I think the reality of most people using bikes in rather low stakes situations also changes things heavily. That is, many are riding bikes that I would not trust down a hill going 30+mph. But, notably, most people are not going anywhere close to 30mph on a bicycle. To that end, you are correct that most people are just needing to clean their bike. Replace the occasional consumable part of it, maybe. Keep it clean, though, and you are unlikely to need to replace any parts anytime soon. Edit: And, again, limit this to ebikes and things change pretty rapidly. It is trivial to get an ebike to 25mph.
