i've never tried it on bikes, but i know whenever i'm looking for a musical instrument, the time frame before and during christmas is great. people are always trying to sell guitars/amps/etc before christmas to get money to buy other things. but then there are also a lot of people looking for them for gifts. ebay is awesome if you have time to check it christmas day. it seems like no one else ever checks it on christmas. i've gotten some awesome stuff that way.
