Basically a Backside Bigspin is a combination of a Backside 180 and a Pop Shove-It. So the board turns 360 degrees while your body turns only 180 degrees. The Backside Big Spin is a little different from the normal Backside Pop Shove-It because with Backside Bigspins you need to scoop your tail more. Take your time and be patient because for this trick you need some time to get the right technique. Learn here how to do a BS Bigspin!
