In fairness, they’ll last much more than 50 miles if kept inside and properly lubricated.

However, they use notoriously non-standard parts. So, if you want to fix your $100 bike, you’re looking at paying for someone to custom machine the replacement part.

You can’t even just find an old huffy and scavenge parts off those, since the geomoetries / threads / etc change constantly, so you’d need to find one made in the same production run as the one you are repairing.

They are disposable kid bikes. They don’t even make frames big enough for 6’ tall men. (and it is not even close; not sure what the cutoff is. 5’9”, maybe?)

not a typo :( search for "bicycle shaped object". huffy is one of those brands sold in big box stores to folks with little intention of serious use. riding these is so unpleasant there's actually a negative feedback loop.

Not a typo. They weren't road bikes. They were looks-like-but-aren't mountain bikes targeting kids. Real big when I was a kid in the 90s. Sold dirt cheap at ToysRUs and the like.
