I will say it took me about 3 hrs to put together by myself. I’m pretty good at putting things together, but this had lots of parts and I needed more room than I thought to work with. Fortunately, everything was very well packaged and easy to figure out. I was quite impressed with how well it was wrapped. This thing is solid! It is so much easier for me to load my bike on than the rack I use to have. I have (2) 49lb e-bikes and it carries them, no problem. My ONLY issue is the rubber coating on the hook that holds the frame in place, rubbed off during first use and scratched up the paint on my new bike. I would highly recommend using a floatie or pipe wrap to cover your frame and protect it from the hook scratching it up.
