A word to the wise. I've sold a 2nd hand traditional bike on Ebay. I did state 'collection in person' , but then amended it to say I would accept someone arranging their own courier, not anticipating an international buyer. The buyer was from Austria, arranged their own courier and I duly boxed the bike, handed over to the courier and thought 'job done'. BUT ! I've been copied into an email from the courier to the buyer informing him that the bike is being held by Customs as they want to know if it is an electric bike or a 'classic bike'. If it is an electric bike it needs a certificate of conformity , if it is a 'classic' bike it comes under 'banned goods' for export from the UK to EU. I've done my bit in good faith; I'm just hoping that this problem doesn't come back to bite me. What do you think ?
