my son, who just turned 9 about a month ago, only just learned to ride his bike.

part of the problem was that there’s a few things that he’s really good at, and if other things take a bit more work or practice, he tends to give up quickly. so we really didn’t push him too hard on the bike thing. and getting the balance right was a big thing for him too, he always tended to lean too much when riding, so i think it helped encouraging him to sit up straight.

but this year he was determined, and it just sort of happened. he still struggles a bit getting started but once he’s going he’s good.

not sure if that helps? just our recent experience.
