth connectivity, it saves your workouts and even puts them into the workouts area of the Apple Watch. Metal is sturdy, everything fits well, robust product. The seat is easily adjustable up and down, backwards and forwards, but some additional squishiness would be appreciated as it can hurt your "sit bone" until you get used to it. Everything screams high quality with the bike and I don't think anyone would be disappointed, just get a nice padded towel to sit on until you get used to it.

I am very happy with the bike. I can choose a track and a speed. Easy to adjust to my height.
