What is a pre-hop

Hey there everybody.

Yesterday I learned to SIF hop and can actually SIF higher than SI but I keep hearing that you go higher by pre-hopping.

Does anyone have a video or a good explanation of what a pre-hop is?

its a small hop you take before the big one, to aid compression of the tyre, observe JH using a huge one to get the world record.

klinton pretty much said it but it isn’t always giant like that one in the vid. Watch any amature uni vid and most riders just do some small hops before unispins and hops to gain some balance and the right time to do the trick.
