I had a similar bike that is heavier purchased for about the same price. This bike keeps moving from side to side and then the bike becomes stuck and you have to continually rewind to then reuse! Very disappointed don't buy this product buy one that is heavier in weight.
I bought this to keep my legs fit as I am going in for total hip replacement-both of them. I found the pedals to be only average as I can't seem to tighten them up to give me a good work out. But at least I can do something after surgery. Not enough resistance.
