DYI scooter M&M relax mashine

Good day,
well it been quite a while I had thoughts to built my own two wheel something and not long ago I sold my Chinese mass production small wheel 1600w scooter so now I got room for new one. There was things I liked about my old scooter and there was some I wanted to change. Therefore I'll build according my needs, which are:

- front wheel size about 26inch
- end 17iinch motor wheel
- long swing arm
- extremely diy plush seat from lots of good quality foam
- medium or long travel swing arm
- lipo battery 66.6v 20mah or 44v 40mah or this and that
- mxus 3000w v3
- wooden feet rest deck

Today I looked for a pipes but finally found some thin pipe in my basement. Bearings removed from my old skateboard.
