Yeah, he did well. Because he's on a smaller bike (smaller wheel circumference) he gets jumped at the start off the ramp as he has to work harder to go the same distance as the others. His dad has has changed the sprocket which mitigates that somewhat but it makes the bike harder to push. The solution is build leg strength which is happening and the good thing is that it forces him to work harder which he does.

He focuses on fun first though, and he loves it, and that's what's important.

Thanks for your comment.
