The first pic I ever saw of some over tweaking something was Todd Anderson, who at that point in time-1985-was riding for Redline. I picked up a magazine in a mock 711 next to Faze 7 BMX centre in Waltham Cross, Todd was cranking a twisted lookback with his feet on the cranks arms, and his front wheel hitting his shin, I'd never seen this before, until that point a pic of a look back was anything with bars passed 90 degrees and the back end high.
After doing a BMX 'zine for ten years (1987 - 1996) FATBMX made it on the internet. The year was 1998. Here to stay.
