This is a video of pro freeride mountain biker Sam Pilgrim building a mountain bike skateboard hybrid and attempting to do tricks around a skatepark on the thing. You may previously recall Sam riding a pennyfarthing bicycle downhill and around a BMX track. Or, if you’re like me, you don’t recall that and had to be reminded by your girlfriend that you’ve posted this guy before. My poor, poor brain. Can you huff ginkgo biloba?
