I don't suggest this method but I thought everyone might be amused by my story of learning to ride.
My father figured the best way to have me learn quickly was to put me on the bike at the top of a steep grassy hill that gradually flattened at the bottom. The first time he pushed me down the hill I crashed of course. After the requisite crying. He pushed me down a second time. The second time I did not crash.
Fear can be a powerful motivator. I always remind my father of this story when biking comes up. Also, this took place back in the days before helmets were considered mandatory equipment.
