I finally got in touch with Idaho Parks and Rec. today. I ask about Electric bikes and Snowdogs needing tags. The Snowdogs need tags and the bikes no. The bikes are regulated by class and speed. Parks and Rec's phone no. is 208-334-4199. II get my boat and snowmobile tags by mail every year so I don't know about in person. Good luck on the fishing this year,and be safe.
