Do like I did, call your local Sheriff, City or Township Police and check with them, I also have a friend who works at the Secretary of State Office in licensing and she said no, her father-in-law also built a bike and has no problems. I think the only thing that might be required if at all might be eye protection and a pair of sunglasses would take care of that. In the town (Mattawan, MI) I live in the cops would ticket you for even looking crosseyed at a rock and I've had no problems.But, when you're out having fun on a nice summer day with friends you don't want to be hauled in and your bike taken and then have to try to fix the problem..
