Don't kid yourself that your bike has miraculously melted into the background just by being black....
It has gained a number of admiring comments on this forum, so THEY must have noticed it, and anyone seeing it in the flesh will see that it is a quality, new bike which just happens to be all black.
In my experience, when people try to cover something up they normally just succeed in making it more apparent.
So at the risk of teaching you to suck eggs, don't get complacent about your "invisible" bike because the thieving bustards are out there.
