I tried this for the first time over the weekend and crashed really bad.
As soon as I put both feet on the pegs and let go the bike rotated forward and I smashed the ground with both elbows and the side of my head, my feet never left the pegs.
I'm pretty banged up and may need a few weeks to recover from it, I have an appointment to have my right arm X-Rayed today to see if I fractured it.
