I got a bright yellow (orangish?) Nishiki bmx bike in a trade. It's about 15-20lbs. He told me it's a 2010 diamondback nishiki bmx bike. I know that nishiki is it's own brand, but he claims it said something in the original manual that said diamondback or something. He told me he paid like $300 for it in California during a vacation. I don't really know what this bike is or if it's good. Does anyone know anything about this bike? Thank you.
