5.5 feet tall with a 9.5 foot diameter. That gets you a 68 degree lip, which is pretty steep. I'd consider doing maybe a 10 foot diameter to get a little less up.
Trail: Get it up, Night and day. Riders: Select. Description: Ny backyard jump set so far, 5.5 foot steel kicker to a choice of a little booter or a wooden drop into another dirt kicker. More to come.
