I mean dedicated "cycle paths" that are not a "benutzungspflichtiger Radweg" (sign 237), but are legal to cycle on. They usually are on the same level as the sidewalk and only visually distinct in some form. They were typically constructed in the sixties or seventies, are too narrow to overtake or use with a cargo bike, and suffer from the same visibility problems that illegally cycling on the sidewalk has.
