Does anybody who knows the history of cycling know if this is talking about "high wheel" (penny farthing) bikes or modern bikes with equal sized wheels? Changes the context rather if they mean high wheel bikes. The reference to bigger wheels and general suggestions of impracticality makes me think they might.
The illustration on this piece suggests 1874 is still high wheel bike territory: http://www.oldbike.eu/museum/wp-content/uploads/2011/07/1874...
