I am looking for something like a cheap and cheerful "city bike" that I can ride to a bar/town wherever, chain it up and come back a couple of hours later and to find it in the state that I left it with all essential components present and correct (i.e saddle, wheels etc). Basically, I want something no-one else wants to nick!
All of the people I have asked have told me that eBay is the solution, but I am not a man of the world and I don't trust the interweb. I would rather get one from a dealer/bike shop so they can tell me if the bike fits me and that I know when I am hooning it down a hill there is a good chance of the brakes working.
I have consulted one of my best friends, Google.de, but he couldn't shed much light except suggesting phoning every bike shop in Frankfurt.
I have called a couple of my local shops, and they all said that they don't have anything in at the moment, but every once in a while have a second hand bike and should call them back every week or so.
Does anyone know a shop where there is generally a good stock of reasonable second hand bikes?
