Why I love biographical dictionaries (#2)

(Here's #1.)

A few sentences from the first paragraph of the entry on chemist Ida Freund (1863-1914), in the Oxford Dictionary of National Biography online; entry written by Marilyn Bailey Ogilvie:

"During her youth she lost a leg as a result of a cycling accident and the disease that followed. The artificial leg that replaced it was never very satisfactory. Throughout her life she moved about by means of a tricycle worked with the arms."

And I can't find any other mentions of Freund's tricycle anywhere. Anyone know more about it? There has to be an interesting journal article waiting to be written here--she was a chemistry demonstrator and then lecturer at Cambridge, 1887-1912, a gifted teacher, supporter of women students in the sciences, author of two textbooks. Her colleagues or students must have made some mention of her tricycle over the years?
