I'm surprised nobody mentioned, but I when I was a kid I had a bike with training wheels, and when I learned to pedal fast enough, my grandpa just started to bend the holders of the "training wheels" a little bit upwards, so that they wouldn't be even with the two main wheels, and the bike would slant a little bit either right or left.

Riding a skewed bike was very annoying for me, and I learnt to keep the balance in a couple of days.
