> The bicycle, as we know it today, was not invented until the late 1800s.

Not sure why the article starts off with an incorrect hypothesis. There is evidence of bicycles in the sculptures in at least one Indian / Hindu temple Southern India. The temple dedicated to "Panchavarna Swamy" - 5 colored god, was built at least 1500 years old. (dated to the early 7th century by historians)
