6.5kg is very light (at least it is to me), perhaps try those thing that you hook vegetable on to weight it in the supermarket? do they have those for heavy object like bike?
i think the way forward is to physically go into the supermarket with the bike. bet those veggie scales are well accurate. sainsbury's whitechapel - no one would bat an eyelid...
