Why does Joeybike crash once a year? I've only crashed 3 times in 30 years and all but one of those was my own stupidity, I think I've gotten better at riding since I haven't crashed in around 20 years. If I crash tomorrow I'm going to be really mad at you all!! The one crash that was not my fault I slammed the top of my head into the side of a car doing about 18 mph, I'm pretty sure if I wasn't wearing a helmet I would probably not be able to type and spell out the words in this post since the helmet liner was crushed flat and the outer skin of the helmet was split thus my skull would have had to had the same damage if the helmet wasn't on. In one of the my fault accidents I slammed the side of my head onto and edge of a curb, again crushing the liner and cracking the skin of the helmet. The third accident I didn't hit my head until after the accident which I did with my hand for being so stupid! Those impacts to the head did give me a mild headache that went away within a few minutes, doc said I didn't have a concussion in either, I went to be checked out to be safe. Of course even though I use to mountain bike ride I was not trying to be aggressive due to fear of crashing and hitting rocks that I'm not sure if a helmet would do much, plus hitting rocks tears up the body and I'm allergic to pain, deep cuts and broken bones, so I never crashed doing that, all my crashes have been on the street on the road bike.
