second- brush of the rust

fourth- search for parts (this is still taking along time)
fifth- battery tray/ motor mount welding
sixth- missing brake parts-possible disc conversion
seventh- rear sprocket and chain assembly(not needed)

great ride.
The motorcycle mechanic told me it was a Chinese motorcycle

everything else worked. I wanted to learn more about EV
systems and hope to gain a small insight with this scooter
