Re: Used bikes, crazy $$$$
You can not beat scrap yards.
Befriend the metal scrappers in your vicinity in whatever language you need to speak.
I ask them to pull over all the time in Los Angeles bikes 5-15 bucks depending.
Past monday I was cutting through a gas station and an older Mexican scrapper couple (man and wife)were arranging their hauling truck-- along side was a TORKER BERMUDA CRUISER WITHOUT A REAR WHEEL 10 bucks later- smiles on their faces and mine!!! it was on my car bike rack-- happy to come home with me.
Enjoy the hunt-- ride safe
