I've done the searches, without a clear result. I would like an answer and not a lecture about searches.

If my paperwork shows 49cc engine, gasoline powered, which of the following do I need to stay out of trouble?

1. Do I need a plate / blue plate? Will primarily be riding the bike lane in Shanghai.

2. I have a China driver's license; do I need a China motorcycle license for 49cc?

3. Do I need insurance on a 49cc scooter?

Thank you for your reply
