Craigslist for very cheap. Instant cash infusion but be prepared to loose your shirt if you really really need the money. Ebay takes fees and paypal takes days to transfer the cash to your account....then if the buyer is shady they can dispute the purchase and eBay takes the money back and "holds" it until you basically make the buyer happy. Pawn shops here won't give you hardly anything for a bike, I just don't think they sell well for them so they aren't even interested.
