Wide bars, short stem, baggy clothes, BMX helmet, platform pedals, sneakers, Spooky bike, absolutely WFO into that berm. What is that in the background on the left? It looks a bit like the ass end of a pickup truck under a tarp. And the orange stick on the ground just behind the bike, is this some kind of slalom course? Or a wayward wiffle ball bat, perhaps? Those games do tend to get a bit out of hand.
