@juliette@mastodon.green Two data points from the US, suburban east coast. In my neighborhood I don't see many teens on bikes at all; mostly elementary and pre-teen kids. That seems to skew towards boys but I just saw three girls riding together the other day. On the campus of my university just outside of Washington DC, LOTS of bikes, and probably a 50/50 split. That's not counting all the micro-mobility scooters, which I think leads towards the femme side.
