Typical non-hub dynamo lasts like 30 years parked outside, and nice ones cost like $10 on Amazon. You smack it and they start whining at you. They are only barely more complicated than a stew pan.

Hub dynamos seem a bit more fragile, with a wire extending into the lightbulb, but never heard reliability is a concern with it...

Why do you think hub dynamos are more fragile? And what do you mean about a lightbulb?

I mean, it does have like, a wire between the hub and the lamp body. I think parent comment mentioned something about fragile wires when I posted the reply, I should have quoted it.
