Question: Is there any warranty?
Document: I would  have purchased a warranty with it, if I knew one of the pedals would melt off! I had it for about 18 months, using it perhaps once, at most twice a week for 30 minutes each time. the last time I used it, one of the medals just clean melted off of the frame.
I used this product three times, about 20 minutes each, before the right peddle slipped off the metal arm. Something inside where they connect was broken. The product is unrepairable. Apparently Amazon won't refund me, neither will the manufacturer (though I did register the product for warranty). I would recommend purchasing something else. This is the definition of poor quality! It also makes noise and slides on the carpet. Fortunately, it never overheated on me.
you get what you pay for. uneven pedaling motion. cheaply manufactured. will not last. not worth one dollar. save your money for something better
works and function is less then lasting tension not up to my need in keeping fitness level someone who uses less then me would like
while recovering from a bike accident, my PT giver suggested the inexpensive and highly efficient InStride Cycle as a way to get continued exercise for my legs. I was highly pleased with the device. It was easy to put together, is quite sturdy, and meets my needs.
very good i enjoy it while watching my favorite programs. It is very easy to take with you any place you go.
this was very simple to assemble and works very well; the item is very sturdy. Would recommend for any one to use.
this was a great way for me to add a little more exercise to my day until the left pedal stripped and fell off. Now it is a waste of space and useless. I bought this in Oct and the pedal fell off in Jan.  Not a good use of my money. Very disappointed
this thing not so great, it gets to hot you can burn your fingers if you try to adjust position, overall not good workout, cant fit under any bed foot not stedy, whole unit not steady....
this prevents the rubber feet to rotate around the metal.
Answer: yes
