After taking off everyhting I need, I put all the small parts in plastic bags and lable them. At last, put everyhting into a plastic box for easy organize.
This is my first instructable, which serve as a practice for me. I will post the instructable for building my version of electric mountain.
Thats give credic for the guy who come out the idea of electric mountainboard>>https://www.instructables.com/id/Electric-Mountain-Board/
I will use another method to mount the motor and controller directelly on to the axe so the motor will always in-line with the wheel sprocket. But also will not hurt the mountainboard. (means no welding, screwing, or superglueing on the board.)
Thanks for watching.
