Not sure if I just need more coffee or what… but I don’t exactly understand what this is…
It’s a board for trampolines. You strap it to your feet and then you jump on the trampoline and do tricks with it attached as if you were on a skateboard/snowboard/wake board.
some more details are needed to this post
though i get to know what the post wants to exhibit, there is a lack of clarity in the post
