What is the deal with these things, The large ones with the 26" front wheel and fat back tire. I bought one at an auction a few weeks ago and have been congratulated every time I see someone that was at the auction, I paid $100. for it, which I think was $50. too much. I bought it for my kids to ride and abuse and then I plan on stripping it for the goodies. Now people are telling me certain ones, like mine, are valuable. I have seen many colors, Mine is Chrome and Red, Does anybody know the story on these. Rick
