Only had personal experience with one Huffy that I inherited from my sister. A 26" wheeled 10 speed horror. It was unmaintainable. If a component moved, it bound up, if it was a screw it unscrewed. Bartape would unravel on it's own and tangle in the spokes, usually when I managed to get it up to speed. The brakes dragged and didn't clamp the rim. Have no idea what happened to it after I threw it (literally) into the back of the garage. If it was the only bike I'd ridden I would have never ridden another bike.

If I could get my hands on it today, the derailluers would be trashed. Make it a single speed. Bolt up a decent set of brakes, swap out the weirdly shaped drop bars and stamped stem and it might be a good beater. It sold for about $30 in the late 70s; that was too cheap to make a functional multispeed bike.

Ridng a Huffy meant you were a social pariah. Deserved a beating.
