I wouldn't even consider wearing a helmet on a MB.But I live in a fairly small town and my commutes are fairly tame,also by law Azins are not required to wear one.I treat these very much like bicycles and I know I would never use a helmet on a bicycle.
I went out to L.A. last weekend,around the Long beach area and the traffic was so intense I don't know if I would be comfortable with a MB, I guess you have to use the sidewalk alot,didn't see many bike lanes where I was,definitely helmet area there........Peace
If you don't wear a helmet gravity will get you sooner or later
a head will crack nicely especially on cement which is harder and less for giving than pavment!!!
its a week after my crack up and I am still recovering thanks only to my helmet a good one weighs very little and does an amazing job.
I could hear my helmet cracking apart and my head was completely undamaged, I could even see parts of it flying away from me!
Use one it can save your life.
I have ridden many thousands of miles on a bike and i used to think helmets were useless NOT ANY MORE, that was the first time i was thrown from my bike and I have had minor accidents before while riding a bike.
I don't want to see anyone seriously hurt so please reconsider.
