I read through SO many reviews on different stationary bikes through Amazon. I came across this and saw the videos and reviews of people mostly praising it, but others complaining about it being noisy and the seat being uncomfortable. I decided to buy it, the price was good and if it really was that bad then I'd just return it. When I got it, the instructions were SUPER EASY! Took me 30 mins to build it, could take longer if you really wanna take your time though. Tried it out and it's not noisy at all; it's super quiet and it feels sturdy. The seat is not uncomfortable, so I'm not sure what the other reviewers were complaining about. In all honesty, the only drawback is that at its highest resistance, it's not that challenging. However, I feel that I got a good 30 min workout and is exactly what I needed to add to my home gym. I love that it folds and doesn't take up much space. Definitely happy with my purchase and recommend it to anyone looking to get a good cardio workout. If you are incredibly fit and do lots of biking then this might not be for you (the resistance drawback mentioned above). I'm happy with it and looking forward to losing some weight.
