Can you learn BMX stunts from a pro in one afternoon?

Surely they can't be as hard as they look? Erm, about that...

Most of us have seen bike tricks completed completed by pro BMX riders or stunt performers and thought to ourselves, 'Wow, that looks really quite hard'. But are they as hard as they actually look? Well, as it turns out, yes they most definitely are. We caught up with a BMX rider on top of a very tall building in London to see if he could, in a rather short space of time, try and teach us some tricks. Did he succeed? That's not for us to say right now. But all we'll say is that there were lots of extremely sore shins.
