Working on our lifestyle products here at Trek, one of the biggest requests we get is "can you just make the bike black? I don't want to stand out." The thing about that statement is that it's not totally true and no, we can't make an entire line of black bikes. Yes, some people may not want to "stand out" but everybody wants to be at least somewhat noticed. If that statement were true, there'd be no reason to make the Trek District. And then there would be no trekdistrict.com. The underlying truth is that the requestor is probably scared that somebody will rip their bike off and they'd rather not see their investment in the hands of bicycle miscrients.
Well, now there's a way to deflect the attention from your sweet ride without haveing to actually sacrifice the paint.
UK-based desinger Dominic Wilcox has come up with a solution that is simple but seemingly effective. Dominic has come up with some super-realistic scratch and rust decals that can be slapped over a nice paint job to give the appearance of "shabbyness". You can deflect thieves while keeping a clean aesthetic for only £3.99 (which is only, like, 74 US dollars). While Dominic makes no guarentee as to the effectiveness of his decals, he has seen some success with his own bike in London. Capital idea! Check him out here.
BTW: While these are a great idea, I'm not guarenteeing they will work. You want to keep your bike? Buy a big lock.
