Terrible product. The magnetic resistance mechanism froze up and stopped moving suddenly after four months of use between the easiest and second-easiest levels. I ignored the negative reviews when I bought it, hoping I would get one of the better ones since it appeared ideal for small-space living, but now I am out 139.99 since it's too late to return this defective bike. I don't usually write reviews but this bike is so bad that I need to warn any prospective purchaser: stay away.
