I had a bad crash on christmas eve. I was standing up riding, and right when I was about to push my right leg down the chain came off. My foot went down so hard I lost my balance, I twisted the handlebars by accident, anyways I was going down, and I hit the grooved [weird] pavement. and I almost fainted after seeing the blood poring from my left elbow and some from my right knuckle and my right arm. After I made it walking home I bandaged up, and after looking over my bike the bike must of flipped over, by the scrapes on the brake levers. No broken bones and by christmas I was riding again this was my first really bad crash.
