This bike is VERY easy to set up; i never opened the instruction booklet. All tools are included with the purchase. I had this baby set up and running in about 35 to 40 minutes. It is relatively quiet for a chain driven bike; it does not squeal when you increase the tension.
The seat, however, took some adjusting to get it solid enough to hold my weight ( 155 lb male ). My only con is that the seat is too hard and after a good 45 min ride, my bum was sore. No problem, I can buy a new seat and easily interchange it.
For the price, this bike is a serious bargain. It's study and reliable. If you are looking for a good spin bike for a bargain, this is the way to go.
