Electric bicycle classes and Class 3 path speed

Iowa defines three e-bike classes up to 750 watts and generally applies bicycle rights and travel rules. On a bicycle path, trail, or bike lane, Class 3 speed is limited to the posted limit or 20 mph if none is posted. Operators under 16 may not operate Class 3 except as passengers; Class 3 requires a speedometer. No statewide e-bike-specific helmet rule was verified.
