Thanks. I was looking at the Orbrea Gain D40, which looks like a great bike but have has a number of issues for what I want to do - limited power / range, integrated battery making charging off the bike impossible and having now seen one, probably won't easily take mudguards or a rack.
As a result I've gone back to trying to convert the Audax bike I already have.
