Chris I do think some people are being harsh on both you and your partner, assuming that neither of you have any bike control when they probably haven't met you, what with you living outside zone one of the tube (I bet 'wigan' will, if that is his name, hasn't even made it as far as finchley)... And for the sake of clarity I will point out that direct drive (which isn't the same as a fixed bike using a chain as transmisson and brake) without any other brake is infact road legal as direct drive counts as two brakes.
You previously asked for someone to give an example of why a single brake would be dangerous. Can I ask a question, if your girlfriend was cycling along at a fairly fast pace pulled on the brake and a fray within the cablehousing (which therefore you wouldn't see in your meticulas checks) caused the brake cable to snap, what would she do?
The reason a fixed drive train is safer (although I'd still have a second brake on a 'safety' bike) is because you can see wear on a chain and so being a careful mechanic should be enough to stop you ever having to think about the above question (unless of course you dehouse the brake everyday?!). Having said that, every brakeless rider I've met has known the answer to the above question... Hopefully your girlfriend will too?
