I taught my older son to bike like all parents by breaking my back running along them. All stressed out he will die if he falls. It took a week or so. His younger brother learned in 15 minutes when we were on vacation because otherwise he woukd not have been able to play with him and some friends. The key thing is that the older brother won't have much pity, either you follow or you don't. I saw that in plenty other cases where the younger one had to learn fast, and he learned much quicker and earlier too. Us being imperfect parents, he also watched some movies earlier than his brother did. I find on my one data point analysis that the way children are raised are very different between siblings.
