Metallic orange Stingray. I was six. I remember my dad paid $18 for it, and it came partially disassembled in a box. It wasn't exactly bmx, but I rode it as if it was.

My coolest bike was a metallic brown Vista 5 speed, with the cantilevered frame, banana seat, and monkey-hanger bars. It's prominent feature was a big honking stick shift on the top tube with punched-out holes on the lever to make it look super sporty. It had whitewall tires, and a huge slick on the back. Hey, it was the 70's!
