Needing a drivers license for a motorized bicycle in Wisconsin is news to me. Despite that, I am surprised using a gas motorized bike is not more popular in Wisconsin than it is. Where I am familiar in the southeastern part of the state, the speed limit in urban areas seems lower than in northeastern Illinois. In Kenosha county, a small town speed limit of 25 mph is not uncommon. In the larger city of Kenosha, the speed limit is 30 for the most part. In northeastern Illinois the urban speed limit is more like 35 mph.
With a 25 or 3o mph urban limit, the better option is take the lane as opposed to riding near the shoulder. Take the lane on Main St. and go full throttle! A Harley rider would not think of trying it.
