What must be constantly operative on a motorized bicycle?

For motorized bicycles, it is required that all lighting and safety devices are always operational. This includes permanent dipped headlights (to ensure you are visible at all times), a rear light (so you are visible from behind), and a rear reflector (which enhances visibility in low light conditions). Having all these features functioning properly increases your safety and meets the legal requirements on German roads. Always check your bike before every ride to ensure everything is working.
