I'm planning on buying a helmet and a GoPro soon so I can record my bicycle rides around my neighborhood and when I visit my brother in his subdivision. I did some research and I found that an GoPro with a normal bicycle helmet because I want to use a GoPro Motorcycle helmet mic since Built-in GoPro Mics Doesn't do good with wind protection (Referring to the GoPro Hero 4). and I don't know if it is legal or not to use a motorcycle helmet on a bicycle. someone please help!
