We are hiring a campervan in and our of Munich for a month, early mid September to mid October and would like to take bicycles with us. we don't want to do long distances on the bike, just to cycle around towns instead of using the campervan and to travel from camping grounds to rail etc. The rental people have advised us to buy bikes and then donate them to local charity shops. Does anyone have any ideas of where we could get cheap bikes (in Australia it would be somewhere like KMart) or of how to find second hand bikes. Any thrift stores or websites where you can get second hand goods. Hope someone can help with some suggestions.
