I tried for a while to master wheelies but I didn't get very far before I dedicated more of my time to bunnyhopping. But, I've got that down "enough" (a foot, maybe a foot and a half tops but that's more then enough for what I need. As long as I can get the rear wheel up, two wheels is a bonus of learning that

) so I might go back to trying wheelies.
I'll report back if I make any progress
