Very easy to assemble and lightweight. I was a little reluctant because the two bikes do have a little bit of weight to them so it had to be sturdy enough to support them. This was not a problem and it held up perfectly. The only downside to the whole thing was the adjustment of the bike holders. It was took some trial and error to get them to fit together. The picture looks nice but the reality is we ended up end for ending the bikes so there was enough room for them to sit over each other. They face in opposite directions. No problem in the long and short of it as the rack is functioning the way we wanted it to. By allowing us to keep the bikes upright and stacked we've gained more floor space. Win win.
