Hate to say it but my bias goes way back to jr high and before ( mid-late 60's ) we called them pu$$y bikes ( because that's who rode them back then ), we had to have a REAL " fat tire" StingRay and have had a few people REALLY mad at me for saying that, even had a guy want to fight at a swap after I said I don't have any parts for pussy bikes ( it was really early in the morning and was unloading and I guess I just blurted it out and didn't even realise he was so upset till a fellow caber told me ) so sorry if your offended but that's just a historical fact for me, that's what they were called growing up, so next time I'll be more politically correct and say "sissy bikes" , after all who makes a dirt bike or chopper out of a fastback? ( opinions expressed do not reflect on this site or anything else but just a 12 yr olds opinion! ) so I hope nobody want's to beat me up next time we meet!. Sorry this doesent address your value question.
