>>1736412short slow rides on the flat, as a superior alternative to walking somewhere, or just to mess around, is not a niche use case. It's only niche if you had to have 1 bike only. Most people with multiple bikes would sometimes enjoy a comfy upright one if they took their heads out of their assholes.
dutch bikes are just not the best version of themselves because such things do not have to weigh 20kg.
