I didn’t mean that all bikes sold were UCI compliant as directly as that. The market has focused on pursuing a fairly narrow definition of performance for a bike in part because of the narrow definitions of racing cycling. That’s had knock on effects for the type of components that have been focussed on and developed. The near ubiquity of diamond frames over recumbents which prioritise comfortably for example.
I think we have seen that effect lesson over the last decade or so (e.g. belt drives for example). Ebikes help as they have very different markets, need different properties and have by definition no need to overlap with UCI compliance at all.
Of course its quite hard to unpick the other factors that have led the market to be cater so strongly to leisure market over the utility market but the UCI I think is up there in setting a cultural standard for what a bike is at the cost to alternatives.
