I read numerous reviews on this product before buying and it was simple to assemble. The bad part...the knob that makes the pedals go up and down was impossible to turn. It never went in all the way and the pedals never went up. It looks as if something is jammed inside the hole and turning the knob is not enough to push the metal rod that forces the pedals up. I picked this up today and will return it tomorrow. Incredibly disappointed and really mad that I wasted my 50 bucks on this piece of crap.
Maybe it's my age but I have to be careful about my balance because there nothing to hold onto. It's a trade off to space consideration in my small apartment. I can live with it.
the left pedal did not work properly. I returned the item.
