The frame is a Panasonic DX-4000 with 700cm wheels. Checked the tube size - it's perfect for the motor mounts. Cr-Mo frame with double butted joints, and the frame size is 56cm. Should take quite nicely to a motor.
This isn't mine, but of another one I found online. Mine just needs tubes and tires and it'll be ready to go. Well, that and I have to get a straight handlebar. There were two weed whips on top of it, both are gone since I grabbed the bike yesterday.
