Mist, ich hab meine Reifen mangels Profil erst vor 2 Wochen getauscht. Aber beim nächsten Mal bzw beim Zweitrad werde ich die mal aufziehen lassen. :)

In Germany, official government buildings will have the flag on or in front of it, usually next to a bunch of other (eu, county, city...).

Private citizens will fly the flag for sports reasons, or in more right-wing communities they'll fly either the official flag or the old black-white-red one from empire times. Most people will look at you funny for flying the flag when no sports or eurovision are/is going on.
There is really very little "neutral" ground here.

I have a Riese&Müller Vario Swing. I wanted something to transport bigger loads, but also still a bike. So I got a Citybike with a trailer.
The thing is a year old now, and I've used it much more than just for shopping. In the height of summer, I also use it for commuting (without trailer), because I wouldn't make it home otherwise in the afternoon heat. And whenever I go somewhere I have to be presentable, it's still better than public transport.
It doesn't need much maintenance apart from what every bike needs, the belt is even easier than a chain, and the battery gets me quite far.

I also have "normal" trekking bike. And I think if I buy another ebike, it would not be a citybike again. The low access is nice, but the seating position is not for longer trips.
