Delivery arrived in one rather heavy box. Took 20 minutes just to unpack and remove protective foam from all parts, which was OK because things were packed tightly together and all the padding helped. While I had assembled many bikes in my younger life, I haven't assembled a bike in over 25 years. I found the included instruction book and video on assembly on the Amazon site differ a bit from the actual fitment, parts, and tools needed for assembly. All that said it took this 70 year old about 3.5 hours of puzzling it out to put this bike together. Out of the box there was one missing part and one broken cable, but Pacific Cycle (who owns the Schwinn name and manufactures the bikes) Customer Service quickly supplied replacements within a week. Bottom line is my wife (73 years young, 5'4" tall) LOVES riding this 26" bike (this three speed version is perfect for her), and that's what this purchase was all about! If you have previous experience assembling bikes I believe you could handle putting this together, but if not I would recommend contacting a knowledgeable friend or a bike shop for assistance.
Overall my wife and I would recommend this bike, but with the foregoing caveats.
