just got this, i was planning to put an engine on it, but i was looking on ebay to try and find out how much it's worth, it's a ross mt. rushmore, i couldn't find an exact match on ebay but i did find other ross mountain bikes (mt. whitney,bear mountain, mt. mckinnley, mt. hood) the prices on those were from $350 to $14,000 (<- that's not a typo...$14,000!!!! really?) so i would really like to know what it's worth before i chop it up to motorized it. i don't mind chopping up a $200 bike but i'd hate to chop up a $1000 bike anyone know what it's worth?
