Hi, I want to build some obstacles in my garden. I am going to build something where i start from ground then pedal kick onto this pole (well not a poll a bit of wood on legs - see this image) and you pedal kick onto it - say knee height then you have another one that is taller then a table to get on, just to practice gapping and stuff, and balance on the back wheel. What other stuff could I build? Thanks, Danny.
