For reference: I am a 49 year old, 6'2", 270 lb man. Reasonably in shape, though carrying a lot of weight in my midsection.
Things to know about this bike:
- Very quiet.
- Works well with the free app for tracking workouts, personal bests, etc.
- Numerous different pre-set workout programs from easy to extremely challenging.
- Nice large display that's easy to see, with large, tactile buttons, including big tabs to increase or decrease intensity as you ride - these tabs stand out clearly and are placed on both sides of the console. My only complaint about the console is that it's so big that I have to have the bike pointed at an angle to my television in order to see the TV as I ride - not a problem, but stood out to me enough that I feel it's worth mentioning. Very minor, personal issue.
- Solid, firm construction. No rocking or wobbling.
- Was relatively easily assembled by myself, but please note, I usually have a knack for building things that require assembly - for a smaller person or someone with less strength, I would recommend enlisting 1 other person to assist with assembly.
- Smooth pedals.
- Quiet wheel with very responsive and strong magnetic tension.
- The seat is actually very good quality and well-padded, though pretty firm, and nice and wide. I've ridden for an hour at a time on several occasions, and the seat doesn't completely numb my groin like some exercise bike seats have. I would recommend waiting to decide to buy an additional seat pad, but you may still want one.
- The little shelf on the display is big enough to hold 2 smallish TV remotes, or 2 cell phones, or a tablet. If you put something on the shelf, you're likely to cover most of the readout, but there is still a small part of the display underneath the shelf that shows a countdown timer and some other info.
- On the display there is even a very small fan (small and weak enough to be nearly useless), and blue-tooth connected speakers (which I haven't bothered to try out).
All told, this bike is very solid, and has a lot of nice features that I would never have anticipated in its price range. It was deeply discounted because the next year's model was out. I compared features between the two, and could find nothing that the newer model has that this one doesn't other than some different colors and other minor cosmetic differences. Interestingly, the side-by-side comparison I found suggests that the newer model has the Bluetooth connectivity, but this one doesn't, when in fact, this one does as well.
Increasing rating to 4 stars now that it seems to be working. I finally got around to replacing the inlet. I'm not a mechanic, so I don't own a socket wrench set, which is required to replace the power inlet. Socket wrench sets are more expensive than I was anticipating, but I guess I should have them around anyway. I had to disassemble the body of the bike (which came pre-assembled). It was super involved. Needed to remove a lot of attachments to be able to remove the side panel (shroud). The whole deal took me about 45 minutes. Once everything was open, it was just a matter of disconnecting the power inlet from the internal wiring and replacing it with the new one...then reassembly. Thankfully, everything seems to be working now, no power failures so-far. Crossing my fingers.
Called Nautica/Bowflex to explain the adaptor problem, they were very nice and set up a warrantee claim for a new power adaptor, power inlet, and crank puller (tool to remove pedal arms). They asked me to send my proof of purchase so they can ship the items. I sent the proof of purchase and they sent the crank puller within a couple of days (took 5 more days to arrive), never shipped the actual adaptor and inlet. I called back and they said they could not ship them because they did not receive my proof of purchase (even though I received an email that acknowledges receipt of the proof, and the crank puller had already shipped), re-sent the proof of purchase and received the remaining parts in another 5 days. I first just switched the adaptor to see if that was the problem, but the power kept shutting off, so I know I have to replace the inlet, which requires disassembly. I retrieved the crank puller sent to me by nautica, pulled out the instructions and found out that I need additional tools that I do not own. Guess I'm getting a new set of tools. For now, the electrical tape seems to be working ok, I'll update when I get around to replacing the inlet.
The bike is pretty sturdy (I'm 6'3" 250lbs and this holds up well during intense workouts). The seat is plenty tall and can even go a few inches taller if I needed it. The display is bright with lots of data. Nice features like goal tracker and workout selection (my favorite right now is pike's peak). Pretty easy to put together - took me about 45 minutes by myself. I don't use the speakers, they aren't very good (as you might expect). Heart monitor is a little glitchy as it continues to "read" my heart rate even after I've removed my hands (which kind of screws up the goal tracker), when I am gripping the sensors, the heart monitor does seem accurate, though the accuracy seems to be decreasing the more I use it. HOWEVER! The adaptor or input doesn't work properly. It sometimes comes loose and the bike will turn off in the middle of a workout. When I'm 29 minutes in at a resistance level of 10 and the power just shuts off, it's really disruptive. I have to get off the bike, readjust the adaptor and get back on. Also, when it does that, none of my progress gets saved. I've taped the adaptor/input with about a half roll of electrical tape...we'll see what happens. I'm sure if I call nautilus, they'll have a solution, I would just rather it work correctly in the first place.
