Over All Rating Reviews : 
Reviews on this item looked great, so I decided to try it. The outcome? I am disappointed, though the product is tolerable considering the price. The biggest problem is that the machine is not stable--when I bike on it, it moves around following my feet movement. So I have to put my hands on it to keep it in place and get some excercise. If I raise the resistance level, it becomes almost unusable because of the movement. (Maybe this is more so because I have hardwood flooring at home, and it might not move as much on a carpet. I could not try, since on my rather small carpet, the machine moved WITH the carpet. If you reduce the resistance level, it does not move around too bad--just up and down a bit with my feet.) In addition, the pedal is not that well made, feeling heavy and making small sound.
Well, considering the price, I thought I could reduce the resistance level and tolerate the annoying movement and uncomfortable feeling of the pedals. But I found that I am not using it after a few tries, mostly due to the inconvenience. I simply cannot enjoy it. So I am returning it.
I do not recommend this product. Especially if you want some real exercise, consider other options. But if you are ok with slow pedaling at a low resistance level, you might not have much complaint.
I am not happy b/c the shipping cost will be quite high, given the product weight. The service representative wasn't very kind either, though again, tolerable.
