When that older DX game port was released, I think it took like 3 or 4 days for them to take it down. Probably even like a ~~patch~~ stomp tuesday situation when the interns hand off the script detections off to the lawyers.
It might take a bit longer if people stopped using sites like Youtube and Github, and tried not to include trademarked terms (or super-identifiable audiovisual content) anywhere.
I'm pretty sure that's just about using the pedals, as in having an ebike with a throttle won't be an issue (even though throttles are extremely common, mine is 250w + EU speed limit and has a half-twist throttle).
Not that the legislation is 100% unrelated, but I see it likely more of just accepting that people have been going faster for a while.
