There are moments where you make decisions, but most of your decisions feel without consequences. The little pads the bikes rest on can slide off the bars pretty easily when the kids try to pull the bikes off. This shelf is so cute! The base of the mount was flexible, and there was no way to install it tight enough without deforming the base. For me it worked fine. Bought it as a gag gift for a friend. Its got some weight to it. I was skeptical with some of the reviews but I figured I would try it for myself! After a month or so of using it, the velro strap started to loosen which I feared would happen. The insoles provide wonderful cushioning and comfort.
