The deadly treadly I remember was the first BMX bike in australia in around 1973 I really remember it because it had plastic fuel tank and mudguards and motor and My parents had it on the far side of their bed and I saw it and couldn't see the pedals and thought it was a motorbike after a seconds disapointment I was thrilled it was the best Deadly Treadly in my neighbourhood and I was envied amoung all my mates
