I had this on Craigslist bikes and received a lot of responses offering cash, and after the fifth person flaking, I can remember why I didn't bother selling when my kids outgrew it.
Hopefully, someone with similar hobbies and who enjoys bartering as much as I do will take an interest.
Things I would be interested in:
The child who once rode this bike now plays piano and would like to have the option to play NI Komplete from a keyboard.
I always wanted a shreddy 7-string guitar
I need a new speaker cab or guitar speakers
electric drumset
guitar FX pedals.
