Hundreds, if not thousands, of bikers gathered at the city's iconic Brandenburg Gate, taking several routes to reach it and demonstrably lining the square with their bikes.

One protester wore a jacket saying, "If we're too loud, you're too old".

The initiative seeks to limit the noise made by motorcycles to no louder than the sound of a truck or lawnmower, and also includes a proposal for motorcycle driving bans on Sundays and holidays.
