Looks like a neat little board. I don’t think you’ll be able to sell all parts individually for that much (as in, something will remain unsold), so if I were you I’d try selling locally; make a post for it on whatever used item selling website you have where you live. GLWTS
The FSESC and motor should be the easiest things I could sell. Drive Train is fully custom made out of alunimium and can be upgraded to a 15 mm Belt, but unfortunately no 6374 motor. Because technically the motor plate can take a 63mm motor, but it’s the plate, which is too short. New price was nearly 600.
I sell this because I go full e-mtb.
As it remains DIY, it could be tweaked here and there. It has nearly 200 km on the clock. @rusins In Germany it’s called Ebay Kleinanzeigen(classifieds). I’ll give it a shot and if nothin’ happens there, I’ll sell as much parts as I can.
