Please, if you have any real studies of how much a helmet does not help, please share them. As of yet I can not find any creditable source in which bicycle helmets are shown NOT to reduce risk of head injury when worn.
So, please share your sources(not hearsay and anecdotal stories) showing that bicycle helmets do not reduce the risk of becoming permanently brain damaged.
I would love to see a picture of your recumbent also, as this thread deals directly with recumbent bikes.
