@realSiegfried I am aware the motorcyclists in the US also call themselves bikers, but I have never been mistook for someone who rides a motorcycle nor have I misunderstood what someone else was saying.
The culture around the two things are extremely different (I’d say motorcyclists are usually assholes), and the context of the conversation or the context of who the person is make it clear.
However, when speaking French (I’m in France now) I use « cycliste » for myself.
