Thanks people for all your comments. Some good news from seller. The rear dropout spacing turns out to be 130mm and it has 32-622 (700c) tyres on it. This is another reason to choose a city bike rather than a road bike to my wife. She'll never be happy on 23mm or 25mm tyres. And the more I think more about the issue the more confident I am about this choice. If she grows to be a competitive rider in years I can get an Italian road frame later.
