Anybody else ever try this? It's arguably a somewhat basic trick, but it's definitely among the unforgiving tricks. I haven't tried this recently, but I used to try all sorts of bike stunts a few years back. I have never fallen while standing on the seat, but I have seen it happen. It's not a good situation to be in even as a spectator. I didn't have a BMX when I did this though. I was just using a small standard street bike.
