It was inevitable, I suppose, the return of the monochrome BMX bike. Haven't seen any in NYC yet (besides the ubiquitous all-black versions, which have never gone out of style and represent more of a complete lack of obsession with color than an unhealthy one), but a quick spin around the web reveals a couple of freshly built examples:
The first one I saw was this all-white Kink. Quite the photo, huh? It reminded me of two things—ghost bikes, which are locked to signposts and light poles to memorialize cyclists who were killed (or injured) near the spot, and the all-white GT Pro Freestyle Tour that came out in the '80s during a Euro craze (if I'm not mistaken, BMX Plus! did an all-white "Project Euro" as well):
The only mystery about the Kink are the tires, which I expect are Primo Walls. Not the best choice for a current bike, but white tires are hard to come by these days. (If you're going to ride this bike, stock up.) I'm pretty sure the last time I had a set I also had white Z-Rims. Also, don't lock it up in a major city unless you want people to assume it's a tribute to the dead and get REALLY mad at you when you unlock it.
Then there was this all-red Fit Hawk, which was posted on the Fit site around the same time as they announced the availability of the red frame and parts. Like the white Kink, it was built by a shop (and I'd be curious to know whether either of them actually sell).
The Fit, like the Kink, appears to be all current with the exception of the tires, in this case Primo V-Monsters. They made V-Monsters in blue as well, so one would hope someone would make a Crip Hawk to go with the Blood version. (I'm surprised by how well the tones match, despite the use of both flat and gloss red, and paint and anodization and rubber.)
My favorite mostly monochrome bike was a Pro Performer that Eddie Fiola rode back in the mid-'80s, a recent semi-accurate reproduction which is shown here:
Given the black tires and the gold and chrome parts, it's more like one of Aaron Ross's neon monstrosities than the unicolors above. But it wouldn't surprise me one bit if colored tires made a comeback sometime soon. What goes around, comes around.
