http://americanhiking.org/ They have a very comprehensive list of trails.

HE, I think it is more road walking than biking. I know the Cumberland Trail in Tenn is part of it and The Pine Mountain trail in Ky is also part of it. I don't think you can take bikes on them. Taking a road bike would be a pain pushing it up and over the mountains
Is this the one? (image is from: GORP - Thru-Hiker's Guide to America - Mountains-to-Sea Map, Gorp.com)
there was at guy at SoRuck who had hiked all of the MTS trail and per the map above it does start at Clingmans Dome. Not sure I would want to ride a bikedown it either. It might be kind of bbbbbuuummmmpppyyyyy
Almost the entire section East of Boone is on roads, though. I wouldn't want to walk that for sure - it'd be incredibly boring. Part of the MTS actually comes through here (Greensboro) and follows a paved "Greenway." In other words, IMO, the only section actually worth hiking is West of Boone.
