YAAY, I just hopped up my two set on my back porch, each step is only 4", which i can easily hop, but i’ve been so intimiated by it that i couldnt do it, and tonite i conquered my fears and can do it successfully 70% of the time!! I also can hop “down” my 4 set most of the time, but i’m too scared to ride down it, i’ve done it before, and the two last times i did it i did it successfully, but still im scared
