I know we all want to ride our own beloved bikes, but when I went a couple of years ago, taking my own bike wasn't an option for various reasons, so we all rented mountain bikes from a local shop. A hybrid would do fine. There are a lot of businesses there that cater to the Creeper Trail cyclists by renting bikes and hauling you up the mountain so all you do is ride down! Fun, fun, fun. Not challenging, but fun.
