Your point is very well taken. My grandson stayed with us this weekend, and he kept telling me that he wants to ride with me. My answer was that there is no place for him to sit. I did allow him to sit on the bike while it was on the stand, not running, and that seemed to satisfy him.
So far, I have not ventured out into traffic on the 'ped. Our neighborhood has lots of curvy streets and not much traffic, so I just stay in here. The speed limit on the main streets is 45, and the drivers are generally impatient and careless. So it's not likely that I would take him for a ride in South Florida traffic in a jury-rigged bike carrier. It was my hope that someone who reads this forum knew of a tested device that would be suitable for us to use.
I will not take any unnecessary risks with this little boy.
Thanks for the reply...
