I wanted that system but didn't want to spend the money on it, so I built something similar. It's a little embarrassing how long it took me to figure out just how to do it, but I've been using it for quite a while now and it's great.

I used conduit for the crossbars and put a roller in each end so they could roll forward and back on the rails. For the hooks, I bought aluminum straps, cut them into pieces, and bent them into hooks. Then I put some clear plastic tubing over the hooks and hung the bikes up. I can get 9 on there I think.
