If the o.p. wants a range extender, the most practical idea is to use the trailer to carry extra battery capacity. Most generators are not built with mobility in mind so they are unnecessarily heavy. A motor designed for 110V AC is also not going to be a willing participant in the project. It will not have the proper hardpoints to be mounted on the bicycle, or on the trailer for that matter, and it will be twice as heavy as it needs to be. Overweight generator+ overweight motor+ kludgy drive system = failure.
