Although I doubt too many folks will take issue, I am thinking that many places you would have difficulty operating a motorized push trailer mounted on a bicycle legally upon public roadways.
The laws may vary by state. The laws are actually still a bit confusing and this has caused a bit of debate here, even amongst professionals who ought to know. As an example, below I've pasted in some of the relevant definitions under Illinois Law at the bottom. They are long and the points may be difficult to decipher. The key points being:
- if the combination of the trailer and the bicycle is self propelled, then it is a motor vehicle.
-It may not be a moped or a motor driven cycle if it has more than three wheels in total touching the ground. It may be a division one passenger vehicle. (As such, I don't see any way that one would be able to legally operate such a vehicle with a two wheel motorized trailer pushing a bicycle legally on any public road in Illinois under the existing laws) (The ambiguous thing being that you can separate the trailer from the bike if I understand what you are building)
- drivers license required for any moped or motor driven cycle, license class dependent upon which type of vehicle, see the definitions below for definitions. License required for driving passenger cars as well.
- title required for any moped or motor driven cycle, as well as for passenger vehicles.
- insurance required for any motor driven cycle or moped or passenger vehicle.
- registration required for any motor driven cycle or moped upon any public road.

This is general information for Illinois, and is not intended as legal advise, also the information is not guaranteed for accuracy.
These laws are specific to where I am, in the state of Illinois in the U.S.A. Your local laws may vary of course.
