Perhaps it's region dependent, but mopeds in the US typically don't have pedals.

This source is from the UK but applies similarly

Hmm for some reason I always thought it was a shortening of "motorised pedestrian" haha.

On the other hand, I have seen models with holes next to the transmission that can accept a pair of removable pedals stowed under the seat. Completely worthless for locomotion, but sufficient to be classified as a bicycle for legal reasons.

This isn’t true in practice for any country that uses English as a first language, where moped simply means an underpowered scooter.
