No idea.. I have no kids :) Not sure at what age they are capable of what. Of course I was also young but like I said in the Netherlands bikes are king of the road. And I lived in a quiet suburb. It also depends on the area. If they'd just cycle to school in a quiet area it'd be ok more easily than if they have to cross roads like Passeig de Gracia, Arago or Gran Via, or some of the busier Rondas of course. I rarely cycle here anyway. I mainly walk, I don't feel safe enough cycling. There's some cycle lanes but not in every street, and often not well connected, or they suddenly jump to another side (the ones on Diagonal tend to do this), mix with pedestrians etc.
