To make a bike "attractive" just do simple things that a lot of people overlook.
Use matching tire sets, matching wheel sets, color-coordinate your ano'd parts, and use a "scheme".
I CANT STAND bikes with mismatched rims, a panaracer fire or michelin Hot S tire, and a black or maxxis orange tire on the other end. Then they have a chrome rim on one end, with a stealth rim on the other end.
A silver stem with black bars, and black cranks with orange pedals and a turd brown frame.... or something goofy like that.
Just match up yo sh1t and all will be well.
Mine's got ALL black parts, with a silver frame. The result? It looks *CLEAN*
Nuff said.
