I also noticed this, and followed onto his page to find this fun! fact: > However, after marketing the velocipede, it became apparent that roads were so rutted by carriages that it was hard to balance on the machine for long, so velocipede riders took to the pavements and moved far too quickly, endangering pedestrians. Consequently, authorities in Germany, Great Britain, the United States, and even Calcutta banned its use, which ended its vogue for decades.
