I've had them all. Polished Chrome, Silver, Black, Red, Green...etc.
Currently, my mtn bike is white w/black,yellow and a tiny bit of red.
Road bike is Yellow and Blue.
BMX bike is Black w/Red & White.
I think a Red bike always looks the fastest.
A yellow bike is a beautiful thing!
A polished (either Chrome or Ball barnished) ranks right up there!
But, of all the colors, I always love a black bike. I don't really know why, but always have! And really, a Black w/Red bike!
