I was exactly the same as a little’un.
My dad was teaching me to ride my bike (I think I was about 4 or 5) took the stabilizers off I stood back and looked a bit worried (apparently) and my littel sister – who’s 19 months younger than me – ditched her trike and buggered off down the road on my bike never having ridden one like it before!!
I do think that girls tend to be better balanced than boys at that age, but it all goes out of the window once teenage years kick in.
He’ll get the hang of it, don’t worry. As for the non-sporting future, i did pretty well, HIgh School colours for Rugby, Football, Cricket & athletics, county school of excellence @ footy, & always well placed in county XC as a kid
