There are two NGOs that provide some bicycle training that I am aware. The league of American Bicyclist has a series of basic videos that will provide guidance. These are free. Cycle Savvy is the other. They have a set of 3 that cover beginner to advance. Right now, if they still have their deal going, it is $50 to join their organization and get the training.
They both offer live classes. I know people who have taken the LAB class and thought it was helpful. I do not know anyone that has taken the Cycle Savvy course.
I would suggest you start at the online LAB smart cycling videos to get a handle on your question.
