How old were you when you learned how to swim and ride a bike?

DS was 3 with training wheels and 4 without. He won't even put his head under the water but I am hoping he will learn to swim with school lessons next summer.

i started swimming lessons very early, i could actually swim independently for short distances from 18 months. i was able to ride a bike at around 4 or 5 too i think?
