Answer:
To inform readers about one reason why cycling was controversial in the 1800s
Step-by-step explanation:
The reason why the author mentions Dr. Richardson's research is to inform the readers about one reason why cycling was controversial in the 1800s.
Wheels of Change is a book written by Sue Macy about how important cycling was in the emancipation of women in late-nineteenth-century America. The purpose of the book is mostly to inform - not to persuade or entertain. Dr. Richardson is a prominent figure from that time, and Macy tells us about his opinion on this matter.
