First memory of riding a bike?
I was fortunate to grow up on a short, quiet but hilly road in Hornsby with dead ends at both ends. The road also had a creek running under it, and was surrounded by suburban bush. Much of my childhood was spent with friends building tracks and jumps for BMX bikes, skateboards, scooters, billycarts and anything else that rolled.
