Bought the E-bike Rack with Trike attachment 'cuz that's what we needed. Got a little concerned when I tried to lift the 2 boxes because they were HEAVY. Worried that the rack might be more than we two old folks could handle. But once we got it assembled we were pleasantly surprised at how easily it folds up and down on the back of the vehicle. It is still a heavy unit, but it rides well and no sloppiness in the fit. Very well built and have no concerns about it being able to carry the weight. Our only semi-negative is that when it says it takes 2 people to load the bike/trike, you aren't kidding. It's quite a "heft" for us...but then we are both in our late 70's now and lifting isn't quite the piece of cake it used to be.
