Don't worry, mom. We'll wear a helmet! This is a Columbia Light Roadster model bicycle from around 1888. It was made by Pope Manufacturing Company of Hartford, Connecticut. The dramatic difference in the size of the two wheels turned out to be a safety problem. It was easy to go flying over the handlebars—eek! The introduction of the safety bicycle with equal-sized wheels made the high-wheeler less popular, and Pope introduced a safety model in 1888.
