I was talking with a fellow motorbiker yesterday about the legality of motor assisted bicycles on the highways in Pennsylvania. We were talking about the many people would like to ride a motor assisted bicycle for various reasons, but are unsure of the legal status in Pennsylvania. He gave me a copy of the Pennsylvania Fact Sheet from the Bureau of Motor Vehicles, of which he always carries a copy with his motored bike. He is using a Happy Time motor on a Schwinn cruiser bicycle. On nice weather days he rides his bike everywhere, including riding to work at the local college. He has never been stopped on his bike, and the Police just "smile and wave: when he drives bye. Maybe this will be the answer for the people in Pennsylvania. I have posted a copy for everyone to share. Thanks / Buck
