That can happen to anyone, don't blame yourself.
I had a similar attempt at this type of information extraction - to which I replied with something among the lines of "I keep my bikes under lock and key, right next to my 3 Alsatians' dog beds, they're police dogs, you see, cause my dad is a policeman, he used to be in a K9 unit but now he's armed response." It was an obvious lie (no idea if the would-be thief bought it), although hopefully at least it gave him a clear image that he wasn't going to be gathering any information from me...
The only reason I replied like that is that I could smell the security information gathering from a mile away - and the main reason for that is that it's a common thing to happen in eastern Europe, which is where I come from.
