Learning to ride a bike

When Lilo was about 5, she taught herself how to ride a bike. We followed the "european model" which we learned from our friends. There, they take the pedals and the training wheels off, and lower the seat so the kid can straddle the bike and "scoot along". (Hence, there is a wooden bike at REI that has no pedals or training wheels called the "SKOOT" which teaches a kid to bike".
Anyway, after a few weeks of skooting around, Lilo was able to balance herself and start biking. I felt like a bad dad because I never helped her to learn to bike..
Fast forward to today:
For months, we have been telling Stitch he should take the training wheels and pedals off to learn to ride. "But what if I hurt myself? what if I fall and hurt myself?" was his response. He would throw a bit of a trantrum. So, we left him alone.
Last week, he came up to me and asked to take the pedals and training wheels off. I said, "are you sure? Are you sure you want to do that? won't you get hurt?"
He responded, "My friends W and C are riding bikes now, I want to ride too." So I took them off.
Less than 24 hours later he came over to me and said, "put the pedals back on, I can ride now".
I didn't believe him. I said, "are you sure? I don't think so" and went back to work.
A few minute later, he pestered me again. So I asked him to show me.
I came outside, gave him a quick push...and he was off!! Not only was he able to coast with his feet up, but he actually put his feet on the arms of the crank where the pedals would be...and started pedalling. I was shocked. He learned to bike in one day!
I've come to realize that the two of them have different learning styles and motivations. Lilo will focus on something until she masters it. J just watches and does nothing. Finally, one day, he'll get the motivation, and that's the end of it! He will be the challenging one to continue to learn how to motivate!
