Okay, I was a bit intimidated when I took this baby out of the box.. but, I put it together. It was time consuming, but, that's because I am not all that mechanically inclined and I had the "help" of my two sons, ages 7 & 12. Afte we got it together I tightened everything up and all looks great. Looking forward to starting my exercise routine with this stationary bike. It is lightweight and compact which is a plus. I would recommend this product.
