Mopeds are all motorized two- or three-wheelers with a maximum displacement of 50 cc or up to 4 kW engine power and a design-related maximum speed of not more than 45 km / h (for exceptions 60 km / h). This definition refers Mofas, but also u.a. Scooters and mopeds. The traffic sign shown here, however, refers exclusively to mopeds.
