Clunkers. The early MTB pioneers were racing them downhill in SoCal during the mid 70s. The bikes had coaster brakes which failed often with that kind if usage. Then they invented the MTB and everything changed.

Electra still makes them but they're quite heavy and too expensive. One could buy a much more useful urban IGH or 1x derailleur bike for the same amount. Like a Kona Dew.

Indeed, I own a 60's clunker, and enjoy having it for the experience and audacity of riding it, but you take the basic clunker concept and replace every piece with its modern counterpart, and now you've got a much better bike. For instance I wouldn't build up a new bike with steel rims, or expect any kind of performance out of a coaster brake.
