Heres my story, care enough to read it, thanks for the help!
I've always loved barspins and thought they were a really great looking trick to mess around with, so I started learning them. I tried out the indoor bike. same night I put my bike back together and had hop half bars dialed no problem! Then I sorta got stuck with them for a while... later on I manned up, put some knee pads and went for full barspins in my garage. I used to throw my bars like xup but I fixed it and started throwing with one hand only. That day I tried going for full and i missed a couple times and the last try I caught one hand, lost balance and fell back. I fell and my peg went in my lower back, tailbone to be exact. I couldn't walk for a day and 5 minutes after I passed out. 1 month after that accident and now I did the indoor bike again and I can no longer do half bars or full bars. I always choke and hesitate to throw. Please give me help on what I should do to overcome that fear again, as I'd love to learn this trick.
