Had this qt50 frame laying around forver and kept looking at the curve of it thinking i wonder what a hobbit subframe would look like on there. Basically i extended the (seat post) area up to give it a taller feel and to accomodate the cross bar for a top tank eventually. The engine mounts on the qt50 were already set back like when people stretch the hobbit frames so i left it alone. Chopped the head tube to fit pitbike forks and dis brake setup. Still a work in progress.
