In Step bicycle baby or child trailer.
This connects to your bicycle and pulls behind with your kid or whatever in it.
It works great, fairly new needs nothing, very safe.
It cost me $130 new.
Knock $100 off that, first $30 takes it.
Price is firm no games ok, $30 isn't worth any aggravation for me, I just can't bare to throw it away and have someone take it from my curb then sell it to you for like $60 or whatever.
