Mopeds have pedals but mostly function by a throttle. I never knew a single person that used the pedals unless they were out of gas. My bike (class 2, mid-engine) does not work without pedals and makes commuting feasible in areas with a lot of hills. I always pedal past the 28mph max and it’s 0 engine assist in those moments. You going to regulate that then you need to regulate all the spandex guys on the weekends too.
