Ah, yes, how the bicycle eases our transportational needs, however odd they may be on occasion. This Copenhagener had issues with her foot. It's bandaged and wrapped in plastic.
Her companion walked alongside with crutches which were, I'm assuming, too cumbersome and slippery on the wintry sidewalks and crosswalks.
So... take a bike. Training wheels or not, it's still quicker and, most importantly, more comfortable. Viva la bicycle.
