Even though you are hogging so much space compared with one little kid's bike? That's how the neighbors probably see it.
You might get more cooperation from the neighbors if you take the attitude that
they are entitled to the space. My strategy would be to open a discussion by apologizing to them for having to move the kid's bike, and wanting to know what they think might be the best set up for parking and storing the bikes and trailers.
This should lead to a dialog of each others needs and possibly lead to a better accommodation.
People are usually more cooperative when they are told they are right than when told they are wrong (even though they may have been wrong all along).
Good luck.
