Display window (1): Bike and waterski

It's time to start a new mini series !
When walking the last stretch from my train/tram stop to work, I realized that the area has some interesting, sometimes a bit weird aspects. So, let's go with some display windows. Starting today with something directed to a mobile, young and sporty audience: Bike and waterski. Both helpful alternatives compared to being stuck in a traffic jam.

Honestly - I have no idea what it is about. I couldn't see any shop or specific sign around. Except this empty bottle of champagne, setting some counterpoint.
