Wait, what??? I thought you were all hardcore DH and you're just learning proper bunny hops? I'm confused! Then again I guess you wouldn't need the ability to hop onto a picnic table if you almost never ride street haha. Either way, props on finally getting them.
I am hardcore DH, proper bunny hops are rarely needed on course.. at least that i've found. any kind of hop will do in the rare instances you hop over something instead of absorbing an object with 8 inches of lush travel.
Anyhow, I could only do about 8 inches of non proper hop... jumped up to 16+ within a week of proper hops.
