This is a 70cc 2 stroke BMX bike that was crafted via Frankensteining a 70cc Stihl 2 stroke motor with a BMX bike. This minibike / scooter / moped (or whatever you wanna call it) has a centrifugal clutch so it's automatic. I used to ride it everywhere in high school. It has been sitting since then, so it will need some work to get running again. Could be a fun father/son winter project.
