Okay call me lame but I bought Landwaves for me.
With no pump tracks close by and a spouse who use divorce me if I tried to build one in my backyard- they were the best solution I found. They are meant to give me some low consequence, driveway skills practice and they do the job better than I expected. I got 4 ramps and 2 boxes- I can make several configurations that allow me to practice row/anti-row (Lee likes bikes), punches, small table top jumps, slow speed wheelie drops, bunny hops, pumping etc…
They are bulky, but easy to set-up and I think provide more versatility for different configurations. I got them from Amazon and the kit I got was about $400- 1 kit included the 4 ramps and a box and I got an additional box. This was pre-supply issues so I imagine the price has increased somewhat.
I store them outside but usually take them apart so neighborhood kids don’t help themselves to a jump.
