~1980 I had a Mongoose with steel wheels, coaster brake, some sort of cast-iron/steel quill stem and if I saw a PK Ripper or an SE Quadangle I would turn green with envy. That PK seemed hyper-exotic since it was made of aluminum and the Quad was from another planet. I don’t want either now since a 50+ y/o guy riding a BMX bike looks absurd but back then, a Quad and holding hands with flaxen-locked Stacie H was the stuff of dreams.

FWIW - last I heard, an SE Quad frameset was around $4k. No idea what it would take to hold hands with Stacie H…
