I had one of those - was, by FAR, the heaviest BMX on track on any given day. But even I couldn't break it - had many moer groot sloege on it. One stands out in particular - a local kid (riding a SuperGoose of course) convinced his cousin to park his Cortina on the back of one of the jumps at Zita park BMX track - all the big-shots tried clearing it and mostly failed. I came in from the blindside (being a few years younger than most other riders there) and pedalled like a madman. Cleared the bakkie, plus another 10 or so feet, landed on the flat and bought the whole of Garfontein Agricultural Holdings. Banged my knee up all bloody, but got up, bent my handlebar straight, got on the bike and pedalled home. Ahhh, what a day.
