I was thinking about that when I was dropping my 6 year old off at some hobbies earlier - it’s pretty much expected to have learned how to ride a bicycle before starting school, and it massively expands the area you can go to by yourself. When she went to school by bicycle she can easily make a detour via a shop to spend some pocket money before coming home, while by foot that’d be rather time consuming.
Quite a lot of friends from outside of Europe either can’t ride a bicycle, or were learning it as adult after moving here, though.
edit: the high number of replies mentioning “swimming” made me realize that I had that filed as a basic skill pretty much everybody has - probably due to swimming lessons being a mandatory part of school education here.
We learned swimming in primary school in Germany, no opting out.
But having lived in several African countries and now in China, it’s surprising how many people not only can’t swim, but are deathly afraid of water.
Maybe that’s different from state to state. I grew up in Hessen but don’t remember having mandatory swimming lessons. I learned it mostly on my own so I don’t even have a „Seepferdchen“ and know a few people from NRW who don’t either. I remember there was the option to do it in school but not sure why I didn’t take it then.
Either way, not being able to swim at all is pretty rare in Germany because going to the pool is a popular activity for kids here.
Same in the US. Most schools do not have their own pool and swimming is not a required skill. Tons of people don’t know how to swim here.
Many schools in Germany also do not have their own pools. You will be transported on a bus to the closest one.
There is schools with their own pool? Heck, half the inner city schools dont have a proper gym hall and use public ones.
