I originally saw this on Seth’s Bike Hacks youtube channel and duplicated it as closely as I could. I wanted to formalize what I did in case it sucked, or was awesome, I could easily iterate. I deliberately made this more on the mellow side as kickers go, as I’m not so great on the bike if that bike is flying thru the air.
I used 1/2” plywood for decking, but even with what appears to be a ‘gentle’ curve, I could not get the ply to conform to the curve without partially sawing thru the underside w/ circular saw….made lots of partial cuts thru underside, then screwed down at the two lower corners, then jumped on the ply to ‘crack’ it into the curve shape. Even after that, it had enough residual tension (trying to straighten itself back out) that a few screw heads broke off when trying to fully screw it down to the 2x4 cross-supports. Wear safety glasses.
And wear a helmet, don’t hurt yourself.
