I had a dream last night and remembered it when I woke up. I was riding a bike down the side of a building, not straight down but the bike was tilted out from the building and to keep my balance and keep the tires on the wall I was leaning slightly toward the wall. and going down the side of the building at an angle from like top right down to bottom left of the side of the building. At the bottom I was able to transition smoothly and ride on down the sidewalk. I figure Vassago has done some crazy stuff and would know if this is possible. Can you ride a BMX bike down a vertical surface such as a wall without falling away from the wall if you lean the bike away from the surface and lean your body to the surface. to try to keep the tires on the vertical surface. And if so can you do it down like a 5 story brick building or just a short vertical part of a pool wall or vert ramp? Sort of like in the picture.
