Cool review! it seems the bike fits your boy perfectly, we love woom bikes, the geometry is just right for the kiddos, also I hate to be that person but try to get your boy a helmet no matter if he is riding in the neighborhood, my 6 year old girl had a crash recently going much slower than your boy, and we got lucky nothing happened to her, but she smashed the helmet pretty hard, I had a good helmet on her, (Bontrager Starvos in XS).
