Hello, I've just decided to ride from John oGroats to Lands End next summer to raise money for a charity and I've been looking for a bike. It's been 30 years since I last rode a bike and I know absolutely nothing about them. I also have very little money to spend on this adventure so I'm looking for something seconhand. I found this http://cgi.ebay.co.uk/Touring-cycle...ryZ33503QQssPageNameZWDVWQQrdZ1QQcmdZViewItem on ebay and would like to ask your advise as to whether or not this is a good buy and also what questions I should ask the seller. Kathy.
