Blue one seems to be a Bird Baja
but someone cut the original seat back
and front bumper (and replaced that with an ugly home made one)

The red one is a mystery.. it's soooo fricking close to a 225 Manco
(aka american express)
but the tube to stiffen the back rest against the rear bumper.... nope.
I've seen it around before but I have no idea what it really is yet I'm afraid
