I observed much more crowded bike lanes (in Hamburg), especially during the morning commute between 8 and 9. There were bicycle traffic jams in places where none were last year.

Also, I observed lots and lots of blue-tired rented bicycles during the summer, though their numbers seems to have reduced a lot since the weather got wet and cold.

The blue-tyred bikes are long-term rental bikes from https://swapfiets.com . They're a good deal for someone who is only living somewhere for ~6 months or less.
