It looks like a great bike.
An informed buyer is going to see these key points:
- No warranty support.
- Amateur built.
- Wire ties and lose, sagging cables.
- No knowledge of how it was treated.
- It is used, not new.
- A professionally built, warrantied bike can be purchased for less than your build cost.
- Used battery is essentially worthless.
But they will also see these points in it's favor:
- It appears to be a Lunacycle kit.
- It's shiny and blue.
Things that will help it sell:
- Fix the cables so they look like they came that way from the factory. No sags, no visible cable tie ends. cable tie use should be artistic, and not detract from the look of the bike.
- Clean it and wax it, then display it in an aesthetically pleasing location for your sales pics.
