Diamondback Fitness 910SR Seat Recumbent with Electronic Display and Quiet Magnetic Flywheel

My doctor suggested I get an exercise bike to use in addition to the treadmill I use. Had a knee replacement about 4 years ago and still have stiffness and swelling at times. I read all reviews both on Amazon and independent reviews on line. Diamondback was rated # 2 by an independent review ( # 1 was pretty pricey) . I chose a recumbent bike because my husband uses one at the gym and I wanted to have something he could use as well. Price went up while I was watching this item, then went back down so I decided to go for it. It was delivered by a trucking company exactly when they said they would. They even phoned to advise they would be at my home in about 30 minutes. And they were, they carried it ( large box, 2 men and a hand truck) into my home and placed it where I asked them to. I had also purchased the assembly option which was scheduled for the next day. My appointment was for 11- 2p.m. window, gentleman arrived at 4:30. Only took him about an hour to assemble ( he said it was a great bike). I have only had this for a little over a week. Happy with it, very solid bike, no noise at all when riding. Lots of programs to choose from, a great workout. If you hold your hands on side handles, heart rate appears on screen that tells you what zone you are in, warm up, cardio, fat burning etc. I do not know if it is totally accurate, I think you would have to wear a chest strap and use handles to see if they agree to rate accuracy. The bottle holder is located in front of you, I have used a standard Poland Spring water bottle with no problem. The fan does not produce much of a breeze but that is not what I really care about. I can pedal this bike ( with a stiff knee) in comfort and enjoy using the various programs to challenge myself. The seat is very comfortable, adjusts easily. I am 5' 2" and can reach the pedals, no problem. Bottom line, happy with the quality of this bike so far !

Short summary: the quality of the materials is good and the bike does feel solid, now that I can properly sit on the seat because it actually stays where I want it (a short story on that later). Also, the packaging was good. The 30-minute timer on the exercise programs and the lack of programmable options feel a bit limited.There were some shipping issues - the first carrier, Roadrunner, lost the bike at one of their shipping bays for nearly a month. Amazon sent me a replacement via another carrier. I am not deducting any stars for this, because it was carrier issue and not a manufacturer issue. However, there were definitely some manufacturing defects, which were not noticed until after I had unpacked this behemoth.I waited almost seven months before writing this review, because that is how long it took me to stop procrastinating on attempting to fix the various manufacturing defects. However, I wasn't the only one who procrastinated on attempting to fix this bike; after I engaged the manufacturer over the phone, it took about two weeks for them to actually ship the replacement parts to me. (Incidentally, the manufacturer is Diamondback Fitness, not to be confused with Diamondback Bicycles, which is a completely separate company. Diamondback Fitness seems to owned by the same company that owns LifeCORE Fitness, which makes the exercise equipment sold at Sears.)Four things were wrong with the recumbent bike and its attendant paraphernalia. For starters, the parts listed in the assembly instructions did not perfectly match the parts actually provided. However, with minimal thought, it became clear how the parts provided should actually be used and that the assembly instructions are likely out of date. Another minor problem was runs in the decals on the side of the bike; these are mostly unnoticeable though and I chose to leave them as is.After I had assembled the bike and had been using it for a couple of days, I noticed that the seat would not stay locked in position. I tightened various nuts and bolts on the seat slider assembly, but to no avail. I performed this process several times before I noticed that one of the bumpers on the slider was missing. The bumpers are used to prevent the seat from sliding too far and damaging the ends of the slider assembly. I thought that maybe the missing bumper was causing a misalignment in the assembly. I called Diamondback Fitness and they agreed to send me a new bumper. I also got advice about how a bent fork in the clutch box could cause the problem that I described. The representative claimed that I could take off the clutch box with the provided assembly tools. (This claim turned out to be false - I had to find an appropriate Allen wrench in another collection of them.) When I received my replacement "part" from the manufacturer, it turned out to be a replacement for the entire seat slider assembly, sans clutch box. Rather than replace the entire assembly, I tried to attach the missing bumper. That is when I discovered that the existing assembly is so badly misaligned that the screw holes don't line up enough to even insert the bumper screw. I could probably fix this by drilling out the outer screw hole some, but it is not worth the hassle.After living with the slipping seat track for another few months and having attempted to add the missing bumper, I became irritated enough to tackle the clutch box. That is when I discovered the most serious manufacturing defect. The clutch box is attached to the slider assembly by four bolts - only one of those bolts had a washer between the clutch box and the side of the slider. This caused the entire clutch box to be inserted on a slightly crooked angle. After digging up the appropriate hex key (not included with the assembly tools), I was able to remove the clutch box. Initially, I tried adding washers to three bolts which were missing them. However, this made the problem worse, because it caused the clutch forks to not catch in the teeth of the slider rail anymore. So, I then tried without any washers between the clutch box and the slider assembly and this fixed the problem by allowing the clutch fork to fully insert between the slider teeth. Apparently, someone in China thought it was okay to not add one of the bumpers in one place and then add an extra, unnecessary washer in another place. Shoddy manufacturing....

The bike was delivered early, within the scheduled window. We opted to not pay for assembly, but the assembly cost may be worth your time. My husband assembled the bike yesterday, and it wasn't difficult, just took over a hour, and a few instructions had to be deciphered.I have used recumbent bikes on and off for several years at the gym, and selected this one for the heavier fly wheel, after a month of doing my homework. The price is higher then the Schwinn, but this offers a sturdier and smoother ride. You get good resistance without the issues of a lighter wheel. If you've never compared fly wheel weights, do this before you purchase a recumbent exercise bike. There are technical comparisons online that describes why and that piece of information helped me choose.The display was easy for me to pick up, and I tried out several features right away. There are no issues so far. I was not looking for a bike with the large iPad type screen, it you want that, be sure to check the fly wheel weight. Those types of bells and whoIsles drum up the price, but your getting a different type of bike.Items that are very minor, the space to hold an iPad or phone on the top of the console, will not fit an iPad sideways. I knew this from looking online and it wasn't a deal breaker for me. I primarily listen to music while working out.The bike is narrow and long, feels stable and rides great. Seat is comfortable, it's mesh back is not a design I've seen in gyms, but the outer mesh zips off, so I am tempted to order a spare now.Special note, there is an optional water bottle made for this product. It's sold separately at the mfg. website. The water bottle holder has a distinctive design, and you think there may be a bottle included. So not a biggie.No problems with delivery, parts, or operation. We will update again in a month.

Received damage and missing part and told missing part was apparently lost. Returned a damaged package and now product the was incomplete and waiting for refund .
