They really are nice racks. They have a bit too much bass for my taste but that can be fixed with equalizing and I bet some people would like it. The only way I can get pain free travel out of these is if I loosen them to the point they?re just flopping around on my foot. My five year old loved them. Overall it works well but unfortunately does not have a great locking mechanism to lock the bikes on the rack. I love this thing, it really stands out, too. I do a lot of walking and hate closed in shoes but find it difficult to get shoes/sandals to fit as I have a wide foot. My feet were sore, red, and blistered after wearing them just 6 hours. Great for a home gym! No talk of securing the apparatus to a joist.
