  1. Heather Romo

    Good for the priceGood simple bike, gets the job done. Not super sturdy and my back hurts when I use it, but I think it’s a great buy for the price point.

  5. Gwen Ryan

    Fine fitness bikeEasy assembly, light enough to relocate easily but is still sturdy, comfortable to ride and has a large font on the screen to view/track progress.

    Good for the price – pleasantly surprisedAssembly took about an hour and 15 minutes. Easy to assemble. I had one issue, the very last step. Inserting the handle bar into the slots…one of the slots was damaged and bent in…luckily Was able to use a pair of pliers to open it enough to get the handlebar in. I was not interested in repacking and returning, so that worked out. Did a 40 minute workout today…worked up a good sweat ….cheap info tablet is included, but it works fine. I weigh in at 190 or so…was relatively comfortable. It’s not gym quality by any means, but its not going to be used all day, every day. so for now, I am happy with the purchase, and I recommend it if your budget is not in the Peloton stratosphere.. If things go bad in the coming weeks, I’ll report back.It’s now September 2, I bought the bike in early July. I have worked out on the bike nearly every day..typically 35-45 minutes. .I will say I am very pleased with how it has worked out…My gym is closed, but will reopen later this month. I really have no desire to go back. I am able to get a great sweat with this bike. I can get my heart up to 120 or a little more if I desire. At first, I didn’t bother with the cables connected to handles. But I figured out how to tighten the cable and I do butterifles and shoulder presses while riding. It’s a good simple upper body workout. I do other light lifting and also purchased Battle Ropes from Amazon, which are great. I had some reservations about the display, but it’s very accurate, you can reset it every day, but the total miles rode keeps accumulating. I like that.So..I would recommend this affordable bike. I intend to keep using it.

    Basically functional, but not for tall peopleThis bike does what it says it will: it pedals, with variable resistance settings; it can be set in different positions (recumbent, upright, and one in between); it folds up for easy storage; it has resistance bands for a little extra workout; it has a computer for tracking workout details, as well as a pulse monitor. It is also pretty easy to assemble, despite the instructions being in Italian.However, it lost one star right off the bat when I finished setting it up, and found that even the tallest setting is too short. I’m 5’9 with a 32″ inseam, so not super tall. If I sit on a folded bath towel, I can get decent leg extension, but have to be mindful of my knees while pedaling in the upright position, or else they hit the handlebars. In the recumbent position, with the folded towel and pushing as far back in the seat as possible, it’s passable, but not great. Also, in the upright position, it’s hard as a tall person to find a really comfortable position for my arms. The resistance is decent, but not terribly challenging for an athletic person.It lost the second star during my first workout, when I realized that the tracking metrics are all off. I was also tracking on my watch, which is reliable. The pulse monitors always measure quite a bit lower than my actual pulse. The calorie tracker is very optimistic (reports roughly 3 times the amount as my watch), but this isn’t that surprising since it isn’t designed to take age/height/weight into account. Most frustrating, though, is that even the time tracker is off, getting about 10 seconds ahead of my watch for every 10 minutes of exercise–not huge, but seriously?!? I have no way of knowing how accurate the distance and speed tracking is, but these details are less important to me.I got this bike thinking that the slightly higher price point would bring with it more reliable quality than those in the $100 price range. Unfortunately, this has not been my experience. I can still get a decent workout, which was my basic goal, but am overall pretty underwhelmed with the product. On the upside, my 8-year-old has enjoyed using it:)

    QualityThis is my second Fitnation bike. I have one in my home in Michigan with 5000 miles on it. I have calculated mileage to Florida and completed that ride. I started on my next ride to Phoenix. We decided to spend several months in Florida so I ordered a second bike to ride while there. I have 110 miles on it. I have had no problem with either bike. I am 76 years old with arthritis in both knees. The bike is easy on the knees.

    Decent bike but not very comfortableThis bike was fairly easy to assemble and doesn’t take up a ton of room. Like that it folds up. Like that it has different measurements and has pulls for arm exercises.Downside is that the seat is uncomfortable. Not big enough for a larger person. Arm holders too lose to sides and rubs some. Seat it self uncomfortable. Really like that it has a back but it needs to be much larger and provide a roomy area. It was supposed to be good for people much larger than me but I can’t imagine how that can be
