i took the video from the deck in my back yard. some new neighbors have moved in adjacent to my yard, and they wasted no time building a couple of pretty trick ramps. we thought that they were building skate board ramps, but to our pleasant surprise, they were building them for bikes.
that white 2 x 4 is pretty high off the tops of the ramps...and they don't have much room to get speed. it's almost like slow motion!
the kids really liked watching.
