Well my lad, it's because we St. Paulites are just a little old-fashioned over on this side of the River. Why, we've just discovered the new-fangled "safety" bike over here. I'm confused and frightened by its noisy chain and mechanical contrivances, but it's a sure bet safer than navigating those blasted penny farthings down our fair boulevards. It's hard to dodge all the horses and buggies on those wretched contraptions. Just last week I was thrown from my trusty highwheel by a wayward mule!
