I'm a new rider, and looking to get my first bike used. I've been checking out cycletrader.com and craigslist.com for used bikes, but am unsure about how to proceed. Many of the sellers request that you come with cash in hand...something I'm leery about doing after hearing a lot of crazy stories about people being robbed or worse. I also heard from my Motorcycle safe rider course instructor that you should NEVER go to meet a seller with cash in hand. Also, how do I set up having the seller bring the bike to a mechanic (of my choice) to check it out? I'm a bit lost here. Any and all tips for used bike purchasing from online is greatly appreciated! Thanks folks!
